江苏沿海地区水资源承载力研究——以盐城市为例

Water resource carrying capacity in coastal areas of Jiangsu Province: Example of Yancheng City

区域水资源承载力是进行生态环境建设和确定社会经济发展的基础。根据水资源承载能力评价指标体系建立的原则,将盐城市发展分为水资源、社会经济以及生态环境3个子系统,构建了水资源承载力模糊综合评价模型,并应用该模型对盐城市水资源进行综合评价。结果表明:盐城市水资源开发利用已达到相当规模,在现有经济技术条件下,该地区的水资源承载潜力已相对较小,水资源供需矛盾突出。提出提高水资源承载力的对策,为该区域今后水资源开发利用提供依据。

The regional water resource carrying capacity is of great importance to the eco-environmental construction and socio-economic development. In the light of the principles for establishment of evaluation system of water resource carrying capacity,3 subsystems of water resources,socio-economy and ecoenvironment are listed for the development of Yancheng City. A fuzzy comprehensive evaluation model for water resource carrying capacity is established, and it is applied in Yancheng City. The results indicate that the development and utilization of water resources in Yancheng City has reached a considerable scale under the existing economic and technological conditions.The potential of water resources is relatively small,and the contradiction between water supply and demand is obvious. Some measures are proposed to improve the water resource carrying capacity.
