基于 GIS 的森林抚育间伐规划设计

摘要

以郏县林场西大坪林区为研究对象，应用 GIS 空间分析的方法，利用 ArcGIS 软件绘制郏县林场林相专题图，对郏县林场西大坪林区内需要森林抚育的林分进行面积总量和空间位置分析，确定相关的规划方案。分析结果表明，郏县林场需要进行抚育间伐的面积为108.8 hm2，地理位置主要分布在林场的中部和西北部。同时证明将 GIS 技术应用到森林抚育间伐工作上，可以有效节约大量人力物力，同时为间伐工作的规划和实施提供决策依据，促进林业全面协调可持续发展。%Took Jiaxian forest farm Xidaping forest region as the research object, used ArcGIS software to draw thematic map of Jiaxian forest form, carried through analysis of total area and spatial position of JiaxianXidaping forest farm which need to forest tending, then identified relevant planning programs.The analysis results showed that the need for Jiaxian forest tending and thinning area of 108.8 hm2, the geographical position was mainly distributed in the central and northwest forest farm;GIS technology could save a lot of manpower and resources if applied to the forest thinning work, and provided decision-making basis for thinning work planning and implementation, promote comprehensive coordinated and sustainable development of forestry.
