【摘要】：文章引入SD方法,以水资源有偿使用制度为例,构建了水资源制度的生态经济效应仿真模型.模型分为五大子系统:人口子系统、经济子系统、水资源自然子系统、水生态环境子系统、水资源制度子系统,包括60多个变量和30多个系统方程.以浙江省2009年为启动年份,模拟了2009到2013的结果,进行了模型验证,然后设置了现状方案及水资源有偿使用三种方案,进行了水资源有偿使用制度仿真模拟研究;结果发现生活用水量、工业用水量、污水排放量、工业万元GDP用水量、工业单方水产出等生态经济效应指标都随着方案的不同有所变化,农村和农业征收水资源费将会推进农村生活用水减少和农业节水,第三产业和工业增加水资源费将会提高水资源经济效应,同时在相同产值情况下会减少污水排放量.
[Abstract]:This paper introduces SD method, taking the system of paid use of water resources as an example, constructs a simulation model of ecological and economic effects of water resources system. The model is divided into five subsystems: population subsystem, economic subsystem, water resources natural subsystem, water ecological environment subsystem, water resources system subsystem, including more than 60 variables and more than 30 system equations. The results from 2009 to 2013 were simulated in Zhejiang Province in 2009, and the model was verified. Then, the current situation scheme and three schemes of water resources paid use were set up, and the simulation research on the system of paid use of water resources was carried out. The results showed that the indexes of ecological and economic effects, such as domestic water consumption, industrial water consumption, sewage discharge, industrial ten thousand yuan GDP water consumption, industrial unilateral aquatic production and so on, all changed with different schemes. The collection of water resources in rural areas and agriculture will promote the reduction of domestic water consumption and agricultural water saving in rural areas, and the increase of water resources fees in tertiary industry and industry will increase the economic effect of water resources and reduce the discharge of sewage under the same output value.
