The main reason for the good soil and water conservation in the Changbai Mountain area of China is t

Xinjiang has a large area, but the area of soil erosion is small, the main natural reasons are the arid climate, less precipitation, fewer rivers, small flow, weak erosion of flowing water, and the vegetation condition of the mountains is also relatively good.

In the Changbai Mountain area, the precipitation is concentrated and the light is sufficient, which is conducive to the growth of plants, and the typical vegetation includes coniferous forest, coniferous and broad-leaved mixed forest, deciduous broad-leaved forest and meadow grassland, etc., due to the high vegetation coverage, so the soil erosion is less.

Soil erosion in the mountainous areas of Xinjiang is relatively light, mainly because Xinjiang is located in an inland area, with relatively little precipitation, relatively few rivers on the surface, relatively weak erosion by flowing water, and relatively good vegetation conditions in the mountainous areas.

The soil erosion in the Changbai Mountains is relatively light, mainly because the climate here is relatively humid, the forest coverage rate is relatively high, and because of the high latitude here, the river freezes for a long time, and the erosion force on the ground is relatively weak.

Soil erosion in China is serious, with an annual topsoil loss of more than 5 billion tons, ranking first in the world. The area of desertified land in China has increased by more than 1,000 square kilometers per year on average, and even in the south of China, which has always been deprived of deserts, patches of desert land have appeared. China's forest resources in some important forest areas have a decreasing trend, such as the Changbai Mountain forest area in Northeast China, the forest coverage rate has decreased by about 18 compared with the early days of the founding of the People's Republic of China

Vertical change --- elevation.

The ups and downs of the terrain will obviously affect the climatic conditions of various places, from the flat land to the top of the high mountains, the climatic conditions vary greatly, with the increase of altitude, temperature, precipitation, atmospheric humidity, wind, light and other climatic factors and their coordination will vary greatly. Therefore, in the higher altitudes of the mountain, from the foot of the mountain to the top of the mountain, you can see that the plant species are constantly changing, and the vegetation type and rent splitting are also changing accordingly, forming a certain vegetation vertical.

The disparity in precipitation on both sides --- land and sea.

Changbai Mountain is northeast-southwest trending, southeast and offshore, and is affected by the warm and humid airflow from the ocean, forming a rich topographic type of fine rain.

Hence the precipitation.

The northwest side of the mountain is a rain shadow effect area, which is land, less affected by ocean currents, and has less precipitation.

The main influencing factor of the vertical change of vegetation in Changbai Mountain is altitude! The higher the altitude, the lower the temperature.

The main influencing factors of the disparity in precipitation on both sides of the Changbai Kuanjue Mountain are sea and land factors. The seaward side is affected by the wet air currents from the ocean, and there is a lot of precipitation. And because the mountains have a blocking effect, there is less precipitation on the other side!

Reasons for the location of land and sea.

Changbai Mountain is northeast-southwest trending, and the southeast of the mountain is the Sea of Japan and the Yellow Sea, respectively, and there are warm and humid air currents from the ocean, so the climate is humid and coarse.

To the northwest of the mountain is the northeastern region of China, which is inland, and there are cold and dry aircurrents from Siberia, resulting in less precipitation.

Precipitation directly affects the differences in vegetation.

The influence of topography on climate, under normal circumstances, every 100 meters of height, the temperature drops about the height of Changbai Mountain, and the temperature is low in Changbai Mountain, which is the main reason for the vertical change of vegetation At the same time, the blocking effect of the mountain range on the low-level air movement makes the moisture and temperature conditions of the windward slope and the leeward slope of Changbai Mountain also different
