The Dynamic Analysis On Forest Resources After The Implementation Of NFPP In Banfanggou Forest Farm In Xinjiang

The dynamic process of forestry land area,the forest area and volume of forest types,forest age groups,and forest stock volume per unit area of each age group forest and each forest type,forest harvested volume and forest resources being harvested were analyzed in the paper on basis of collecting forest survey data and annual survey of updated data in 1990,2009,2014,and the third phase of and the local natural environment,ecological environment construction and other information in BanFangGou forest farm in Xinjiang.The result show that,in 20 years by using GIS investigation and other ways to redistricting scope forest farm and forestry land area changes.According to a 2014 survey statistics,forest land area of 74030.96hm2,among them:the arbor forest land 27788.97 hm2,opening 1144.02 hm2and 26433.89 hm2 shrubbery,nursery 10.65 hm2,around 18653.43 hm2.standing timber total of 3981981.77 m3,of which:forestland accumulation of 3881122.17 m3,the opening forest land is of 100859.6 m3.After 17 years of natural forest protection project,In forest farm BanFangGou the acreage and the stand volume of the young forest and immature timber were all increased to different extents.The quality and quantity of near-mature forest presents the obvious increasing trend,the acreage and the stand volume of the mature forest and overmature forest are also increased to different extent.The good new is that,the forest forest quality improved obviously in forest farm BanFangGou,Specific performance in the forest stock volume per unit area from 1990 to 2014 increased by 13.3 m3,stand volume of unit area overall reached the level of 137.6 m3/hm2.The increase of the forest resources,mainly because since 2000 the Natural Forest Resource Protection Project was fully implemented which attach importance to the management of forest resources and forest management work,to improve the quality of the ecological public welfare forest.To the change of volume per unit area from each age group,young forest volume,the unit of mid-maturation forest and ripe forest area reduced 8.7 m3,respectively,8.7 m3 and 3.7 m3.Only nearly ripe forest and mature forest stock volume per unit area were increased by 1.5 m3 and 1.5 m3,but also has the very big growth space,therefore we should strengthen young,mid-maturation forest tending,take reasonable tending and management measures,accelerate the growth of trees,improve the quality of the forest.In addition to reasonable cutting,and constantly adjust the structure of forest stand,shorten the breeding period,in order to realize the sustainable utilization of the forest.
