In order to further build a good natural ecological environment, we can explore the application of "three lines and one list" ecological environment zoning management and control technology, and improve the overall level of ecological environment protection and control. The article mainly focuses on the "three lines and one list" ecological environment zoning management and control technology and methods for in-depth exploration.展开更多
