| 【目的】定量研究水资源的价值量和价格，为水价制定和水资源管理提供参考。【方法】根据景观水资源利用的特点和作用，将水资源价值分为自然资源价值、旅游景观价值及居民舒适性享受价值3部分；利用物元分析法和替代市场法，建立水资源的价值量和价格计算模型，分析水质、水量、人口自然增长率、人均国内生产总值等指标；以西安浐灞生态区为例，对该生态区的水资源价值进行全面核算。【结果】基于建立的水资源价值量和价格核算模型，对西安浐灞生态区的水资源价值进行分析，结果表明，浐灞生态区的水资源总价值为6.26×103万元，其中自然资源价值、旅游景观价值和居民舒适性享受价值分别为3.60×103，2.65×103和8.96万元，水的自然资源价值最大，其次是旅游景观价值，舒适性享受价值相对较小；水资源价格为2.24元/m3。【结论】用本研究所建模型对西安浐灞区的计算结果与实际基本相符，其对浐灞生态区的水价制定、水资源管理和开发具有一定的指导意义。 |

| Abstract: |
| 【Objective】The quantitative research on value and price for water resources can provide reference for water price formulation and water resources management.【Method】According to the characteristics and functions of the water in landscape,the value of water resources was divided into natural resources value,tourism landscape and recreational value,and matter-element analysis and alternative market methods were used to establish the value and price calculation model,and the index of water quality and quantity,the natural population growth rate,the per capita gross domestic product were analyzed.Taking Chan-Ba ecological zone of Xi’an as an example by establishing water resources value model,the water resources value was accounted comprehensively.【Result】Based on water resources value and price accounting model,analysis of Xi’an Chan-Ba water resources value shows that the total value of water resources in Chan-Ba ecological zone is 62.6 million yuan,including natural resources,tourism landscape and recreational value is 36.0 million,26.5 million and 89.6 thousand yuan respectively.The value of water as natural resources is the largest,followed by the tourism value,and recreational enjoy value is relatively small,the price of water is 2.24 yuan/m3.【Conclusion】The typical survey shows that the calculation result is nearly consistent with the reality,it has the directive significance to a certain extent for water price formulation and water resources management and development in Chan-Ba ecological zone. |
