| 摘 要： | 在东北黑土区,水土流失是生态安全最重要的胁迫因子.从水土流失的角度出发,通过对东北黑土区水土流失成因、危害、现状以及防治等4方面因素的具体分析,引入一系列相关评价指标,结合指标选取的一些基本原则,参考压力(P)-状态(S)-响应(R)模型框架模式和专家的建议,对初选指标进一步筛选和分类,建立了东北黑土区水土流失胁迫下的生态安全评价指标体系.该指标体系分为系统压力P,系统状态S,系统响应R共3大部分;由8个一级指标,21个二级指标构成.

| Abstract: | Soil and water loss is the most important stress factor to ecology security in black soil region of Northeast China. Based on the concrete analysis of the causes,hazards, and present status of soil loss and its prevention in black soil region of Northeast China,some indexes related to soil loss were introduced. Accord-ing to the index selection principles and by referring to the model of Press (P)-Status(S)-Response (R)and the suggestions from several experts,the primary selection of indexes were made further and classified.Finally an evaluation index system of ecology security under soil and water loss stress in black soil region of northeast China was established, which is composed of 8 first-grade indexes and 21 second-grade indexes |
