• 摘要：立足新时期国土空间规划体系强化全域环境空间管控，推动各类环境要素管控分区降尺度与融合化，实现环境污染源头管控与精准落地，是系统应对当前高强度、复合型环境问题的有效途径.构建基于国土空间规划的全覆盖、多层级环境功能分区管控体系，在单要素人为污染物排放量和综合排放强度评价基础上，提出环境功能分区的管控等级集成评价模型，探索分区管理和分级施策的全域环境空间管控途径，并以高度工业化和城市化的苏州市为案例开展应用研究.结果表明：①基于国土空间规划体系的"三区三线"与现行环境要素管控分区的空间耦合性，建立由8个一级分区和21个二级分区构成的环境功能分区管控体系；②按照"三区三线"管控属性和综合排放强度，可进一步将环境功能分区的管控等级由高至低划分为Ⅴ、Ⅳ、Ⅲ、Ⅱ、Ⅰ及○级；③苏州市人为污染物排放量总体偏大，城镇空间内的工矿业生产空间及城乡居住空间、农业空间内的生产养殖空间的综合排放强度较高，主要分布于姑苏、虎丘等中心城区及昆山、常熟等工业集聚区；④苏州市Ⅴ级和Ⅳ级管控区以工矿业生产空间、城乡居住空间和特殊生产空间为主，Ⅲ级管控区以混合空间为主，Ⅱ级以农业种植空间和生产养殖空间为主，Ⅰ级和○级管控区主要包括一般生态空间和生态保护红线.案例应用表明，国土空间规划体系下的全域环境空间管控可操作性强，可实现环境规制精准落实到污染源空间；建议以环境功能分区分级管控体系为基础，将环境空间管控全面融入国土空间规划体系，建立综合施策的环境协同管理机制.

• Abstract：Based on the territorial spatial planning in new era, it is an effective way to deal with the current high-intensity and complex environmental problems to strengthen the global environmental space control, promote the downscaling and integration of various environmental factors, and realize the precise control of environmental pollution sources. This paper constructs a full-coverage and multi-level environmental function zoning management and control system based on territorial spatial planning, puts forward an integrated evaluation model of control level of environmental function zoning on the basis of the evaluation of emission amount and comprehensive emission intensity of single-factor anthropogenic pollutant, explores the regional environmental spatial management and control approach of zoning management and hierarchical implementation, and takes Suzhou City, a highly industrialized and urbanized city, as an example to carry out application research. The results show that:① based on the spatial coupling between the territorial spatial planning system and the current environmental factors control zonings, the environmental function zoning control system is established, which consists of 8 primary partition units and 21 secondary partition units.② According to the control attributes of the "three zones and three lines" and comprehensive emission intensity, the control level of environmental function zoning can be further divided into Ⅴ, Ⅳ, Ⅲ, Ⅱ, Ⅰ and 0 from high to low. ③ The overall anthropogenic pollutant emission in Suzhou City is large. The comprehensive emission intensity of industrial and mining production space (IMPS) and urban and rural living space (URLS) in urban space, and production and breeding space (PBS) in agricultural space is relatively high, which is mainly distributed in the central urban areas such as Gusu and Huqiu, and industrial agglomeration areas such as Kunshan and Ghangshu. ④ IMPS, URLS and special production space (SPS) are the main control units of level-Ⅴ and Ⅳ hierarchical areas. The zoning units of level-Ⅲ hierarchical area are mixed. The agricultural planting space (APS) and PBS are the main control units of level-Ⅱ hierarchical area. The general ecological space (GES) and the ecological redline (ERL) are the main control units of level-Ⅰ and 0 hierarchical areas. The case application shows that the regional environmental spatial control under the territorial spatial planning system has strong operability and can realize the accurate implementation of environmental regulation to the pollution source space. It is suggested that based on the environmental function zoning management and control system, the environmental space management should be fully integrated into the territorial spatial planning, and the environmental collaborative management mechanism of comprehensive policy should be established.
