摘要

根据水利生态效益的特点,运用市场价值法和人力成本法,从水土保持、水质改善、饮水安全3个方面量化水利生态效益,测算1990—2015年全国、陕西省、江苏省的水利生态效益。结果表明,虽然我国水利生态效益总体上升,但效益值仍然偏低,各地区水利生态面临的主要问题不尽相同,需进一步加强水利生态的投资和建设,因地制宜,解决各地主要生态问题。
        According to the characteristics of ecological benefits of water resources,the market value method and human cost method are selected to quantify the ecological benefits of water resources from three aspects: soil and water conservation,water quality improvement and drinking water safety. The ecologicalbenefits of water resources in China from 1990 to 2015 as well as those in Shaanxi and Jiangsu provinces are estimated. The results show that the ecological benefits of water resources in China generally increase,but compared with the economic benefits of water resources,the proportion is still low. The main problems faced by the ecology of water resources in different regions are also different. It is necessary to further strengthen the investment and construction of the ecological benefits of water resources. At the same time,measures should be taken according to the local conditions to solve the main problems in various areas.
