- Abstract:
-
In order to explore the dual effects of land use/cover change on soil erosion and its driving forces in Yanhe River Basin, provide a basis for soil and water conservation and ecological environment construction in the future, based on GIS and RS technology, the response model of soil erosion to LUCC was constructed. The results showed that during 1980—2018, soil erosion and soil conservation effects caused by LUCC, coexisted in the Yanhe River Basin, with soil erosion effects weakening and soil conservation effects intensifying; furthermore, under the same period, soil erosion and soil conservation caused by LUCC offset each other; from 1980 to 1990, LUCC caused soil erosion effect, while from 1990 to 2018, LUCC caused soil conservation effect; from 1980 to 1990, LUCC-caused soil erosion effect was mainly driven by population growth and the intensive development of agriculture to meet human needs; from 1991 to 2010, LUCC-caused soil conservation effect was mainly driven by policy, urban construction, industrial restructuring, and other socioeconomic development; and from 2011 to 2018, it was mainly driven by the urbanization of the population, and land policies was also at play. It was concluded that before 1990, driven by population increase, LUCC caused soil erosion effect, and after 1990, mainly affected by economic and policy factors, LUCC mainly caused soil conservation effect in Yanhe River Basin.
