The forest in Dabie Mountain has great differences in elevation and obvious changes in vegetation. The height varies from more than 400 meters to 1700 meters, forming a rich and colorful forest landscape. The patches of plantations such as Cunninghamia lanceolata, Cryptomeria fortunei and Pinus massoniana at low altitude are rich and vast, with neat forest types and distinct layers. Cunninghamia lanceolata and Cryptomeria fortunei in the forest have tall and straight trunks and flourish; The branches of Pinus massoniana are vigorous and lush. Quercus variabilis, Cyclobalanopsis glauca, Liquidambar formosana and Dalbergia odorifera are full of vitality and thriving. Separated by a small piece of water, hidden in it. The altitude is getting higher and higher, and the landscape is different. On the steep rock between the cliffs, Huangshan solitary pine stands proudly and weathered. On the hillside, the Huangshan pine forest stands in the wind, the trunk is bent, and the branches are flag-shaped, which is beautiful and unusual. Different seasons have different scenery. In spring, flowers bloom, vegetation spreads, pine green and bamboo yellow, birds and flowers are fragrant; In midsummer, the trees are thick, the shade is heavy, the cool wind blows the muscles, and the summer heat is forgotten. From autumn to autumn, pine and bamboo are heavy, maple leaves are like fire, fruits are decorated with branches, and fragrant grass is fragrant. In winter, the wind swings in the forest, the snow presses the golden pine, and the mountains are dignified and dew-like; The snow on the top of the mountain is hard to disappear for a long time, and it blends with flowers and green leaves, so there is a beautiful view of "paradise snow".

Dabie Mountain, which spans Hubei, Henan and Anhui provinces, is the watershed between the Yangtze River and Huaihe River. Dabie Mountain in eastern Hubei is located at the southern foot of Dabie Mountain and in the east of Hubei Province. The geographical location is 29 45 ′ ~ 3L48 ′ n,114 ~16 07 ′ e, with high terrain in the northeast and low terrain in the southwest. The highest peak, Tiantangzhai, is 1729 meters above sea level, with a steep slope. The region belongs to the humid subtropical continental monsoon climate in East China, with abundant rainfall and heat, warm and humid climate, and the temporal and spatial distribution of water and heat is synchronous with the growth and development rhythm of natural vegetation and crops. The suitable climatic environment, complex and diverse geographical environment and unique geographical location make Dabie Mountain a meeting place of many flora plants, and the plant species and vegetation types are complex and diverse [1-2]. According to the data in recent years, the wild plant resources in Dabie Mountain in eastern Hubei Province were classified and statistically analyzed, and the ways of their sustainable utilization were discussed.

Tourism resources are the premise and foundation of tourism development. Tourism resources mainly include natural landscape tourism resources and human landscape tourism resources. Natural scenic tourism resources include mountains, canyons, forests, volcanoes, rivers, lakes, beaches, hot springs, wildlife and climate, which can be summarized into four categories: landform, hydrology, climate and biology. Cultural landscape tourism resources include historical and cultural sites, ancient buildings, ethnic customs, new achievements in modern construction, food, shopping, culture and art, sports and entertainment. , can be summarized into four categories: cultural scenery, cultural traditions, customs, sports and entertainment. Main characteristics: ① Regional differentiation characteristics: Tourism resources are the most basic factors that cause tourism activities. Without the regional differentiation of landscape, it is impossible to attract tourists with different needs. The regional differentiation of tourism resources is controlled by physical geography and the law of human social activities, while the former is more direct and obvious, such as the zonal distribution of latitude caused by climate differences; Longitude and latitude distribution characteristics affected by climate dryness and wetness; Vertical zonal distribution characteristics of air temperature and heat caused by height change; The concentration distribution characteristics formed by the comprehensive action of internal and external factors include particle size concentration, block concentration and strip concentration. (2) The characteristics of scenario combination include: similar combination and comprehensive combination in terms of species; From spatial group combination and off-site combination; In terms of scale, there are combinations of different sizes, including local or near-earth combinations and long-distance combinations. (3) The appearance features are similar, and the appearance of natural and human landscapes is similar, which not only brings convenience for tourists to travel near the ground, but also causes some problems for the development of tourism. For similar scenic spots, it is not easy to revisit many times and strengthen special publicity. In addition, there are characteristics of potential resources, seasonal changes and property changes. The value of statement 2 (1) has increased. (uniqueness) mainly used for viewing or appreciating. This is the main difference between tourism resources and general resources. (2) Spatial regionality. Regional differences are concentrated in the fact that tourism resources in different regions have different characteristics and tourist landscape charm. To a great extent, it determines whether the tourism industry of a country or region has achieved anything. (3) seasonality in time. (variability) mainly refers to the best viewing season of natural landscape affected by seasonal climate. (4) Sustainability in use. Mainly refers to the tourism resources are only for viewing, can not be taken away, and can be used by tourists for a long time. The premise is to protect and manage well. (5) the comprehensiveness or diversity of the landscape. Refers to the tourism resources are often composed of many factors. Statement 3 (1) All the factors that attract tourists with diversity are tourism resources. Demand varies widely, which can be summarized as "seeking beauty" and "seeking difference". In the vertical direction, people are full of admiration for distant ancient relics, while in the horizontal direction, people are obsessed with strange environments and things in different places. The instinctive pursuit of beauty makes people relaxed and happy in front of the beautiful natural landscape, and they are obsessed with the artificial creation that embodies human pursuit and condenses human wisdom. (2) Monopoly-(immovability) means that the physical body of tourism resources cannot move to tourists. It is the immovability of tourism resources that determines the temporality and remoteness of tourism activities; Consumers only buy images and feelings. (3) Positioning is the regional distribution of resources. Regional differences in geographical environment-people are eager to know the world outside their place of residence; Only then has formed the tourist flow which the tourist flows to a certain direction; The direction of tourism flow is the attraction of tourism resources. Second, the same tourism resources attract tourists geographically; Attractive to tourists from some countries or regions; Not attractive to tourists from some countries or regions; Not attractive to others. (4) Timeliness (supplementary content) The timeliness of tourism activities is mainly manifested in three aspects. The seasonality of time. It refers to the phenomenon that the same geographical environment changes with the seasons, and some special landscapes or special experiences are suitable for traveling in a specific season. Time specificity or periodicity: tourism landscapes and things appear or occur periodically within a certain period of time. Traditional festivals, the Olympic Games are held every four years after the Second World War; The biennial air show in Zhuhai, the annual carnival in Europe and America is coming; Every year in August of the lunar calendar, 16 Qiantang River watches the tide; Sunrise and sunset, the variability of the times: historical sites, celebrities' former residences, abandoned mines, prisons, etc. During the trip to the moon, some theme parks declined. (5) Combining an isolated landscape element or an independent scenic spot, it is difficult to form an attraction to attract tourists to leave their homes for special travel. What attracts tourists is always a complex, diverse, interrelated and interdependent combination of elements.
