摘要
以我国南方岭南丘陵地区风化壳离子型稀土矿区为研究对象,利用多时相卫星遥感影像数据对研究区土壤侵蚀状况进行了动态分析,得到不同强度土壤侵蚀面积变化的总体趋势,并依据土地覆盖类型对导致不同强度侵蚀区面积变化的因素进行了分析,揭示了稀土矿开采对土壤侵蚀的影响。
It conducts dynamic analysis of soil erosion status of the studied area by taking weathered crust-eluvial rare-earth mining area of South China as an object of study and using multi-temporal satellite remote sensing image data.It obtains an overall trend of soil erosion area variation with different intensities,analyzes the factors that caused soil erosion area variation with different intensities according to the types of coverage and reveals the influence of rare-earth mining to soil erosion.
