安阳市现状水资源承载力研究

在阐述水资源承载力概念和模型研究的基础上,探讨了现状水资源承载力的概念,明确提出了水资源承载力的“协调发展”模型,估算并评价了安阳市现状水资源承载力。研究认为,目前的供水量在平水年只能满足安阳市现阶段(2002年)人口的温饱型生活需要,不能满足现阶段人口在总体小康型、全面小康型和初步富裕型阶段的需要,且各阶段超载人口逐渐增多;在枯水年,现状水资源承载力的数量、类型和平水年相比必然有趋于一致或加剧趋势。

Actual water resources carrying capacity in Anyang City

On the basis of the concept and model of water resources carrying capacity(WRCC),the concept of actual WRCC was discussed.A harmonious development model for WRCC was put forward and applied to the calculation and evaluation of actual WRCC in Anyang City.It is concluded that,under the condition of normal flow years,the present water supply only meets the need of the subsistence level for the present population(2002) in Anyang,but can't suffice the levels of development in the general well-off phase,overall well-off phase and primary surplus phase.Furthermore,overweighted population is increasing in every phase. Compared with the normal flow years,the quantities and types of WRCC have an equal or intensifying trend in low flow years.
