Turning over the world's vegetation map, along the Tropic of Cancer from east to west, the brownish-yellow color scale is not regretful to tell you: this is a daunting return to the desert zone. Crossing the vast desert or savanna, in the place located in latitude 23 ° 10 ′ north, longitude 112 ° 34 ′ east, you will be surprised to find a luxuriant oasis, like a brilliant emerald, set in the end of the return of the desert belt. This is the Dinghushan National Nature Reserve, known as the "green treasure trove on the desert belt".

Dinghu Mountain is located in Zhaoqing City, Guangdong Province, 86km from Guangzhou in the east, 3km from Xijiang River in the south, 18km from the center of Zhaoqing City in the west, and adjacent to Jiukeng in the north. Here, the peaks stand in line, full of verdure, ancient trees, birds and flowers; trickling streams, high waterfalls, the vast sea of forests, strange and colorful natural landscape, unique forest communities, colorful species resources are intertwined together, making it a place of natural treasures, and the "living nature museum" reputation at home and abroad.

Located in the northern edge of the tropics, the southern edge of the subtropics, warm and humid monsoon climate, it is the nature of Dinghushan

preferred, where the preservation and reproduction of many types of forest vegetation. Between the peaks, with the increase in altitude, from the foothills to the top of the mountain, natural vegetation such as gully rain forests, monsoon evergreen broad-leaved forests, evergreen broad-leaved forests, etc., are distributed in order. The former belongs to the tropical vegetation type, the latter belongs to the subtropical vegetation type, while the monsoon evergreen broad-leaved forest belongs to the transition type between the tropics and subtropics, which is unique to the southern subtropics of China. Coniferous forests, mixed coniferous and broad-leaved forests, and monsoon evergreen broad-leaved forests constitute a natural succession sequence and direction of forest vegetation. In addition, the riparian forests composed of water hyacinth, cattail and fishtail anemone are connected with the rainforests of the ravines and valleys, forming a curved jade belt that mirrors the streams, resembling a corridor and attracting attention. Among the many vegetation types, the monsoon broad-leaved evergreen forest and the ravine rainforest are the ones that best represent the forest area and landscape characteristics of Dinghushan.

The monsoon evergreen broad-leaved forest in Dinghushan Mountain has been preserved for nearly 400 years, which has its own special rules in species composition, community structure, growth and development, and evolutionary succession, reflecting the highest productivity level of the vegetation in this area and its natural resources, and it is a model for the study of natural ecological balance. Monsoon evergreen broad-leaved forests have a pale green appearance, a dense overlapping canopy, and a complex community hierarchy, which can generally be divided into five layers. Among them, trees can be divided into three layers, plus shrubs and young trees, herb layer. The first sublayer of the trees, composed of scattered masculine giant trees such as cone chestnuts and lotus trees, has a discontinuous, hemispherical forest canopy. These giant trees are more than 30 meters high, and it takes 3-4 people to join hands to enclose them. Tall trunks, rough bark and branches and tree tops that are getting old, on the one hand, indicate that they are the only one in the forest, irreplaceable elder status, on the other hand, it also indicates that they are about to finish their own life course after hundreds of years of vicissitudes of the wind and rain. The second sublayer of trees consists of major species such as the yellow-fruited thick-shelled laurel and thick-shelled laurel. Their trunks are straight, the bark is smooth; branches and leaves are luxuriant, lush, showing the vitality of the first, in time, they will replace the upper layer of tall old trees. From the third sub-layer of trees down, accompanied by colorful inter-layer plants, the species composition is complex and numerous, although not as dense and rich as tropical forest species, but reflects the original style of the South Asian tropical monsoon evergreen broad-leaved forest. It has important scientific research value.

Dinghu Mountain terrain, topography, the highest peak of the Jijiang Mountain elevation of 1000.3 m. Two from the northwest alone

Source of the stream, year-round splash, springs murmuring. After spanning the entire Dinghu Mountain, they merge into one at the southeast exit and eventually run to the Xijiang River. Warmth, shade, humidity and still winds make the area from Qingyun Temple to Hanshan Pavilion, as well as the valley of mountain streams near Baiyun Temple, distributed with gully rainforests unique to the subtropical south. The gully rainforest, which consists of Ficus convexus, Fritillaria, olive, and red bean with fat pods, is connected with the riparian forest at the bottom and the monsoon evergreen broad-leaved forest at the top. Although it is not as good as the real tropical rainforest in terms of the synthetic characteristics of the community, the external appearance, structure and species composition of the community have their own characteristics. When you look down from a height, these two streams are like the green ribbon worn by Miss Manners, and the rainforests growing in the gullies are just like the green stones inlaid on the ribbon, which dresses up Dinghushan Mountain in an enchanting way.

