摘要
通过定点定位观测及面上调查与分析 ,阐明了影响黑龙江省西部平原缓丘农区水土流失的主要因子是降雨量、土壤含水率、土壤容重及地表径流量 ,并给出了各因子之间的定量指标 ,为进一步加强和完善生态工程建设提供依据。
By means of location experiment and investigation it was described that main factors effecting soil and water losses in middle and lower reaches of the Nenjiang River are precipatation,soil moisture content,unit weight of soil and surface runoff,and quantitative index were given to provide the scientific basis for strengthening the ecological project construction.
