水资源综合利用专项规划评估体系构建及应用

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

水资源综合利用专项规划作为城市规划的组成部分,在指导绿色生态城区水系统建设方面发挥着越来越重要的作用.为科学评估水资源综合利用专项规划实施效果,构建规划评估体系,建立包含编制内容、实施效果及保障机制的多维度的全过程评估指标体系.基于多个水资源专项规划和中国南京市河西新城绿色生态城区阶段性运营评估项目,确定水资源综合利用专项规划评估指标权重.以南京河西新城水资源综合利用专项规划为例作实证研究,分析水资源专项规划文本的完整性及合理性;通过实地勘查考察河西新城建设进度,检测地表水水质等,明确专项规划实施效果,建立保障机制.采用偏差分析方法对评估结果进行梳理,找出南京河西新城水资源综合利用专项存在的问题,并为专项规划修编提出建议.规划评估结果显示,水资源综合利用专项规划基本达到指导城市水资源综合利用系统建设的目标,水资源综合利用系统建设在规划引领下,取得了一定成效;构建的指标体系可多角度评估水资源综合利用专项规划实施效果,可为其他地区的水资源专项规划编制提供借鉴.

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.
