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.

Key words: construction land expansion of village and town, ecological environmental effect, coupling and coordination, Rongchang District of Chongqing Municipality
