What are the 4 main factors affecting the formation and development of settlements

Topography, climate, transportation, resources

Climate, rivers, water sources in natural factors;

Politics, military, religion, transportation, agricultural production methods, cultural traditions, socio-economics, tourism, science and technology in human factors.

For example: 1. When the ancestors built their settlements, they had fully considered the conditions of topography, climate, and lighting. Among them, topographic conditions are the most important factors affecting the settlements. (1) On the river terraces which are close to water sources and will not be flooded. (2) In the higher regions of China, dominated by plateaus, the number of cities is less distributed and less populated; in the east, on the first terrace, the terrain is dominated by plains, so most of the cities and populations are distributed on them.

2, China's northern terrain is flat, belonging to the relatively open plains, the size of the village is generally larger, more regimented, checkerboard pattern; China's southern part of the complex topography of the hills, mountainous areas of the village's size is small, and the spatial distribution of the relatively decentralized.

3, from the unique topography of Lijiang Ancient City, China's northern terrain is flat, belonging to the relatively open plains, the village is generally larger in size, more regimented, checkerboard pattern; the south of China's hilly and complex terrain, mountain villages are small in size, and the spatial distribution of relatively decentralized. The microclimate conditions formed to analyze the formation and development of the settlement. Its north of the Elephant Mountain, Jinhong Mountain, west of the Lion Mountain, is the ancient city against the northwest wind in autumn and winter natural barrier, resulting in its winter without severe cold; the ancient city is located in the Yunnan-Guizhou Plateau, the terrain is high, 2400 meters above sea level, according to the law of vertical differentiation of temperature, so that the summer without the heat. Therefore, Lijiang Old Town has a pleasant climate in all seasons, which provides very favorable natural conditions for the formation and development of the Old Town. And from the Lijiang dam flat and east and west of the open terrain conditions and the Jade River water of the Yulong Snow Mountain provides a stable and sufficient water conditions, but also very conducive to the formation and development of settlements.
