摘　　要：农业是经济发展与环境保护矛盾最突出的区域,农业生态系统健康评价作为农业可持续发展的基础研究,应得到足够的重视。本文根据农业生态系统的特征和压力-状态-响应P(SR)模型,选取了若干较为公认的反映农业生态健康的指标,依据其意义建立了类型识别的物元评判模型。应用于大兴区7个乡镇,得到了以下结论:农业生态系统处在“健康”标准的有魏善庄镇、礼贤镇;处在“临界状态”标准的有长子营镇、安定镇、瀛海镇;处在“不健康”标准的有西红门镇、旧宫镇。评价结果基本与实际相符,说明建立的评价方法是切实可行的。Agriculture is a conflict region for economical development and environmental protection. We should attach importance to agroecosystem health assessment because of its foundation of agricultural sustainable development. Based on the character of agricultural ecosystem and Pressure-State-Response model, this article selected some indicators of agricultural ecosystem health and constructed the model of matter-element evaluation, which is applied to 7 towns in Daxing District and got following results. The final evaluation results for evaluation in Weishanzhuang Town, Lixian Town were “healthy”. Those for Changziying Town, Anding Town and Yinghai Town were “ordinary”, and those for Xihongmen Town, Jiugong Town were “not healthy”. The results are basically consistent with facts of seven towns,so the index system and method of evaluation are feasible.
