摘要生态系统健康是一门研究人类活动、自然生态系统、社会经济组织和人类健康的跨学科综合性学科。由于生态系统健康研究是一个新领域,有关它的概念、评价等方面还存在各种争论,在综合分析国内外生态系统健康和水土流失研究进展的基础上,联系对五华县的实地调查,提出水土流失地区生态系统健康的概念,运用"压力-状态-响应"模型对其生态系统健康进行分析评价,表明五华县的生态系统处于不健康的状态,进而提出水土流失地区新的修复方法,以优化水土流失地区的生态系统健康。 Ecosystem health is a multidisciplinary integrative field, which explores the interrelations between human activity, social organization, natural system, and human health. Ecosystem health assessment is still a new research field, and disputes existes on its concept and indices, which is what we should do to promote the research in the future. On the basis of synthesizing the research development of ecosystem health and soil erosion home and abroad as well as inspecting the soil erosion area in Wuhua County, the author puts forward the new concept of ecosystem health of soil erosion area. The new method of repairing unhealthy ecosystem of Wuhua County is put forward as a result by analyzing the ecosystem health in the soil erosion area through using ＂pressure-state-respond＂ model.