If in the ancient forest green sea, taste "to this has no dust half point, come up more than a thousand seek," the mood, it is refreshing. That strange, mysterious and mysterious tropical forest landscape, will make you will taste endless, stay and forget. In the shallow soil on the mountain slopes, the majestic plate-like roots, shaped like a board wall, and like the Kunpeng wings, extending in all directions, firmly supporting the face of Yan, Lychee and other sky-high trees, so that it is perched at the head of the forest canopy. That black, green, yellow, red, colorful, a thousand forms of vine plants, some round as thick as a python, some flat as a crawler, some are as slender as a silk thread, they are lying on the ground and line, while climbing the wall, around the tree; like a swing, like a rope pole, hanging in the air between the trees, intertwined horizontally and horizontally in the forest canopy, ubiquitous to show that they are devilishly high survival skills. Plant species on the fierce competition for living space, so that some epiphytes choose cone chestnut, lotus wood and other large trees old branches, as their own place of residence, brittle orchid, centipede vine, lion's tail, etc. in the branches and trunks of the land for the camp, will be their own developed root system deep in the bark between the fissures, and trickery, and flourish. They either climbed close to the trunk, or hanging upside down, graceful, elegant, like a garden in the air. The most cruel scene of survival competition in the plant world should be the phenomenon of strangulation, originally relying on animals and birds to carry seeds to the host branches and bark cracks, before they can sprout and grow banyan trees, not only do not know the favor, but insatiable, inch for inch, by virtue of their own hanging down the network of air roots, the host will be hugged and strangled to death, and then take over the host's position, to seek its own development. In the water tube wood, green fruit ficus and other mulberry banyan plants, as well as the trunk of the water Donggao, the strange phenomenon of flowering and fruiting, fishtail anemone is even more original from the stem or petiole from a large inflorescence, like Guanyin in the hands of the Magic Whip, upside down on the top of the stem, into a scene. In fact, most of the old stem flower plants for dioecious plants, will reveal their bright flowers in the most accessible position of insects, showing the plant on the pollination of insects a special adaptation. At this point, you have to marvel at the depth of nature.

Dinghu Mountain is full of treasures. Within 1133ha of the reserve, there are more than 2500 kinds of higher plants, accounting for about one fourth of the total number of plants in Guangdong. among 1845 kinds of wild higher plants, there are 22 kinds of state-protected plants such as spinulose tree ferns, zinnia wood, earth incense, etc., and there are as many as 30 kinds of endemic species and mode of origin species of South China, such as Dinghu holly and Dinghu camphor. The ancient relict plant Cyathea, known as living fossil, escaped the catastrophe of the Quaternary glacier and survived in Dinghu Mountain, although the wild number is very few, but the same brother, Cyathea nigra, chooses the shady, wet and wind-sheltered place to settle down, and has become a prosperous family. After 40 years of protection and reproduction, some rare and endangered species in Dinghu Mountain are no longer alone and not prosperous. Gewürztraminer has become a colony, sightseeing wood, the descendants of the chicken feather pine has long been integrated into the plant family, can be seen everywhere. And the long-leafed bamboo cypress has become a Dinghu Mountain unique species of street trees, welcome guests from all directions.

Species from all directions, compatible and coexisting, are gathered here, decorating Dinghu Mountain with flowers and full of vitality. In the spring, the round thick stem of the oil hemp vine, then opened a string of crystal clear, rich and moving flowers, the white white green, the red red purple, like a group of orderly arrangement, the wings want to fly in the Harvest Bird. On the sparsely wooded Azalea Hill, more than 20 kinds of South China azaleas are in bloom, red, white, fuchsia, pink, all over the hill, competing in spring. In early summer, cone chestnuts and lotus trees are in full bloom, with clusters of yellowish flower balls dotting the undulating and uneven forest canopy, glittering in the sunlight, thus attracting swarms of bees and butterflies. In the fall and winter seasons, the leaves of the mountain juniper, the sky material wood, and the mountain sebiferum turn from green to red, like a splash of blood color surging in the dark green bushes. The fruits of the fishtail anemone are as red as agate, like strings of Buddha beads, hanging upside down on the straight and upright stem, dazzling and eye-catching. Safflower oil tea that bright red fruit, will make you seem to walk into the apple orchard in spring and fall. And the rich, refreshing fragrance of osmanthus makes one's mind wander and drift.

Biologists call Dinghu Mountain a "treasure trove of species" and "gene repository", where there is a rich resource of plants and a variety of uses. There are excellent timber trees known for their hard wood, wild lychee

Species of more than 320 kinds of medicinal plants is more than 900 kinds of plants, in addition to the familiar Morinda citrifolia, cinnamon, He Shouwu, there are still chronic bronchitis can be cured of purple azalea, can be healed of liver disease of the yellow root bean, as well as Ganoderma lucidum, Mabo, Hawks Wormwood and other 58 kinds of medicinal fungi, more than 300 kinds of wild garden plants, the Guangdong Vanilla ornamental plants, the Guangdong Vanilla, the Guangdong Vanilla, the Guangdong Vanilla, the Guangdong Vanilla, the Guangdong Vanilla, the Guangdong Vanilla and other plants. More than 300 kinds of wild garden ornamental plants, such as Yue Wan Nian Qing, Everlasting Iron Horn Fern and various kinds of orchids, can beautify your living room while dressing up the nature and accompany you day and night. 20 kinds of wild fruits are closely related to people's life, and the wild lychee and wild longan of more than one hundred years old have been degraded and deteriorated, and are bitter and hard to swallow, but they are indispensable sources of genes for improvement, rejuvenation, and cultivation of new varieties. 10 kinds of health drink plants, such as bitter lilac, bitter linden and wild dragon eye are also important sources of genes for health care. Health care beverage plants, bitter tea, gibberellic acid has benefited the ordinary people, but by the contemporary literary hero Guo Moruo praised as "guests do not need tea and wine, purple-backed anemone poured cups" Dinghu specialty purple-backed anemone, due to the perseverance born in the cliffs and stone walls, the number of scarce and very precious. In addition, there are more than 180 kinds of oleaginous plants, more than 40 kinds of starch and aromatic plants, more than 110 kinds of fiber plants and more than 60 kinds of tanning plants. The countless resources of plants, for people to monitor, research, preservation, reproduction and utilization of natural resources provides a wealth of original materials.
