摘　　要： 在对郊区环境组成、结构、生态环境特征等区域研究的基础上 ,以边缘效应的理论为出发点 ,深入分析了城乡交错带的几个生态环境建设问题。认为郊区生态建设应以 (1)城市废弃物的再生地 ,(2 )生态旅游与农业文化的消费地 ,(3)现代持续农业的先导区等为目标。最后分析了城乡交错面 (边缘界面 )对城乡复合生态系统中环境应力的聚合放大效应 。 Based on the regional study of composition and structure of suburban environment and characteristics of suburban eco environment, with the theory of edge effect as its starting point,profound analysis was made of problems in construction of eco environment in regions interlacing city and countryside. It was held that construction of suburban ecology should be oriented towards: (1)a site for regeneration of urban wastes;(2)a place for consumption,like ecological tourism and agricultural culture;and (3)a pioneer region of modern sustainable agriculture. The aggregating and enlarging effect of the city countryside interlacing regions(marginal interface)on environmental stress in the urban and rural compound ecosystem was analyzed. It has been pointed out that the regulating of suburban agro ecological environment is an essential measure of preventing the conflict between city and the countryside from aggravating.
