黄河泥沙淤改造地区域综合效应评估研究

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。
