Abstract :
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.
