城市适宜水域面积计算模型与方法研究

Study on calculation model and method of suitable water area of city

在分析我国城市水域面积与水资源条件、土地资源之间关系的基础上,探讨了确定城市适宜水域面积的方法,该方法通过建立城市水域的生态效益函数和建设成本函数,以边际效益和边际成本相等为确定适宜水域面积的均衡条件。经郑州市郑东新区城市水域面积实证分析,取得了实用性成果与结论。

Based on the analysis of the correlation among the city water area,water resources condition and land resources,the calculation method of city suitable water area is discussed herein.Through establishing the eco-benefit function and construction cost function of city water area,this method takes the equivalence between the boundary benefit and the marginal cost to determine the equilibrium condition for the city suitable water area.Through an empirical analysis made on the water area in Zhengdong New Distri...
