- Abstract:
-
Desertification control ecologincal function area of Hunshandake is fragile and an important part of ecological barrier in north China, which is located in the northern margin of the east Asian summer monsoon region. Wind erosion is one of the major ecological environmental problems faced by the Hunshandake region, and determines the degree of regional ecological security. In order to better clarify the situation of soil erosion in the region, we quantitatively analyzed spatial and temporal variation characteristics of soil erosion intensity in the past decade in desertification control ecologincal function area of Hunshandake region by RWEQ (Revised Wind Erosion Equation) model and analyzed the main influence factors of strong wind erosion area by the recoding superposition analysis technology of geographic information. The results show that the different of spatial distribution of wind erosion intensity in desertification control ecologincal function area of Hunshandake during the study period is obvious, indicating that the strong erosion area moves northwest and the soil erosion degree becomes more serious, all of these are jointly influenced by various factors such as vegetation coverage, climate condition, soil characteristics and terrain.
