河南省森林公园生态系统服务功能价值评估

摘要

To provide scientific basis for the construction of the forest park ecosystem in Henan Province,China, the quantitative method was used to evaluate the forest park ecosystem services. The vegetations of the forest park ecosystem in Henan were confirmed as temperate and subtropical deciduous broadleaved forests. The appropriate evaluation methods were used in different ecosystem services. And the total value of the forest park ecosystem services in Henan was 68.55×108 yuan(RMB), of which the direct economi cvalue was 10.5×108 yuan, and the indirect was 58.05×108 yuan. The latter was 5.53 times of the for-mer. In all kinds of the service values, the value of water source conservation was the highest, accounting for 46.8% of the total. The second was the value of fixing carbon and making oxygen which occupied 16.3% of the total. The recreation value occupied 15.3% of the total. It indicated that the main services of the forest park ecosystem were water source conservation, air-conditioning and leisure & recreation.Meanwhile, the value of air purification and biodiversity conservation was remarkable. The forest resource is very deficient in this province, and the forest park is much more precious. In Henan Province, based on careful protection, the forest park should be actively constructed to protect ecological environment and sat-isfy the public recreation.%采用定量方法评估河南省森林公园的生态系统服务功能价值,为河南省森林公园建设提供依据.确定河南省森林公园植被属温带、亚热带落叶阔叶林类型,参考前人研究成果和统计年鉴数据,进而确定河南省森林公园生态系统服务总价值.结果表明河南省森林公园生态系统服务功能的总价值达68.55×108元.在河南省森林公园生态系统服务价值中,直接经济价值为10.5×108元,间接经济价值为58.05×108元,是直接经济价值的5.53倍.在各类服务功能价值中,涵养水源价值最高,占生态系统服务价值总值的46.8%,其次是固碳放氧价值,占总价值的16.3%,游憩价值占总值的15.3%.说明森林公园在水土保持、空气调节和休闲娱乐上的作用是极其重要的.林木产品价值、净化空气价值、生物多样性价值也较为显著.河南省森林资源较为贫乏,森林公园资源更加珍贵.应该在加强河南省森林资源保护的基础上,积极进行森林公园建设以保护生态环境和满足公众游憩.
