摘要
探索基于区域资源禀赋、地域功能适宜性及现实政策条件的生态产品分区是生态产品价值实现的空间发展指引.文中以宿迁市为例,基于地域系统理论"要素-功能"分析范式,引入国土空间用途管制规则和政策条件双重约束,建立了耦合"开发潜力-布局适宜性"的生态产品分区理论框架,采用双变量局部空间自相关与耦合协调模型划分了生态产品开发、拓展、保育分区类型,明确差异化生态产品开发策略.结果显示:宿迁市生态产品高潜力区面积 603.31km2、中等潜力区面积 1752.19km2、低潜力区面积 6168.48km2,分别占国土总面积的7.07%、20.56%和72.37%;生态产品适宜区面积2432.15km2、中等适宜区面积2666.87km2、不适宜区面积2432.15km2,分别占国土总面积的28.56%、31.32%和40.12%.以乡镇为单元,划分生态产品优先开发利用区52 个、适度拓展区28 个、保育培育区38 个,耦合"潜力-适宜性"的生态产品分区对生态资源权益交易、梯度化生态产业体系塑造等制度设计提供了方法支撑.
Abstract
Exploring ecological product zoning based on regional resource endowment,regional functional suitability,and practical policy conditions is a spatial development guide for realizing the value of ecological products.This study takes Suqian City as an example,based on the analysis paradigm of"element-function"in regional system theory,introduces dual constraints of land use spatial control rules and policy guidance,and establishes a theoretical framework for ecological product zoning that couples"development potential-layout suitability".The bivariate local spatial autocorrelation and coupling coordination model are used to divide the types of ecological product development,expansion,and conservation zoning,and clarify differentiated ecological product development strategies.The results show that the high potential area,medium potential area,and low potential area of ecological products in Suqian City are 603.31km2,1752.19km2,and 6168.48km2,respectively,accounting for 7.07%,20.56%,and 72.37%of the total land area.The suitable area for ecological products is 2432.15km2,the moderately suitable area is 2666.87km2,and the unsuitable area is 2432.15km2,accounting for 28.56%,31.32%,and 40.12%of the total land area,respectively.Taking townships as units,52 ecological product priority development and utilization zones,28 moderate expansion zones,and 38 conservation and cultivation zones are divided.The ecological product zoning coupled with"potentiality-suitability"provides methodological support for institutional design such as ecological resource rights trading and gradient ecological industry system shaping.
