摘要

根据农业生态系统的内涵,从农业生态系统的活力、组织结构、恢复力3个方面选取25个评价指标,依据层次分析法系统化的思维原理,建立了农业生态系统健康的评价指标体系。用所建立的农业生态系统健康评价体系,以张掖市为例开展实证分析。结果表明:张掖市农业生态系统健康情况堪忧,只有高台县和肃南县的农业生态系统处于亚健康状态,其他区县均处于病态状态。张掖市农业生态系统主要问题存在于农业生产结构不合理,耕地数量与质量不稳定、森林覆盖率偏低等。针对其问题,提出调整产业结构,合理生产布局;稳定耕地面积,提高耕地质量;发展绿色农业生产,推广有机肥使用;保护自然资源,提高绿植覆盖率等对策建议。
        Referring to the connotation of agricultural ecosystem, 25 evaluation indexes were selected from 3 aspects of vitality, organizational structure, and resiliency of agricultural ecosystem to establish the health evaluation index system of agricultural ecosystem according to the principle of systematic analytic hierarchy process. The agricultural ecosystem of Zhangye City was taken as an example to carry out the empirical analysis by the established health evaluation system. The results showed that the health of agricultural ecosystem of Zhangye City was worrying. Except Gaotai County and Sunan County were in subhealthy state, agricultural ecosystems of other counties were in morbid state. The main problems of agricultural ecosystem in Zhangye included unreasonable structure of agricultural production, unstable quantity and quality of cultivated land, and low forest coverage rate. Based on the problems referred, advices are proposed such as adjusting industrial structure and optimizing production layout, controlling cultivated area and improving the quality of cultivated soil, developing green agriculture production and promoting the utilise of organic fertilizer, protecting natural resourse and increasing vegatation coverage.
