摘要：
Agriculture is a conflict region for economical development and environmental protection, and agroecosystem health assessment is its foundation of sustainable development. Based on the character of agroecosystem and PSR (Pressure-State-Response) model, this paper selected some indicators of agroecosystem health and constructed the model of matter-element evaluation, which is applied to seven towns in DXQ (Daxing District) and got the following results: WSZZ (Weishanzhuang Town), LXZ (Lixian Town) are 'healthy'; CZYZ (Changziying Town), ADZ (Anding Town) and YHZ (Yinghai Town) are 'critical state'; XHMZ (Xihongmen Town), JGZ (Jiugong Town) are 'unhealthy'. The results are basically consistent with facts of seven towns, so the index system and method of evaluation are feasible.
