摘　　要：生态环境管控单元是实施生态环境分区管控的重要基础,科学合理划定及更新生态环境管控单元是完善“三线一单”生态环境分区管控制度的关键技术难点。在梳理全国各省(区、市)“三线一单”生态环境管控单元划定方法的基础上,以H省全省及其A市、B市、C市3个城市为例,对比分析了要素叠加并集(叠加法)和拟合行政边界阈值(拟合法)2种生态环境管控单元划定方法的结果差异性;讨论了不同自然地理条件、生态环境功能特征下2种划定方法的适用性,建议优先采用叠加法划定生态环境管控单元,并提出了不同地形区域拟合法划定阈值标准的范围与建议。以期为优化“三线一单”生态环境管控单元划定技术方法、完善生态环境分区管控制度、提升生态环境精细化管理水平和治理能力提供技术支撑。The integrated ecological environment units are important basis for the implementation of the ecological environment zoning control.The scientific and reasonable delineation and updating of the integrated ecological environment units are the key technical difficulties in improving the ecological environment zoning control system of"Three Lines One Permit".On the basis of sorting out the overall application of the zoning methods for integrated ecological environmental units in all the provinces(autonomous regions and mulicipalities)of China,taking H Province and its three cities A,B,and C as examples,the differences in the results of two zoning methods of element merging method(merging method)and administrative boundary threshold fitting method(fitting method)of integrated ecological environment units were compared and analyzed,the applicability of two zoning methods were discussed under different geographical conditions and ecological environment function characteristics.It was suggested that the merging method should be preferred to delineate the integrated ecological environment units,and the scope and suggestions for the threshold standards in different terrain areas by fitting method were proposed,to provide technical support for optimizing the technical methods of delineating the integrated ecological environment units in"Three Lines One Permit",improving the zoning management and control system of ecological environment,and improving the fine management level and governance ability of ecological environment.
