Environmental governance plays a pivotal role in promoting the high-quality development of environment, and the implementation of source control and zoning management is the foundation of the refined governance of environmental space. This paper aims to put forward the theoretical and technical methods of regional environmental function management and control zoning, and carry out an empirical study on Shengzhou city, Zhejiang province. First, a spatial structure model of the environmental pollution sources (EPSs) for human activities, which is composed of control units (CUs) and hierarchical control areas (HCAs), has been formed and identified. Then, the solid waste, air pollutants and water pollutants are selected as the main pollutants, and the single evaluation and weighted sum have been measured for each CU. Finally, according to the spatial classification of the CUs and the integrated eigenvalues, key countermeasures and supporting projects of each HCA are proposed. The main results are as follows: (1) Shengzhou city has a total of 18 CUs, which can be divided into 6 HCAs. HACs of levels Ⅴ and Ⅳ are the areas where pollutants are discharged intensively, with integrated eigenvalues of 11 and 10 respectively. The CUs, including refuse landfill, sewage-treatment plant, high-pollution industrial zone, livestock and poultry farm, mining area, and basic industrial zone, have hugh impact on water and atmosphere, and have great hazards. It is necessary to promote the resource utilization of industrial and mining production space in the key area of environmental governance. (2) The emissions of pollutants in the HACs of levels Ⅲ and Ⅱ are medium or even less. The CUs of level-Ⅲ HAC cover urban settlements, rural settlements and transportation land, with integrated eigenvalues of 6 and 7. It is important to improve the collection and treatment technology of solid waste and sewage in all living space. In addition, HAC of level-Ⅱ includes two CUs, which are cultivated land and garden plot, with integrated eigenvalues of 4. It has a small amount of agricultural solid waste and sewage discharge, therefore, it is urgent to solve the problems of non-point source pollution and eutrophication. (3) HACs of level-Ⅰ is composed of forest land, garden land, water area, bare land and other ecological space, with more emphasis on ecological protection function. Large scale industrialization and urbanization are prohibited in the area. HAC of level 〇 highly overlaps ecological redline, which requires complete prohibition of human activities and the elimination of external environmental impact.
