Path of Rural Sustainable Development Based on the Evolution and Interaction of Rural Functions:A Case Study of Chongqing Municipality,China

In order to investigate the evolutionary characteristics of rural functions and their interaction,37 districts and counties in Chongqing,China are used as research objects to measure the level of rural functions and analyze the interaction between rural functions using entropy value method and spatial autocorrelation method.The results show that from 2009 to 2019,the three main functions of production,living and ecology in Chongqing’s villages have been greatly enhanced,especially the production function.On the whole,the production and living functions are stronger in the western part,while the ecological functions are significant in the eastern and southern parts of Chongqing,with some differences in local spatial characteristics.This finding is consistent with the regional economic and social development of Chongqing.In addition,the interaction between rural functions is also evident.In general,production and living functions are mainly expressed in synergistic relationships.Ecological and production functions,including ecological and subsistence functions,mainly present a trade-off relationship.The interactions between rural functions also show clear spatial and temporal differences.In addition,different regions have different comparative advantage functions,and in this study,the counties of Chongqing are classified into four types.Policy makers are advised to adopt different measures according to the different types to promote sustainable rural development by coordinating the’production-living-ecological’functions of rural areas.This study reveals the spatio-temporal evolution of rural functions and the interaction between rural functions,which can provide theoretical support and practical reference for rural revitalisation and sustainable development.

基于乡村多元价值的乡村振兴类型与路径——以重庆市为例

【目的】本文旨在解构乡村多元价值的内涵,测度重庆市乡村多元价值水平,为进一步促进重庆市乡村振兴提供理论支持与实践指导。【方法】基于2020年重庆市乡村矢量数据与属性数据,运用变异系数法确定权重,构建乡村多元价值评价模型,测度重庆市37个区县的乡村多元价值水平并分析其空间格局,在此基础上运用区位熵法识别乡村多元价值短板。【结果】2020年重庆市乡村多元价值总体上呈现出“南高北低,高值集聚分布、低值点缀”的空间格局。具体地,重庆市乡村经济价值呈现出“西高东低,高值显著集中”的空间特征;乡村社会价值“西高东低”;乡村生态价值“由渝东北、渝东南向西逐渐递减”;乡村文化价值呈现出“高值点缀,低值连片分布”的空间格局。按照“分区—划片—重点”的思路,结合区位熵法计算结果,将重庆市乡村分为了9种类型。【结论】以乡村空间为介质探讨了乡村多元价值的实质与表征,为不同乡村类型提出了乡村振兴路径。研究结果可为激发乡村内生发展动力,推进乡村振兴提供理论支撑与实践指导。

村镇建设用地扩展与生态环境效应的耦合协同规律及类型甄别--以重庆市荣昌区为例

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。
