| 摘 要： | 以天津市宝坻区里自沽大型灌区的基本资料为基础.选取灌溉水利用系数、渠系水利用系数、田间水利用系数、灌溉水生产效率、耕地有效灌溉率、节水灌溉工程面积率6个指标,构建了模糊综合评价模型,对影响灌区用水综合效益的因素进行了分析.结果表明,2004-2008年,里自沽大型灌区综合评价指数分别为3.299、3.423、3.624、3.679、3.687整体上呈现明显的上升趋势,其用水效率状况处于较好阶段.利用模糊综合评价法,对灌区用水效率与效益进行了评价.结果表明,工程状况与管理水平对于灌区用水系数的影响较显著.必须加大灌区节水改造以及灌区管理体制改革力度,进一步提高农业灌溉水的利用效率和效益,促进水资源的可持续发展.
