林业投资研究综述

林业是一项重要的公益事业和基础产业,承担着生态建设和林产品供给的重要任务,做好林业工作意义十分重大。我国林业是一个具有鲜明特点的弱质产业,要实现林业持续稳定增长,需要政策、资金、技术等多因素的合力作用,其中林业投资是关键。文章对我国林业投资的定义、发展阶段进行概括,并对建国以来林业投资研究中采用的方法和取得的成果进行了评述,指出当前林业投资研究中存在的问题,在此基础上对未来我国林业投资的研究方向提出了一些建议。     

试论我国林业投资

我国林业可持续发展中面临着林业投资不足、中央与地方政府的林业投资关系不协调、林业投资结构不合理等问题。通过多样化筹资、调整林业投资布局、协调中央与地方投资关系,加强资金的监管与控制等,可以提高林业投资效率,实现林业可持续发展。

基于林业政策的商品林经营投资收益与投资风险研究

对商品林经营的投资收益率和投资风险进行测定,分析林业政策以及不同因素对投资收益率和投资风险的影响,进而认识林业政策以及不同因素对商品林经营投资的决策行为的影响.分析得出:现有的政策条件还无法改变商品林经营相对投资收益率低、投资风险大的基本状况,对商品林经营的投资还不能产生足够的激励.     

Sustainability assessment for Yanbian forest region, Jilin Province, Northeast China, based on ecological footprint model

Ecological footprint (EF) is one of the most important indicators in assessing the status and capacity of sustainable development. In this paper, the EF of Yanbian forest region, Jilin Province, Northeast China, was calculated and analyzed by statistical yearbooks and forest yearbooks from 1996 to 2002. Results showed that the EF per capita decreased, ecological carrying capacity (ECC) per capita almost kept a static status, and ecological surplus per capita increased year after year. The EF per 10 thousand Yuan GDP per capita in Yanbian decreased from 1996 to 2002. This trend was similar to that in western China, and distinctly higher than that in eastern China. The forest EF per capita kept a steady status, while the forest production footprint (FPF) and forest export footprint (FEF) decreased. Comparing the two years before and after the implementation of Natural Forest Protection Program (NFPP) with the five years, the mean va1ue of FPF and FEF reduced by 0.341 (46.32%) and 0.327 hm² per capita (54.94%), respectively. In conclusion, the regional and forest development in Yanbian was sustainable, and the implementation of NFPP was favorable to improving sustainable development of forest region. However, the sustainability capacity was still lower than those in forest developed countries. Therefore, it is very necessary to improve forest productivity, resource use efficiency and management of forest ecosystems scientifically. __________ Translated from Chinese Journal of Ecology, 2006, 25(2): 129–134 [译自: 生态学杂志]

Prediction and driving factors of forest fire occurrence in Jilin Province,China

Forest fires are natural disasters that can occur suddenly and can be very damaging, burning thousands of square kilometers. Prevention is better than suppression and prediction models of forest fire occurrence have developed from the logistic regression model, the geographical weighted logistic regression model, the Lasso regression model, the random forest model, and the support vector machine model based on historical forest fire data from 2000to 2019 in Jilin Province. The models, along with...     

关于中国吉林省林业建设的思考

This paper reviews various forestry practices in Jilin Province, China. The authors emphasize the rich natural diversity of Jilin and the need to focus research efforts on understanding the potential of native species to meet the needs of land-management agencies involved in forest resource exploitation and ecological restoration. The native species of China hold great potential, and deserve more research attention, for meeting these needs. The introduction and testing of exotic species should be dbne only under rigorous scientific testing and after comparison with native species prior to operational introduction into forestry in order to avoid unwanted ecological consequences, including potential problems with alien invasives and pest introductions. The authors also emphasize the need to maintain viable （e.g., genetically diverse and reproductively fit） natural populations of native species in order to protect China＇s valuable natural diversity and maintain the potential of native species to function as future seed sources for local forest and ecological restoration activities.
