摘要
从水资源承载力的定义出发,在现有研究成果的基础上建立了区域水资源承载力评价多目标优化模型,并给出了简化条件下的简便解法。采用文中所给出的水资源承载力评价模型,按现状生活水平和小康型生活水平两种情况进行了廊坊市区域现状水资源承载力计算。计算结果表明,就现状生活水平和经济结构而言,廊坊市社会经济发展规模明显超出了水资源的承载能力,提高用水功效,特别是提高农业用水功效,以及调整经济结构是提高水资源承载力的有效途径。
In the paper, starting from the definition of water resources carrying capacity, a multi-objective optimization model is established for sestaming regional water resourse carrying capticity based on current results of regional water resource carrying capticity and the handy solution of the multi-object optimization model is given with predigested conditions. Applying the multi-object optimization model given in this paper, the current regional water resources carrying capacity in Langfang are estimated with current standard of living and xiaokang standard of living. The results of estimation show that the scale of society economy in Langfang exceeded local water resources carrying capacity and advancing water-utilizing effictency, especially in agriculture, and adjusting economic construction are effective ways of advancing regional water resources carrying capacity.
