- 摘要:
- 为了探究延河流域土地利用/覆被变化对土壤侵蚀的双重效应及其驱动力,为今后水土保持和生态环境建设提供依据,采用构建土壤侵蚀对LUCC响应模型的方法,结合GIS和RS技术进行了研究。结果表明:(1)1980—2018年期间,延河流域LUCC引起的土壤侵蚀效应和土壤保持效应共存,土壤侵蚀效应在波动中减弱,土壤保持效应在波动中增强;(2)同一时期内,LUCC引起土壤侵蚀效应和土壤保持效应相抵后,1980—1990年,LUCC引起土壤侵蚀效应,1990—2018年,LUCC引起土壤保持效应;(3)1980—1990年,LUCC引起土壤侵蚀效应主要受人口增长驱动,为满足人类需求,大量开垦耕地,增加建设用地,1991—2010年,LUCC引起的土壤保持效应主要受政策驱动,城市建设、产业结构调整等社会经济发展也起到一定作用,2011—2018年,LUCC引起的土壤保持效应主要受人口城市化的驱动,土地政策也起到一定的作用。可见,1990年之前,受人口增加驱动,延河流域LUCC引起土壤侵蚀效应,1990年之后,主要受经济、政策等因素的影响,延河流域LUCC主要引起土壤保持效应。
- 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.
