摘要
以阴山北麓农牧交错区为研究区,基于InVEST模型土壤保持模块,定量评价了2000年、2015年区域土壤水力侵蚀量和土壤保持量,分析土地利用方式转变对土壤侵蚀和土壤保持的影响。结果表明:研究区水力侵蚀以微度侵蚀和中度侵蚀为主,2000年和2015年阴山北麓农牧交错区土壤潜在水力侵蚀量分别为9.37×10~7 t和1.46×10~8 t,实际土壤水力侵蚀量分别为6.31×10~7 t和1.01×10~8 t;从空间分布来看,多伦县、太仆寺旗、察哈尔右翼中旗、武川县潜在土壤水力侵蚀量和实际土壤水力侵蚀量较高;从时间序列来看,2015年潜在土壤水力侵蚀量、实际土壤水力侵蚀量和土壤水力侵蚀模数较2000年都有大幅度增加,2000年和2015年全区土壤保持总量分别为4.33×10~7 t和6.45×10~7 t,其中武川县、察哈尔右翼中旗和固阳县的土壤保持量较高。
Based on the InVEST Sediment Retention Model, the soil hydraulic erosion and soil conservation of the agro-pastoral ecotone in the north piedmont of Yinshan Mountain in 2000 and 2015 were evaluated. The impact of land use change on soil erosion and soil conservation was analyzed. Results showed that the amount of potential soil hydraulic erosion was 9.37×10^7 t and 1.46×10^8 t in 2000 and 2015, respectively. The amount of actual soil hydraulic erosion was 6.31×10^7 t and 1.01×10^8 t, respectively. As for the spatial distribution, the potential soil hydraulic erosion and actual soil hydraulic erosion were higher in Duolun County, Taupusi County, Chahar Right Banner and Wuchuan County. In terms of time series, the potential soil hydraulic erosion, actual soil hydraulic erosion and soil hydraulic erosion modulus increased significantly in 2015 compared to 2000. The total soil conservation were 4.33×10^7 t and 6.45×10^7 t in 2000 and 2015, respectively, and the soil conservation of Wuchuan County, Chahar Right Banner and Guyang County were higher than other counties.
