水土保持对径流泥沙及养分流失的影响研究

摘要

水土流失过程中,必然产生大量的土壤泥沙流失,导致区域间土壤稀少及土壤中的养分降低.水土流失不仅会导致区域生态系统严重失衡,而且会影响当地农业生产实践活动.文章以辽宁省某区为例,对研究区内的水土流失这一典型生态问题展开分析,着重探讨水土保持对当地径流泥沙及养分流失产生的影响.%Soil sediment loss will be produced during the course of soil and water losses,causing the soil scarce between the regions and soil nutrient reduced.Taking a region of Liaoning Province as the example,soil erosion within the researched area,the paper conducted the analysis on the typical ecological problem,and discussed in emphases soil and water conservation's impact on local runoff sediment and nutrient losses.
