摘要:
为防治生态脆弱区土壤侵蚀,以十大孔兑上游为研究区域,通过GIS软件运用RUSLE模型和基于土地类型方法,分别选取1980年、1990年、2000年、2010年及2018年5个典型年份,研究了十大孔兑上游流域土壤侵蚀空间分布动态变化特征并对比了两种方法有效性。结果表明:十大孔兑上游流域土壤侵蚀以无明显侵蚀和中度侵蚀为主,基于两种方法计算轻度及以上等级侵蚀面积都分别呈现1980—1990年增加、1990—2018年减少趋势,说明该区域土壤侵蚀得到了有效治理。通过两种方法对比发现RUSLE方程考虑因子更为全面,模拟更接近实际,同时适用于水土流失定量研究。
Abstract:
In order to prevent and treat soil erosion in the ecologically fragile area, taking the upstream of the ten tributaries as the research area, we used the RUSLE model and land-based methods through GIS software, selected 5 typical years of 1980, 1990, 2000, 2010 and 2018, respectively, and studied the dynamic characteristics of the spatial distribution of soil erosion in the upstream of the ten tributaries and compared the effectiveness of the two methods. The results show that the soil erosion in the upstream of the top ten tributaries is mainly non-obvious erosion and moderate erosion, and the calculated erosion area of mild or above grade based on the two methods shows a trend of increase in 1980—1990 and decrease in 1990—2018, respectively, indicating that the soil erosion situation in this region is gradually improved. It is found that the factor of RUSLE equation is more comprehensive, the simulation is closer to the reality, and is also applicable to the quantitative study of water and soil loss by comparing the two methods.
