Based on the policy background of “stop cutting” in 2014,this paper analyzes the dilemma which the state-owned forest area is facing with in Daxing'anling of Heilongjiang Province and the difficulties in finding out the outlets for forestry enterprises. In the area,the forestry industrial structure is imbalanced,the livelihood of some forestry residents is in trouble,the increased financial pressure,the difficulty of personnel training increased,the level of infrastructure is difficult to adapt to the transformation,and so on.At the same time,combined with the actual situation of the state-owned forest,the paper put forward some suggestions:to advance the reform of management system in state-owned forest areas,to integrate the timber processing enterprises,to establish the support policy system,to improve people's livelihood and attract outstanding talents.

Based on Chinese Fir Growth Model and the improved model of Faustmann-Hartman,Chinese fir in Jiangxi Province was taken for the research object to compare LEV and optimal rotation period of Chinese fir under different sites,different carbon prices and different interest rates.The results show that due to the current wood prices far higher than the price of carbon sinks,composite target under the carbon sink forest management does not change the Chinese fir optimal rotation period and the carbon price does not affect Chinese fir optimal rotation obviously,and the interest rates and Cunninghamialanceolata optimal rotation turn into negative correlation.At the same time,the expected value of Chinese fir forest based on carbon sink management is larger than that of single objective,and the expected value of forest land is increasing rapidly,which means that the investment management of carbon sink forest can be considered in the process of forest management.

Based on the geo-statistical theory,data of observation samples are used to fit the optimal variation function model and analyze spatial pattern of Picea Schrenkiana site index in the forest farm of Xinjiang Agriculture University.The results show that the frequency distribution of the site index of Picea Schrenkiana gets close to a normal distribution and has moderate degree spatial autocorrelations.After comparing the estimated results with actual results,the spherical models are confirmed with high accuracy.Picea Schrenkiana site index predictions with the ordinary kriging method are more accurate than those obtained by using inverse distance weighting.Consequently,we identify geostatistical analysis as a promising technique to map complex patterns of Picea Schrenkiana site index and suggest that it should be added to the toolbox of forest practitioners.

From the four aspects of the personnel,the equipment,the logistical support and the fire fighting ability and by using the intuitionistic fuzzy sets and the TOPSIS method,firstly the evaluation index system of forest fire prevention service scheme is established. Secondly,the analytic hierarchy process(AHP) and Delphi method are used to calculate the weight of the index,then the intuitionistic fuzzy evaluation matrix constructed,the positive and negative ideal solutions established and the distance of the alternatives to the positive and negative ideal solutions calculated. Finally,the comprehensive evaluation indexes are calculated,and the ranking of the fire service program effectiveness obtained. The Baritu Forest Farm at Hulunbeir of Inner Mongolia has been taken as an example for verification.
