基于现状调研的鹿亭乡水土保持成效分析

Analysis on the Effect of Soil and Water Conservation in Luting Township Based on the Current Situation Investigation

浙江省水土流失的类型主要是水力侵蚀,余姚市鹿亭乡作为皎口水库的上游,水质的优劣直接影响着宁波城区供水的质量。文章以2020年第七次水土流失遥感普查资料为基础,以现状调查为手段,主要目的是调查研究鹿亭乡全域的水土保持生态环境现状以及水土流失的动态变化情况。结果表明:鹿亭乡水土流失主要集中在水土流失强度为轻度的侵蚀区,其中25°以下的坡度区域水土流失面积占比较大,水土流失动态趋势发展较慢,水土保持现状较好。

The type of soil and water loss in Zhejiang Province is mainly hydraulic erosion.Luting Township of Yuyao City,as the upstream of Jiaokou Reservoir,the quality of water directly affects the quality of water supply in Ningbo City.Based on the seventh remote sensing census of soil and water loss in 2020,the main purpose of this paper is to investigate and study the current situation of soil and water conservation ecological environment and the dynamic changes of soil erosion in the whole area of Luting Township.The results show that the soil and water loss in Luting Township is mainly concentrated in the erosion area where the intensity of soil erosion is mild.The area of soil and water loss in the slope area below 25°accounts for a larger proportion.The dynamic trend of soil and water loss develops slowly and the current situation of soil and water conservation is good.
