摘要
本文对沿黄涝洼地泥沙淤改造地这一项目的综合效应进行评估,评估内容包括:经济效应、社会效应、生态效应及其组成的综合效应。根据指标选择的科学性、实用性、相对独立性、可操作性和可比性等原则,分别建立经济、社会、生态环境指标体系。其中经济指标包括单位土地面积纯收入、人均GDP、农村人均纯收入;社会指标包括土地利用率、灌溉面积率、人均耕地面积、供水能力;生态环境指标包括森林覆盖率、沙化土地比、土壤侵蚀比、地下水位变化、区域景观美观度。在建立一系列综合效应评价指标体系后,在典型区内运用模糊数学法对淤改造地的综合效应进行客观评价,估算淤改造地所带来的经济、社会、生态、综合效益,通过分析数据得到总体评价,以此指导沿黄涝洼地综合整治的实施。
In this paper,a synthetical effect assessment was carried on the silt＇s being transformed into fertile farmland,which includes three contents：economic effect,social effect,ecological effect and the combined effect of the three.According to the scientific nature and the feasibility principle,independent character,manipulate and relativity,evaluation index system will be established,including the economic,the ecological,and the social indicators system.In this system economic indicators include net income per unit land area,average GDP per person,and net income per country dweller;social indicators include land-use capability,irrigated area rate,average cultivated area per person,water furnishing ability;while ecological ones include round-off work,desertification land ratio,soil erosion ratio,the change of the subsoil water level,region landscape artistic.Through the establishment of a series of synthetical effect evaluating indicator system,fuzzy mathematics method will be applied in a typical region to evaluate the effects of the changement into land,and it will bring about the economic and social benefit which is brought by the transformation as well as eco-efficiency.After the assessment the obtained data will be analyzed to direct the implement of the saline silt along the Yellow River.
