基于RUSLE模型的京津冀地区土壤侵蚀时空变化分析
Temporal and spatial variation analysis of soil erosion in Beijing-Tianjin-Hebei region based on RUSLE model
摘要
Abstract
[Objective]Soil erosion is an increasingly serious ecological problem,which has become a global environmental chal-lenge and poses a great threat to human survival and sustainable development.[Methods]Therefore,based on multi-source remote sensing data,the dynamic changes of soil erosion in Beijing-Tianjin-Hebei region from 1990 to 2020 are studied by RU-SLE model and geographical detector model,and its driving factors are analyzed.[Results]The result show that:(1)From 1990 to 2020,the distribution of soil erosion in the Beijing-Tianjin-Hebei region shows an overall pattern of southeast low and northwest high,with slight and mild erosion being the main types,accounting for 73.79％of the total.(2)In most areas of Beijing-Tianjin-Hebei,the soil erosion level is mainly shifting from high to slight and mild intensity,with a transition ratio of over 50％,showing an overall improvement but with some areas worsening.(3)The explanatory power of each influencing factor to soil erosion is:slope＞elevation＞land cover type＞vegetation coverage＞rainfall＞population density＞GDP.[Conclusion]The relevant conclusion can provide some scientific reference for soil erosion control and prevention,and can also provide refer-ence for soil erosion control in other areas.关键词
