Influence of forest fire disaster on forest ecosystem in great xing ' anling
大興安嶺森林火災對森林生態系統的影響In this dissertation a typical area was selected as a case study, which is the tuqiang forest bureau, including two forestry farms, namely, yuying and fendou, covering more than 1. 2 10s ha, it is also one of the most severely burned bureaus during this fire. based on the widely investigation of the background information in the study area, and supported by the geographic information system ( gis ) and remote sensing ( rs ), the two digital forest stand maps ( 1987 and 2000 ) and dtm data were overlaid and the spatial and attribute database were produced. according to this, basic characteristics and changing of landscape structure and spatial pattern were widely and thoroughly analysed
論文選擇位於大興安嶺北坡圖強林業局的育英和奮斗兩個林場作為研究區(該區是1987年重過火區,總面積12萬多ha ) ,在對研究區基本情況廣泛調查的基礎上,藉助于rs 、 gis技術手段,並輔以景觀生態學知識的支持,研究了林火跡地森林景觀格局及其變化的主要特徵,同時運用分佈指數、偏相關分析等方法重點探討了地形因子對格局及變化的影響。First, the theoretical regimes have been set up to meet the demand of forest resource sustainable management, and to make entironment conserve, economic development and resource utilizing come into harmony
