一般性生产生活用水对水域生态系统价值的损益分析

水域生态系统是人类社会赖以生存和发展的生态系统之一,一般性生产生活用水在带来经济效益的同时,对水域生态系统造成了很大的生态价值损失。本文分析了一般性生产生活用水对水域生态系统中水文循环以及水域生态环境的影响,并研究了其对水域生态系统价值的损益情况,探讨了水循环价值损失、污染净化价值损失、防止地面沉降的价值损失等三方面的价值损失计算公式,以及工业供水效益、农业供水效益以及生活用水供水效益等三方面的计算公式。最后本文以杨凌示范区为案例,分析了一般性生产生活用水对杨凌示范区水域生态系统的影响,并计算了一般性生活生活用水对杨凌地区水域生态系统的损益价值。

The analysis of the profit or loss on the value of water ecosystems of industrial and potable water

Water ecosystem is one of the ecological systems of the survival and benefits of Human being;Generally industrial and potable water brought economy benefits,in the mean time,it also caused a great loss of ecological value.This paper analyzed the impact of the general industrial and potable water on the hydrological cycle and water ecological environment,studied the profit and loss of the value of water ecosystems,and discussed the loss calculation formula for the water cycle value loss,the loss of value of pollution purified,to prevent land subsidence value losses;and formula for industrial water supply efficiency,the efficiency of agricultural water supply,and domestic water supply effective.Finally,taking Yangling Demonstration Zone as an example,it analyzed the water ecosystems and calculated its value of the profit or loss in the area.
