According to the present situations of protected area in China and referring to the definition and category abroad, we suggested the forest natural protected area mainly include three types as follow: Nature Reserves (NR; types of forest eco-system), Forest Parks and Public Welfare Tree Farm. Researches of evaluation on ecotourism resources of forest natural protected area focused on two aspects basically: to appraise and account the ecotourism resources monetarily from the standpoint of pure economics; to assess the exploitability of ecotourism resources based on the theories of conservation biology and ecology, in which finding the reasonable equilibrating point between protection and: utilization was emphasized. On the studies of development pattern of forest ecotourism resources, it is necessary to deal with the relationship between protection and exploitation correctively, namely to put the protection as the first consideration and balance the "Tree r.1ajor Benefits" so that prompting the virtuous circle afforest ecotourism.

根据我国自然保护地的实际情况,参考国外自然保护地的定义与分类方式,可认为我国的森林自然保护地主要应主要包括森林生态系统类型自然保护区、森林公园及公益林场三种类型;森林自然保护地的生态旅游资源评价研究主要集中在两方面:一是单纯地从经济学角度对旅游资源游憩价值进行货币化评价与核算,二是从保护生物学和生态学角度对资源的可开发性进行评价,其侧重在于找到保护与开发的的科学平衡点;在森林自然保护地旅游资源的开发模式研究上,必须正确处理开发与保护的关系,把保护放在第一位,坚持"三大效益"兼顾的原则,才能实现森林生态旅游资源开发与保护的良性循环。

结果表明:在所构建的模型中,除海拔高度与净生产力的相关模型外,其它模型均有较高的实用价值,模型的拟合曲线变化,基本反映了中国森林现实生产力的地理分布格局;中国森林生产力的分布格局主要取决于气候环境中的水热条件,水分条件是决定中国大部分地区森林生产力水平和地理分布格局的主导因素;根据7个GCMs大气环流模型预测合成的2030年的气候情景,研究气候变化对中国森林生产力影响的结果是:气候变化并没有改变中国森林第一性生产力的地理分布格局,即从东南向西北森林生产力递减趋势不变,但不同地域的森林生产力有不同程度的增加。
