森林生态学

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。

Dendrology provides students knowledge on trees necessary by forest management, silviculture, ecology, natural reserve conservation and wildlife protection, plant resources and their utilizations. So it is important for students studying forestry to learn knowledge about trees in classification, biological and ecological characteristics.

森林资源管理、退耕还林、林业生态工程、森林保护、植物资源及林产品开发利用等都离不开树木学知识，因此，作为林学的学生必须了解树木的分类、树木的生物学、生态学特性等方面知识，以便为这些课程的学习以及将来的工作提供基础。

Based on the Sino-US Forest Health Cooperation Program, along with review on lots of foreign and domestic literatures, the historical trends of attributes of forest and the concept of health in the modern society are discussed and the concept of forest health is redefined, combining the methods of logic discursion with demonstration analysis, qualitative analysis with quantitative analysis and the ecology with other related science from point view of macro and middle scope aspects.

本研究依托中美森林健康试验示范区建设，结合大量的国内外文献分析，从中观和宏观角度，采用逻辑推理与实证分析、定性分析与定量分析、生态学和其他学科相结合等方法，讨论了森林属性的历史演变和现代健康观，对森林健康进行了重新的定义，首次尝试建立了基于中国林情的森林健康基本理论体系，构建了森林健康的评价方法，结合文献研究对城市森林、农田防护林、马尾松林、笋用雷竹林的健康评价进行了理论验证，并通过江西信丰崇墩沟流域森林健康评价进行了案例分析。

School of forest resources is primarily dedicated to teaching and research forestry resources including agricultural economics, general botany, general zoology, ichthyology, herpetology, genetics, mammalian anatomy, general ecology, environmental science, microbiology, invertebrate zoology, vertebrate physiology, forest hydrology, forest ecology, forest resource economics.

该学院主要致力于林学的教学与科研，学科领域包括农业经济学，普通植物学，普通动物学，鱼类学，爬虫学，遗传学，哺乳动物解剖学，普通生态学，环境科学，微生物学，无脊椎动物学，脊椎动物生理学，森林水文学，林业生态学，森林资源经济学等。

In this text, the natural-ecological sensitiveness appraisal system of Forest Parks in mountain region was set up.

依据生态学和景观生态学的相关理论，筛选出对森林公园规划设计具有重要影响的各层评价指标因子，并确定了评价指标因子的分级标准。

In theory, it is affluent in quantitative analysis of ecological security evaluation, consummate and enrich of system info of silvics.

在理论上，也丰富了生态评价的定量分析方法，完善和充实了森林生态学的理论体系。
