Spatial Characteristics and Zoning Regulation of Typical Rural Areas Based on the Function of"Produc-tion-life-ecology"
Accurately understanding the spatial characteristics of rural land and optimizing regulation is a key aspect of fully utilizing land functions and ensuring land safety.It serves as an important foundation for regional functional positioning,resource protection,and rational development.Based on the"production-life-ecology"functional perspective,this study integrated a functional evaluation system and a coupling coordination model to examine the spatial characteristics of rural land in Donghai County,Jiangsu Province,and to measure the coupling coordination of the"three life"functions.Using functional comparative advantage and system clustering meth-ods,five types of advantageous functional zones in Donghai County were identified,with tailored regulatory measures proposed for each area's characteristics.The results indicated that the functional index thresholds for the"production-life-ecology"subsystems were[0.04-0.43],[0.05-0.26],[0.01-0.18],and[0.06-0.32],respectively,showing a high degree of consistency between subsystems and the overall function,while notable heterogeneity was present due to regional characteristics and external factors.Overall,the cou-pling coordination of the"three life"functions was good,with 47.06%of areas classified as moderately coordinated and 11.76%as disordered,exhibiting an"east high,west low"spatial pattern.Based on the RCA index and coupling coordination,the five-category optimization zoning of rural land space aligned closely with the actual conditions of the study area.On the basis of clarifying the de-velopment positioning of each zone,Donghai County should emphasize the integration of principal and coordinating functions,fully leverage the comparative advantages of each region,thereby creating a cumulative effect and promoting high-quality overall regional development.In conclusion,this paper offeres differentiated development suggestions based on local resource endowments,providing important theoretical support and practical reference for optimizing the rural land space in Donghai County.
