滇西北云龙县2000—2020年土壤侵蚀时空演变特征及影响因素

Shuitu Baochi Xuebao
目的研究云龙县土壤侵蚀时空变化及影响因素对发展高山峡谷区的特色农业、生态环境治理修复和防治水土流失工作都具有重要意义。方法通过GIS手段和RUSLE模型，模拟研究云龙县2000—2020年土壤侵蚀状况的时空演变特征，分析特色农业与土壤侵蚀的关系，综合海拔、坡度、植被覆盖度、多年平均降水量和土地利用类型等影响因子，应用地理探测器模型进行土壤侵蚀影响因素的研究。结果1）2000—2020年云龙县每隔5 a 5期平均侵蚀模数分别为1 644、1 085、878、661、467 t/（km2·a ...

基于RUSLE模型和地理探测器的鄂西南土壤侵蚀脆弱性评价

Shuitu Baochi Xuebao
[目的] 水土流失是鄂西南突出的生态问题,合理评估该区域的土壤侵蚀脆弱性,并探究其驱动机制是采取有效水土保持措施的前提。[方法] 从人地耦合系统视角分析自然和社会经济因素对鄂西南土壤侵蚀的影响,从暴露度、敏感性和适应能力3个方面构建了鄂西南土壤侵蚀脆弱性评价指标体系,并采用综合赋权法确定指标权重。[结果] (1)2010—2020年鄂西南土壤侵蚀脆弱性总体上呈现先降低后升高的趋势,强烈及以上强度的土壤侵蚀脆弱性呈现零星的碎片化分布格局,且主要集中在鄂西南的中南部和东部宜昌市辖区的西部地区;(2 ...
