摘　　要：应用弹性理论和灰色关联分析方法构建乡村生态环境与经济社会转型的响应模型,分析无锡市乡村生态环境对经济社会转型的响应过程及其耦合关系。结果表明,1978—2010年无锡乡村生态环境对经济社会转型表现为负向响应特征,响应强度曲线呈现出先增强后减弱的"倒抛物线"变化趋势;经济非农化是影响乡村生态环境的首要因素,1990年代中期以来的社会城市化以及2002年以来的经济外向化对乡村生态环境的影响不断加大;同时,乡村生态环境对经济社会转型也存在反馈约束作用,生态用地减少和环境质量下降是制约经济社会发展的显著因素。Rural ecological environment is evolving with the eco-social transformation in Wuxi, and some correlations could be found between the two. Based on the theory of elasticity and GRAP, modeling of response of rural ecological environment to eco-social transformation was completed for analysis of processes of the response and coupling relationship between the two. Results show that the rural ecological environment responded negatively to the eco-social transformation during 1978-2010, and strength of the response displayed a curve of inverted parabola＇ pattern, namely rising first and then falling. Non-agricuhuralization of the economy was the primary factor influencing the rural ecological environment. The influences of the social urbanization that started in the 1990s and the export-oriented economy that began in 2002 on the rural ecological environment have been growing steadily. And meanwhile, the changing rural ecological environment in turn affected the eco-social transformation. The decrease in ecological land and the deterioration of the environmental quality are the significant factors limiting the eco-social transformation.
