| 摘 要： | 研究水资源对产业的贡献度和生态环境效益可以为合理配置水资源提供依据.首先,通过分析山西省水资源的状况,在改进的C-D模型的基础上,测算出水资源对区域生产总值的贡献度为-1.3％,其中第一、二、三产业分别为2.11％、0.50％和-1.56％,在此基础上定量分析山西省生产用水对经济的作用;其次,以森林生态系统为例,核算山西省2003和2010年森林生态服务功能价值分别为974.08亿和1000.21亿元,相应的用水量分别为3.1亿和3.4亿m3,并分析山西省森林生态用水的效益.针对山西省生产用水与生态用水配置存在的浪费、污染严重的问题,提出节约用水、防治水污染、保障生态用水等对策.

| Abstract: | The analysis of the degree of water contribution to industry and benefits of ecological water can provide reference for the rational allocation of water resources. Firstly the water utilization in Shanxi Province was analyzed in this paper, its contribution to GDP was calculated based on improved C-D model. The contribution was about - 1.3% , in which the primary, secondary and tertiary industries, contributed 2. 11% , 0.50% and - 1.56% separately. Secondly, the benefits of ecological water in Shanxi were analyzed from the perspective of forest ecosystems. It was calculated that the service function value of forest ecosystems in 2003 and 2010 was 97. 408 billion and 100. 021 billion yuan, and the corresponding water consumption is 310 million and 340 million m3. Aimed at the pollution and waste problems in production and ecological water allocation in Shanxi Province, countermeasures such as water saving, water pollution control and prevention, ecological water protection etc. are put forward. |
