南阳市水资源承载能力计算分析

Analysis of Water Resources Carrying Capacity Calculation in Nanyang

对南阳市水资源条件及开发利用状况进行分析研究,采用用水总量指标、地下水开采量、地表水利用率等单项指标和综合计算评价等方面计算了南阳市及各县区水资源承载能力,评价了水资源承载现状,分析了超载成因,提出有关对策和建议,为下一步更好地开发利用和保护水资源提供了借鉴。

The water resources condition and exploitation situation of Nanyang are analyzed in this paper.The carrying capacity of water resources in Nanyang and its counties is calculated by using single indicators such as total water consumption index,groundwater exploitation amount and surface water utilization rate and comprehensive calculation and evaluation.In addition,the current situation of water resources carrying capacity is evaluated.The causes of overloading are analyzed as well.Some relevant countermeasures and suggestions are put forward,which provide reference for better exploitation and protection of water resources in the next step.
