大兴安岭林业持续发展的探讨

大兴安岭森林是受冻土控制下形成和发展的，保存了大量淡水资源，形成了冷湿生态环境。大兴安岭林业持续发展必须按特殊方式经营，建立生态林业，从而发挥其固有的多种效益。     

The amenity value of woodland in Great Britain: A comparison of economic estimates

Forests produce benefits over and above the revenue yielded from timber and other wood based products. Most important among these may be the recreational benefits for visitors, which have been examined in several studies. Total benefits for residents are perhaps more accurately captured in property values since, ceteris paribus, the price of a house reflects willingness to pay to live near an environmental amenity such as a forest to gain access to it, and also the amenity (non-use) value of the forest in so far as it creates a pleasant landscape. However, the total non-priced value of forestry is not the sum of HPM and ITCM benefit estimates. Recreational benefits will typically be less, and will be subsumed in the HPM estimates, since the hedonic price is partly induced by the value of recreational access.

Wood Fuel or Carbon Sink? Aspects of Forestry in the Climate Question

This paper discusses and contrasts two mainroles of forestry in light of the debate on theglobal climate. As the main problem is relatedto the increases of the CO₂-concentrationin the atmosphere, forests may be viewed aspart of the alleviation of the problem throughtheir function as (i) a source of biomass forenergy production, which may replace fossilfuels and thus indirectly reduceCO₂-emissions, and as (ii) carbon storage,since a growing forest extracts atmosphericCO₂ and fixes it as carbon in biomass. Inthe Scandinavian forestry, logging residues areincreasingly being used for energy production.In this paper the value of forests as a sourceof bioenergy is added to the traditional timbervalue. Formulated as a joint production modelwithin the Faustmann framework, the effect ofthis addition on the optimal rotation length isdiscussed. Based on data for spruce, thedominant species in the Scandinavian forestry,it is demonstrated that the rotation length isshortened compared to the standard Faustmannmodel. Shorter rotation length implies lesscarbon storage. Therefore, in this modelwithout explicit regard to the social carbonstorage value of the forest, the gains in termsof the climate problem from utilisation offorest biomass for energy production are beingdiminished by the value of reduced carbonstorage. The carbon value of the forest is thenadded to complete the model, with the effect ofincreasing the rotation length, a result thatis well known in the literature. Finally, theempirical effects of the interaction of thesetwo climate-related value elements of theforest are discussed.     

Multiple Species Boreal Forests – What Faustmann Missed

Recent research in natural sciences shows that the dynamics in boreal forests are much more complex than what many models traditionally used in forestry economics reflect. This essay analyzes some challenges of accounting for such complexity. It shows that the optimal harvesting strategy for forest owners is history dependent and for some states of the forest, more than one strategy may be optimal.This paper confirms earlier literature on shallow lakes and coral reefs and shows that this kind of phenomena seem much more common than previously thought. They are valid for a wide range of ecosystems that cover large surfaces and they do not depend on the choice of some specific function to model the non-linearity. There are also indications that theses results could be obtained even for resources with concave growth if at least one species with non-linear growth affects their dynamics.

现代林业与生态经济林业理论和实践

试述现代林业的含义;浅释生态经济林业理论与推进现代林业建设的意义;通过分析中国森林生产力状况提出存在的矛盾,试论发展林业的主战场、由中央直接管理全国林业企业局、和建立集约化经营森林的制度与措施等发展森林生产力的意见。     

现代林业集约化森林经营的思考

实行森林经营集约化是缓解森林资源危机的科学途径;反思林业机构设置对现代林业建设的影响;提出森林经营的关键在于把林况和经营措施落实到山头地块,编好和严格执行森林经营方案;小班林木经营的好坏,决定集约化森林经营的成败。     

从闽台林业比较看合作的优先领域

通过对比闽台林业发展的异同,认为台湾林业在技术、管理和资金上存在优势;福建在自然资源和劳动力等方面存在优势。两省林业合作符合区域合作的比较优势理论、产品周期理论和林业可持续发展理论,应优先发展林业高新技术产业、林业科研与教育、森林文化与森林旅游、林业资源管理、林业共同市场和城市林业等领域。政府在产业布局、资源利用、基础设施建设、文化建设等方面须加强管理,以规避合作的经济风险和生态风险,促进闽台林业合作顺利有序发展。
