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。

During the Last Interglaciation it was the forest, mainly composed of broadleaves, or forest-grassland at the east and middle part of the Chinese Loess Plateau, and was the forest-grassland at the west part of the Chinese Loess Plateau. It changed to the forest or forest-grassland at the most part of the Chinese Loess Plateau in the Holocene, some kinds of hardwood broadleaves dispersing at the warm temperate and the tropic zones appeared. Now the vegetation at the Chinese Loess Plateau inherits from that during the Holocene, the vegetation have been heavily destroyed owing to the human being actions. The vegetation protection at the Chinese Loess Plateau is a significant problem.

末次间冰期期间气候温暖湿润，黄土高原的中、东部地区主要发育了以落叶阔叶林为主的森林或森林草原植被，黄土高原西部地区主要发育的是以针叶林为主森林草原植被；全新世期间黄土高原的植被状况发生较大变化，黄土高原的大部分地区为森林植被或森林草原植被，植被中还有暖温带落叶阔叶林，并含有少量亚热带种属；现代黄土高原的植被主要还是继承了全新世以来的植被状况，但是由于人类活动的加剧，对黄土高原的植被产生了毁灭性的破坏，因此，如何保护黄土高原的自然植被是我们面临的一个严峻的现实问题。
