Investigation and Analysis of Forest Growth in Mountainous and Hilly Areas of Bayannur City
Based on the data of forest resources planning and design investigation and special investigation in Bayannur City,the forest growth,unit area growth and growth rate in mountainous and hilly areas of Bayannur City were calculated.The annual growth of forest standing trees in Bayannur mountainous and hilly area was 32 925.56 m3,the unit area growth was 0.46 m3/hm2,and the growth rate was 1.55%.This paper makes an in-depth analysis of Arbor woodland from five aspects:dominant tree species,origin,age group,canopy density and status class,in order to better understand the growth process,present situation and trend of Arbor forest,grasp its accumulation dynamic change in time,and predict its growth trend to provide a theoretical basis for scientific and rational forest management planning.
