浙江淳安县竹林生态服务价值评估研究

竹林具有减少土壤损失、涵养水源、释放负氧离子、固碳释氧等多种生态功能。用生态经济学原理与方法对浙江淳安县竹林的部分生态服务价值进行了评估。结果表明:淳安县竹林生态服务总价值为5.94亿元,每公顷竹林的生态服务价值为4.07万元;在生态服务总价值中,固碳释氧服务价值所占比重最大,为89.79%;其次为涵养水源服务价值,占9.52%。可见,竹林生态服务价值主要体现在改善环境质量和涵养水源方面。研究结果可以为货币化竹林生态服务提供借鉴。

Evaluation for Ecosystem Service Value of Bamboo Forest in Chun'an County

Bamboo forest with a variety of ecological functions, such as reducing the loss of land resources, water conservation, releasing of negative oxygen ions, carbon fixation and release oxygen, this paper applied the ecological economics principle and the method to assess the bamboo forest ecological services valuation of Chun'an county. The results showed that the total ecological services value of Chun'an bamboo forest is up to 594 million yuan per year, which per ha value of 4. 07 million yuan. In the total value of ecological services, the value of carbon fixation and oxygen release service accounted for the largest proportion, which was 89. 79%, and the second is the value of water conservation service, accounting for 9. 52%. Therefore, the ecological service value of bamboo forest is mainly reflected in the improvement of environmental quality and water conservation. The research results can provide reference for monetizing ecological service of the bamboo forest.
