通过网格划分，可深入分析网格水环境状况、污染成因与问题，明确各网格管理

By meshing, the mesh can be in-depth analysis of water environment, pollution and causes of the problem, clear each grid management direction to form a detailed list of specific environmental problems at the river basin level. On this basis, the establishment of local management and hierarchical classification management, and "transverse to the edge, vertical in the end" management model basin, long arms like a big net, the various environmental issues do not stay dead land "Clean Sweep "raise the overall level of meticulous management environment.

Through grid division, we can analyze the state of grid water environment, pollution causes and problems in depth, clarify the direction of grid management, and form a detailed and clear list of environmental problems at the basin level. On this basis, the establishment of territorial management and hierarchical classification management, "horizontal to the edge, vertical to the end" of the watershed management model, like a large network of omissions, will all kinds of environmental problems do not leave a dead end "one network to play", improve the overall level of environmental refinement management.

Through grid division, the water environment, pollution causes and problems of the grid can be analyzed in depth, the management direction of each grid can be defined, and a detailed and clear list of environmental problems can be formed at the basin level. On this basis, the watershed management mode of "horizontal to side, vertical to the end" should be established by combining territorial management and classified management at different levels, which is like a large network without omission. It will "eliminate all kinds of environmental problems in one network" and comprehensively improve the level of environmental fine management.<br>
