基于GIS的昆侖山林場森林資源分類區劃研究

摘 要:文章以昆侖山林場最新森林資源調查資料為依據，并結合昆侖山林場的地形、地勢特征，通過GIS技術，對研究區的森林資源進行補充調查區劃。利用ERDAS IMAGINE 8.6、ArcGIS 9等軟件強大的空間分析和數據管理功能。對昆侖山林場的SPOT遙感影像以及矢量數據進行處理，分析得出昆侖山林場的森林資源分布現狀，并對其進行合理區劃。經過統計分析該林場公益林總面積為64166.87hm2，其中:有林地面積為15372.8hm2，占公益林總面積的23.95%;疏林地面積為12971.33hm2，占公益林總面積的20.22%;灌木林地面積為35708.47hm2，占公益林總面積的55.65%;宜林地面積為114.27hm2，占公益林總面積的0.18%。

Abstract:This article take the newest forest resources investigation materials as the basis which are in the tree farm of Kunlun Mountain.And unifies the terrain and topography characteristics that in the tree farm of Kunlun Mountain.This carry on the supplement investigation regionalization for the forest resources studies through the GIS technology.Using ERDAS IMAGINE 8.6 and ArcGIS 9 for formidable spatial analysis and data management function.Processing the SPOT remote sensing image that in the tree farm of Kunlun Mountain as well as the vector data.Analysis the forest resources distribution in present situation which in the tree farm of Kunlun Mountain，and carries on the reasonable regionalization to it.After the statistical analysis，the total area of public welfare forest is 64166.8 hm2，including the forest land area 15372.8 hm2，accounts for 23.95% in the total of the public welfare forest area;the open woodland area 12971.33 hm2，accounting for 20.22% in the total of the public welfare forest area;the bush forest land 35708.47 hm2，accounting for 55.65% in the total of the public welfare forest area;the area suitable for forestation 114.27hm2，accounting for 0.18% in the total of the public welfare forest area.

GIS(Geographic Information System)是在計算機支持下管理、處理、分析包括不同來源和形式的遙感數據、地形圖數據、專題圖數據、野外采樣數據、統計調查數據等等的信息系統[1]。在森林資源分類區劃界定中，為了準確地掌握森林資源的空間分布狀況，提高森林資源的分類區劃精度，采用GIS技術可以合理的對森林資源進行區劃界定。
