天保工程实施六年来，工程取得了一定成效。然而在天保地区森林资源保护与社会经济发展之间仍存在很多问题。为此，应建立森林生态效益补偿机制，发行绿色生态彩票，对林业项目实行贴息贷款等投资渠道在内的天保工程资金投入机制。同时，给予天保地区经济发展贷款优惠政策，加强区域间投资合作，推行小额信用贷款款等措施。建立天保地区社区经济发展的资金投入机制，以实现天保地区森林资源保护与社会经济的协调发展。

Forest, as the main body of the terrestrial ecological system and the important natural resource on which the mankind relies for subsistence, not only can provide timber and other forest products, but also has the function of adjusting climate, conserving water and soil, wind-breaking and fixing sand, etc. It plays an irreplaceable role in maintaining the natural ecological environment. Since 1978, the open-door and reform policy has been carried out in China, the Chinese economy has been developing very fast. At the same time, Chinese government has given priority to tree planting and forestry development which are seen as significant contributors to the development of the ecological environment The upsurge of tree planting and forest protecting have been set off one after another by organizing and mobilizing the people all over the China Remarkable work has been done to develop forestry and improve the landscape of the country. In this paper, the development of forestry in the last 20 years has been reviewed and major forestry policies have been discussed.Based on the development of national economoy and forestry situation, the 4 major strategy measures have been pointed out for the developemnt of forestry in the future.

Based on the current conditions, a forecast of trends in imports and exports of wood products and their demand and supply is presented in this paper for the years of 2005 and 2015. It is expected that imports will continue to exceed exports but that the trade deficit in wood products will decline. The form of trade will be changed from a condition of unilateral imports to one of exerting mutual advantage through imports and exports. The structure of trade in forest products will alter with changes in the forest source base and with new developments in the forest industry.

For predictive purposes and for understanding the re1ationship between the US market and Canadian newsprint producers an econometric model was bui1t. In this study, a simu1taneous-equation model was developed. Which consisted of four equations, one each for the supply, export, consumption and price of newsprint. The period of l955-1986 was covered by this mode1. The data for the years l985 and l986 were reserved to test the predictive, power of the model. In fitting the four equations for the period of 1955-1984.the coefficients of determination, the R-square values, between observed and predicted values were higher than 99 percent. The test results of the forecasting power showed that there was no statistically significant difference between predicted and observed values at the 5 percent level of significance. Sources of forecasting error are expressed as three partial inequality coefficients associated with bias, variance and covariance of predicted and observed values. The error could not be further reduced. The model can be used to make annual predictions and provides an accurate means of predicting demand, supply, consumption and price of Canadian newsprint exports to the United States of America.

在我国全面建设小康社会、加快推进社会主义现代化建设的历史时期，大力培育和发展非公有制林业有利于推进林业经济结构的战略性调整，优化森林资源配置，扩大造林面积，更好地满足社会经济发展对生态环境和林产品的需求，实现林业的可持续发展。长期以来我国的非公有制林业发展严重滞后，与之相关的法律政策措施也不完善，制约了非公有制林业的发展。与世界上私有林较为发达的国家相比，影响我国非公有制林业发展的主要因素是法律和政府的扶持政策不完善、执行不到位。为了加快发展我国的非公有制林业，必须完善相关的法律法规，依法治林，保障经营者的林权不受侵犯，同时对非公有制林业经营者实行税收、信贷、项目补贴、科技服务和社会服务等多方面优惠政策，保证非公有制林业经营者能够从林业投资中取得合理的汇报率，从而调动全社会各方面的力量发展我国的林业建设事业。

运行机制的合理与否直接关系到天然林保护工程的效果，本文从天保工程的管理机制和各工程实施单位的具体运行机制两个层面来阐述天保工程的运行机制，提出目前运行机制存在的问题，并引入诸学者对天保工程运行机制的研究论点，最后，笔者提出了应建立起天保工程资源保护与社会经济协调发展运行机制的意见。

该文系统地回顾和总结了80年代以来我国林业产值领域的研究历程及其得的研究成果，指出目前研究的重点是探索建立以增加值为核心的林业产值指标体系和科学系和合理的核算方法，以真实地反映林业的生产成果。

该文利用计量经济学方法对改革开入以来中国森林覆盖率变动的因素进行了了分析，对中国大陆的30个省区按照东部、中部和西部的行政区划，分别考察了森林覆盖率的影响因素及程度。同时对我国林业今后的战略发展提出了建议。
