城市森林保健功能研究进展

随着城市环境问题的日益凸出, 城市居民更加关注环境对自身健康的影响.城市森林是与人类接触最为紧密的森林类型, 也是城市环境中具有重要调节作用的生态系统.文中综合分析了对人类健康起到积极影响的城市森林生态系统服务功能.这些功能大致可以划分为3类:1)改善城市环境的保健功能; 2)调节人类生理、心理状况的保健功能; 3)促进社会属性健康的保健功能.分析结果显示, 影响城市森林保健功能发挥的因素主要包括城市森林的组成和结构、居民的生理和心理状况以及他们的社会经济背景.目前对城市森林保健功能的研究受到缺乏统一的理论基础和有效验证方法的限制.今后研究除应继续加强对各项功能和影响因素的定量化分析外, 重点应放在确立城市森林生态服务和人体健康之间的因果关系上.

Research Progress in Studies of Health Functions of Urban Forests

Classification, investigation and evaluation of forest tourism resources are the basis and prerequisite for the planning and design of forest tourism attractions. The paper reviewed the research progress in the concept evolvement, classification, investigation and assessment of forest tourism resource. The findings showed that the concept evolvement of tourism resource is the objective representation of sightseeing changing from narrow tourism industry to general tourism industry in researchers' understandings of tourism; tourism resources are classified into three categories, i.e., physical attribute, market importance and disciplinary difference; the investigation of tourism resources generally contained geographical location, physical attributes, usage and protection vision; and tourism resources are assessed with hierarchical evaluation method. Finally, the problems in classification, investigation and assessment of forest tourism resources were discussed.
