摘要
以云龙水库流域为研究对象,采用室内解译和野外验证相结合的方法,利用"3S"技术进行土壤侵蚀遥感影像解译,收集土壤侵蚀相关指标并同时进行野外验证,以了解云龙水库流域土壤侵蚀程度。结果表明:(1)利用"3S"技术进行土壤侵蚀现状调查,速度快,精度高,验证正确率达96.2%;(2)全流域土壤侵蚀面积248.53km2,占土地面积的33.36%;其中轻度侵蚀面积113.27km2,中度侵蚀面积115.63km2,强烈侵蚀面积18.97km2,极强烈侵蚀面积0.66km2;(3)流域内土壤侵蚀量共113.34!104t,平均土壤侵蚀深1.13mm。调查结果可为云龙水库流域土壤侵蚀动态监测和管理提供参考。
This article take Yunlong Reservoir Basin as the object of study,the combination of indoor interpretation and field verification,remote sensing image interpretation of soil erosion using“3S”technology,soil erosion related indexes were collected and field verification was carried out at the same time.After the interpretation,verification,calculation and analysis of relevant indicators,the results show that:(1)Using technology to investigate the status of soil erosion,high speed,high precision,verify the correct rate of96.2%;(2)In the basin soil erosion intensity classification with micro degree erosion,mild erosion,moderate erosion,strong erosion,very strong erosion;the whole basin soil erosion area248.53km2,33.36%of land area accounted for;the mild erosion area113.27km2and moderate erosion area115.63km2,intensity erosion area18.97km2and strength erosion area0.66km2;(3)The amount of soil erosion in the watershed was113.34Million tons,and the average soil erosion depth was1.13mm.
