怀柔水库为北京市的重要水源地,水库周边的水源涵养林对水库的水量和水质有巨大的影响。应用影子价格法,对怀柔水库区水源涵养林的生态和经济功能等方面加以货币化评估。通过测算,得出怀柔水库水源涵养林的总价值为1.14亿元。其中环境价值为0.84亿元,占总价值的73%。各价值依大小顺序依次为:涵养水源、生物多样性、固碳制氧转化太阳能、景观游憩、净化环境和保育土壤。根据商品的价值原则,森林生态效益合理的补偿额应该是其生态效益的评估值。从实际情况来看,我国中央森林生态效益现行补偿基金是75元/hm2,北京市现行标准是230元/hm2,与测算出的生态效益评价值年产出平均价值2万3 877元/hm2相比,显然过低。
Huairou Reservoir is an important source of water in Beijing. The water conservation forests around the reservoir have a huge impact on the water quantity and quality of the reservoir. Using the shadow price method, we evaluate the ecological and economic functions of water conservation forests in Huairou Reservoir. Through calculation, it is concluded that the total value of Huairou reservoir water conservation forest is 114 million yuan. Among them, the environmental value is 84 million yuan, accounting for 73% of the total value. The values in order of size are: water conservation, biodiversity, carbon sequestration, conversion of solar energy, landscape recreation, environment purification and conservation of soil. According to the principle of value of commodities, the reasonable compensation amount of ecological benefits of forests should be the evaluation value of its ecological benefits. According to the actual situation, the current compensation fund of central forest ecological benefits in China is 75 yuan / hm2, while the current standard in Beijing is 230 yuan / hm2, and the calculated average annual output value of ecological benefits is 23,877 yuan / hm2 Obviously too low compared to.
