黄土丘陵区农业生态安全评价指标体系的建立

Establishment of Evaluation Index System of Agriculture and Ecology Security in the Loess Hilly Region

以构建黄土丘陵区农业生态安全评价指标体系为研究目的,通过区域性与科学性结合,完整性和相对独立性结合,可行性和可操作性结合,可比性和针对性结合的指标选取原则,采用“压力一状态一响应”(PSR)概念模型结合黄土丘陵区面临的生态环境问题,提出符合该区实际的农业生态安全评价指标体系。该指标体系分为系统压力、系统状态、系统响应三大部分,由10个一级指标,21个二级指标构成。

This article aims to construct an evaluation index system of agriculture and ecology security in the loess hilly region using the index selecting principle which combines regional features with scientific-foundation, integrality with relative independence, feasibility with operation, and comparison with pertinence. In order to present the evaluation index system which conforms to this area, the conceptual model of the ＂Pressure-Condition-Response＂ （PSR） is used with the ecological problems in the loess hilly region considered. The index system includes the three parts of system pressure, system condition and system response, which is composed of 10 first-grade indexes and 21 second-grade indexes.
