崂山森林生态系统服务功能及其价值评估

Laoshan Forest Ecosystem Service Function and Its Value Evaluation

森林生态系统在带来经济价值的同时,也带来了巨大的生态价值。我国经济在不断发展,随着人民生活水平的提升,对森林生态系统的生态效益日益关注。本文以崂山森林生态系统为研究对象,采用市场价值、影子工程、替代花费等方法从涵养水源、保育土壤、制氧固碳、净化环境、森林休憩和提供林木产品等6个方面对崂山风景区森林生态系统的生态服务功能进行了一般评估,结果得出:崂山风景区森林生态系统每年的生态服务价值量为16580.2万元,以制氧固碳、旅游休憩功能为主,旅游业所带来的经济价值比重较大;但在涵养水源、保育土壤、净化环境方面比重较小,应加强人为管理。

The forest ecosystem brings economic value as well as great ecological value.With the continuous development of China’s economy and with the improvement of people’s living standard,the ecological benefits of forest ecosystem are becoming more and more concerned.This paper takes the Laoshan forest ecosystem as the research object,and uses market value,shadow engineering,and alternative cost methods to improve the Laoshan Scenic Area from six aspects,including water conservation,soil conservation,oxygen production and carbon fixation,environmental purification,forest rest,and provision of forest products.A general assessment of the ecological service functions of the forest ecosystem has been carried out,and the annual ecological service value of the forest ecosystem in the Laoshan Scenic Area is 165.802 million yuan.It is mainly based on the functions of oxygen and carbon fixation,tourism and rest.The proportion is larger.The proportion of water conservation,soil conservation and environmental protection is relatively small,and human management should be strengthened.
