【摘要】：本文基于流域水环境管理技术(水专项)在辽河流域的实施,以逻辑框架法(LFA)评估模型为基础,在清河流域尺度对流域水生态环境改善的效果进行评估。进行基于PSR模型的目标分析,寻求“因果关系”,即通过对管理技术分类集成,梳理管理技术的体系中的水质标准明确、企业排放值明确、优化产业结构和智能化管理政策这些“因”形成了对流域水生态系统健康和水生态承载力这两方面个“果”的改善,构建了“目标树”。构建了垂直逻辑关系,明确了投入、产出、效果、目标；构建了水平逻辑关系,通过对投入活动、产出成果、直接效果和实现目标的验证,证明了垂直逻辑关系的成立。对于直接效果的水平验证中,采用主成分分析法和关联性分析对清河流域优化出的14个采样点和断面的指标进行优化与权重判断,提出了适用于清河流域的水生态系统健康指标体系,对2011～2013年水生态系统健康评价,得出2013年好于2012年好于2011年；提出清河流域水生态系统承载力指标体系,应用TOPSIS法对2011～2013年清河流域水生态系统承载力进行排序,得出2012年好于2013年好于2011年,验证了水环境管理技术实施后对以上两方面均有改善提高作用。通过对水平逻辑关系的层层验证,直至最后得到了逻辑框架矩阵中目标的实现,即对水生态环境有提高作用效果。
[Abstract]:This paper is based on the implementation of water environment management technology (water project) in Liaohe River Basin and the LFA-based evaluation model. The purpose analysis based on PSR model was carried out to find "causality", that is to say, the classification and integration of management technology was carried out to evaluate the effect of water ecological environment improvement on the scale of Qinghe River basin. Combing the management technology in the system of water quality is clear, enterprise emission value is clear. The optimization of industrial structure and intelligent management policy have resulted in the improvement of water ecosystem health and water ecological carrying capacity, and the target tree has been constructed, and the vertical logical relationship has been constructed. The input, the output, the effect, the target; Build the horizontal logic relationship, through the input activities, output results, direct effect and the realization of the goal of verification, proved the establishment of vertical logic relationship. For the direct effect of horizontal verification. By using principal component analysis and correlation analysis, the indexes of 14 sampling points and sections were optimized and the weights were judged, and the index system of water ecosystem health was put forward. According to the assessment of water ecosystem health from 2011 to 2013, 2013 is better than 2012. The index system of carrying capacity of water ecosystem in Qinghe River Basin was put forward, and the carrying capacity of water ecosystem in Qinghe River Basin was sorted by TOPSIS method. It is concluded that 2012 is better than 2013 better than 2011, which verifies that water environment management technology can improve and improve the above two aspects after the implementation of water environment management technology. Finally, the realization of the goal in the logical framework matrix is obtained, that is, the effect of improving the aquatic ecological environment.
