| 摘 要： | 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。 |
| 关 键 词： | 黄土丘陵区 农业生态安全评价 指标体系 |

| Abstract: | This art icle aims to const ruct an evaluat ion index system of agriculture and ecology security in the loess hilly region using the index selecting principle which combines reg ional features with scientific foundation, integrality with relat ive independence, feasibility w ith operat ion, and comparison w ith pert inence. In order to present the evaluation index system w hich conforms to this area, the conceptual model of the/Pressure) Condition ) Response (PSR) is used with the ecological problems in the loess hilly reg ion 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. |
| Keywords: | loess hilly region security evaluation of agriculture and ecology index system |
