摘要
环境管控单元是"三线一单"中落实生态环境准入清单的基本载体,其划定结果直接影响清单的编制和管控要求的落实.本研究分析了现有环境管控单元划定方法,总结了行政边界拟合法和要素分区聚类法 2 种主要划定方法的优缺点,发现拟合法划定结果应用优势明显,但易出现优先保护单元划定偏小、优先保护区所在单元主导功能不一致的问题.本研究结合市、镇 2 级单元实际案例,提出结合地形地貌和交通网络优化环境管控单元边界的方法,为"三线一单"更新调整提供环境管控单元优化思路.
Abstract
The environmental integrated units have been treated as the basic carrier to implement lists of Environmental Permits for Human Activities(LEP),which is a part of the"Three Lines One Permit"(TLOP)policy.The defining results of environmental integrated units directly affect the establishment and implementation of LEP.This study analyzed the current division methods of environmental integrated units,then summarized the advantages and disadvantages between administrative boundary fitting method and partition clustering method.The result showed that the administrative boundary fitting method had obvious advantages for application,but there still existed problems that the area of the priority protection unit was rather small and its dominant function was inconsistent.Therefore,based on the cases of city units and town units,a optimization method to set boundaries of environmental integrated units by combining topographic features and traffic network was proposed,which provided an optimization approach for the update and adjustment of TLOP.
