基于生态经济理论的生态需水计算方法研究

在简述生态需水研究现状的基础上,结合以可持续发展为基础的生态经济理论,提出了基于生态经济思想的生态需水概念,并进行了理论分析.根据生态经济领域中的生态价值理论,确定不同生态需水量条件下的生态价值,进而通过水资源的生态价值与经济价值之间的相互关系确定合适的生态需水量,并通过实例对该方法的具体步骤进行了说明,认为由该法所确定的生态需水量符合客观实际,可以作为生态建设过程中生态需水研究的方法之一.该法通过水资源将生态系统和经济系统联系在一起,对于研究可持续发展条件下的水资源利用有一定的现实意义.

Calculation method for ecological water demand based on theory of ecological economy

In this paper, we firstly, introduce the present research situations about ecological water deman, develop and analyze theoretically, a new method for calculating the ecological water demand,combining the ecological economy theory based on sustainable development. According to the ecological value theory, the ecological values for different ecological water demand are confirmed. The relationship between ecological value and the economic value of water resources is used to confirm the ecological water demand. A case is used to show the concrete steps of this method. The ecological water demand confirmed by this method fit with actual conditions, and can be used to study the ecological water demand theory during environment construction. In this method, the ecological system and the economy system are combined together by water resources. And this method has significance for studying the water resources utilization in the condition of sustainable development.
