Establishment and application of special plan evaluation system for comprehensive utilization of water resources

Abstract

As an integral part of urban planning, the special plan for comprehensive utilization of water resources plays an increasingly important role in guiding the construction of water system in green ecological urban areas. In order to scientifically evaluate the implementation effect of the special plan for comprehensive utilization of water resources, this paper constructs a plan evaluation system, and establishes a multi-dimensional and whole process evaluation index system including the preparation content, implementation effect and guarantee mechanism. Based on a number of water resources special plan and the stage operation evaluation project of Nanjing Hexi New District Green Ecological City, the weights of of evaluation indices of water resources comprehensive utilization special planning are determined. Finally, taking the special plan for comprehensive utilization of water resources in Nanjing Hexi New District as an example, this paper analyzes the integrity and rationality of the system, and inspects the construction progress of Hexi New District through field investigation, and detects the surface water quality within the plan scope, so as to clarify the implementation effect of the special plan and establish the guarantee mechanism. At the same time, the deviation analysis method is used in the planning evaluation to find the planning problems of the comprehensive utilization of water resources in Nanjing Hexi New District, and put forward suggestions for the revision of the special plan. According to the results of planning evaluation, the special planning of comprehensive utilization of water resources has basically achieved the goal of guiding the construction of urban water resources comprehensive utilization system. Under the guidance of the special plan, the construction of water resources comprehensive utilization system has achieved certain results. The index system constructed in this paper can evaluate the implementation effect of water resources comprehensive utilization special plan from multiple perspectives, and has a certain reference significance for the compilation of water resources special plan in other regions.
