| 摘 要： | 村镇建设用地扩展不可避免地挤压生态系统空间,打破系统内部原有的生态环境和生物地球化学过程,在生态文明的时代背景下,如何处理好村镇建设用地扩展与生态环境保护的关系对于实现可持续发展至关重要。论文在厘清村镇建设用地扩展与生态环境效应耦合协调机制的基础上,通过构建评价指标体系分析了2008—2018年重庆市荣昌区村镇建设用地扩展与生态环境效应协调发展的时空演变格局并划分耦合协调发展类型。研究发现：① 村镇建设用地扩展与生态环境效应以人类活动为纽带而构成交互耦合体,解析二者的耦合协调关系为理解村镇建设中“发展”与“保护”这对矛盾体提供了通道。② 2008、2013、2018年荣昌区村镇建设用地扩展与生态环境效应的耦合协调度在时间上呈上升趋势,在空间上呈南北高、中间低的分异格局。③ 运用耦合协调模型并结合同步发展模型将荣昌区村镇划分为保护与发展同步型、生态环境支持型、生态环境损耗型3种耦合协调类型。④ 针对各耦合协调类型提出差异化调控策略：保护与发展同步型村镇应兼顾经济发展与生态保护;生态环境支持型村镇可以适量开发未利用地;生态环境损耗型村镇应改变生态环境效应滞后的现状。 |

| Abstract: | The expansion of village and town construction land inevitably squeezes the ecosystem space and disrupts the original ecological environment and biogeochemical processes in the system. Under the background of ecological civilization, how to deal with the relationship between village and town construction land expansion and ecological environment protection is a very important question for realizing sustainable development. On the basis of clarifying the coupling and coordination mechanism between village and town construction land expansion and ecological environmental response and taking 2008, 2013 and 2018 as the study years and Rongchang District of Chongqing Municipality as the study area, this study constructed the evaluation indicator systems of village and town construction land expansion and ecological environmental effect. Using the coupling and coordination index calculation model and synchronous development model, this study analyzed the change of temporal and spatial patterns of village and town construction land expansion and ecological environment response in Rongchang District, and divided the types of coupling and coordinated development. The results show that: 1) The expansion of village and town construction land and the response of ecological environment form an interactive coupling relationship with human activities as the link. The analysis of the coupling and coordination state of the two provides a channel for understanding the conflict between development and protection in village and town construction. 2) The coupling and coordination degree of village and town construction land expansion and ecological environmental response in the district showed an upward trend temporally and a low differentiation pattern in space between the north and south. 3) Using the coupling and coordination model and combined with the synchronous development model, the village and town in Rongchang District were divided into three coupling and coordination types: protection and development synchronization type, ecological environment support type, and ecological environment loss type. 4) Differentiated regulatory strategies should be implemented for various types: village and town with protection and development synchronization should give consideration to both economic development and ecological protection; village and town with ecological environment support can develop an appropriate amount of unused land; and village and town with ecological environment depletion should change the current situation of lagging ecological environment protection. |
