摘要:
[目的]评估城市森林生态系统服务功能价值,为城市生态环境持续改善和经济发展提供科学依据和理论支持。[方法]选用河北省秦皇岛市北戴河区森林生态系统作为研究对象,采用水量平衡法、替代工程法、机会成本法、生产成本法、碳税法、市场价值法、认购意愿法等,对森林生态系统提供的涵养水源、保育土壤、固碳释氧、净化大气、森林防护、游憩休闲等6种服务功能价值进行评估。[结果]北戴河区森林生态系统服务功能价值达到14.87亿元/a。其中,游憩休闲功能价值居首位,达到10.87亿元/a,约占总价值的73.12%。各项森林生态系统服务功能价值表现为:游憩休闲 > 净化大气 > 涵养水源 > 固碳释氧 > 保育土壤 > 森林防护。[结论]森林生态系统在城市生态系统中发挥着重要作用,尤其是旅游业的发展能够很好地拉动北戴河区经济的发展,有助于合理利用与经营北戴河区森林资源,最终实现北戴河区森林资源的可持续利用。

Abstract:
[Objective] To evaluate the value of urban forest ecosystem service function in order to provide scientific basis and theoretical support for the continuous improvement of urban ecological environment and economic development.[Methods] Forest ecosystem of Beidaihe District of Qihuangdao City was chosen as the research object. Water balance, alternative engineering, opportunity cost, production cost, carbon tax, market value and subscription intention methods were adopted to evaluate the service function of forests ecosystem including soil and water conservation, carbon fixation and oxygen release, air purification, forest protection and recreation and leisure.[Results] The service function value of forest ecosystem in Beidaihe reached to 1.487 billion Yuan/a. Among them, function value of recreation and leisure ranked first, reached to 1.087 billion Yuan/a, accounted for 73.12% of the total value. The service function value of various forest ecosystem ranked as:leisure recreation > purification of atmosphere > water conservation > carbon fixation and oxygen release > soil conservation > forest protection.[Conclusion] Forest ecosystem plays an important role in urban ecosystems. In particular, the development of tourism can promote the development of economic development in Beidaihe District. To use and manage the forest resources rationally, the sustainable development of forest resources in Beidaihe District will be realized ultimately.
