摘  要：
在第二松花江流域选取黑土层厚度、土壤侵蚀、土壤理化性状、坡耕地治理共4类因子作为坡耕地生态环境诊断的初选指标,构建了包含10个评价指标的坡耕地生态环境诊断体系,并运用多目标线性加权函数法对坡耕地生态环境进行了健康诊断与评价。评价结果表明,第二松花江流域坡耕地生态环境系统综合健康诊断指数为18.10,健康水平较差,等级为劣,应当加强水土保持和生态建设力度。

摘  要：
It selected 4 kinds of factors of thickness,soil erosion,physicochemical properties of black earth and slope farmland management in the second Songhua River basin as primary indexes for diagnosing the ecological environment of slope farmland,and established a diagnosing system of the ecological environment of slope farmland including 10 evaluation indexes.It diagnosed and evaluated the ecological environment of slope farmland by using the method of multi-objective linear weighting function.The outcomes show that the integrated diagnosed health index of the ecological environment of slope farmland of the basin is 18.10.It shows that the health level is lower,the grade is poor and the effort for soil and water conservation and ecological building should be strengthened.
