Dynamic Change Analysis Of Forest Resources And Management Countermeasures In Aershan Forest Bureau

Forest is the lung of the earth, is the body of the terrestrial ecosystem. Forest resources is an important part of national natural resources. Is the material basis of forestry and ecological construction is the main object of forest resource management and business activities. Understand and grasp the conditions on the dynamic change of forest resources, can better forest resources management, to achieve forest resource sustainable development, restoration and management of forest resources has very important practical significance and theoretical value.Study is given priority to with forest resources, this paper mainly adopts the comparative analysis and mathematical statistics method, research since 1999, Aershan forestry dynamic change process of forest resources and the reasons of these changes, analyzed the stretch of forest resource management in the field of accumulation, tree species composition, structure, forest age structure and the dynamic change process of forest category structure, find out the favorable factors and restriction factors in the forest resources changes,the research conclusion:Using comparative analysis and mathematical statistics analysis method, research on forest resource dynamic stretching over forestry administration since 1999 and the ebb and flow dynamic change process, the results showed that the varying degrees of imbalance in the structure of forest resources.2.The survey, The administration management area is decreased by 335.7 hm2 than in 1999. forest land, open woodland, shrub and forest planting area, total forestry total volume and forest coverage rate is 402885.8 hm22.82×107m3 and 79.5% respectively. Area than a manager period in 1999 increased by 42646.8 hm2 and stocking volume than last manager period increased by 6.77×106m3, forest coverage period increased by 8.2% by the manager.3.In the forest age structure, mature forest proportion is very small, do not arrange, reasonable rotation, also conducive to the growth of the forest, the proportion of should improve the overripe forest, after waiting for mature forest logging, There is enough young forest, Convert mature.age group structure can be adjusted. Conifer than major, the proportion of broad leaved tree species is low.4. The management countermeasures are presented:(1) to reduce forestry land without a buck in forest and non-forest quantity, improve forest land afforestation, and further increase the forest coverage.(2)Truly stop cutting and cutting in place, strict effectively protect forest resources, to large scale down timber production At the same time do a good job Afforestation work.(3)Innovation, bold practice, and actively promote family ecological forestry construction pace The forest land in quartcl sound partition panel to the contractor Decentralized management, namely the contractor in the contract of forest land to choose its own business activities.
