水环境质量资源定价模型研究

Study on pricing model of aquatic environment quality resources

在水环境质量资源的价格分析中,引入"级差地租"理论,以水质差异而造成的水价不同作为水环境质量资源的定量依据,结合模糊综合评判法,建立一种新的适用于复杂且模糊的多指标评价体系的环境质量资源定价方法。以广州流溪河为例,分析了各河段的水质价格,分析表明,本文提供的模型可为合理调整水价,修正水资源核算,制定水资源管理的相关政策提供依据。

Using price difference caused by water quality difference as the quantifying base of water environmental quality, introducing differential rent theory and combining with fuzzy comprehensive evaluation, a pricing method of aquatic environment quality resources was proposed. This new pricing method was applicable to complicated and fuzzy multi-index evaluation system. Taking Liuxi River in Guangzhou as an example, water quality price in each river section was calculated, which provided a base for rationally adjusting water price, correcting water resources checking and making relevant police of water resources management.
