以沂蒙山区为典型区域 ,分析了鲁中南山区生态系统的脆弱性及其形成原因。指出农业生态环境退化是人类长期不合理垦殖活动作用于脆弱生态系统的结果。社会经济落后与生态系统脆弱有密切关系。发展生态农业是维护山区生态平衡 ,保持农业持续发展的必由之路。
Yimeng mountain area is situated on the fringe of weak ecological area in north China. The main factors that cause ecosystem weak are interfacial climate(which Changing vate of precipitation is big, 20 %～25 %)and mountain to pographic features(which relative height is high and cutted mash). The situation of hydrothermal has obvious transition in this area. The main reasons of agricultural ecology environment degradation are crisis ecosystem and the iufluence of human. Taking nine poverty counties of Yimeng mountain area as targets, this paper points out that there are raltions between the poverty of social and economy and fragile of ecosystem. By the principle of ecology programming, Yimeng mountain area was classified into five agricultural ecotype. By the analysis of the ecological benefit and the social economical benefit of ecological agricultural economy construction of Yimeng mountain area, we think that it is the only way of richness that develop ecological agricultural economy for poverty area.
