摘要
选择郏县林场为研究区,运用Ar Gis9.3对研究区林相图进行数字化处理,生成DEM模型,应用GIS空间分析的方法,对郏县林场伐区以及楞场位置进行分析,确定规划方案,为森林生态采伐提供方法和现代化技术,从而满足林场生态采伐的需求.分析结果表明,通过GIS缓冲区分析工具对伐区位置和界限进行确定,对楞场进行初步确定.将Arc GIS应用到森林生态采伐工作上,有效地节约了大量人力物力,同时为生态采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.
Selecting Jiaxian forest farm as study area,using the ArGis9.3 to digitize the stock map in the study area,generating DEM model,with application of GIS spatial analysis method,we analyzed the Jiaxian forest cutting area andstare blankly field position,determined the planning scheme,and provided methods and modern technology forforest ecological harvesting,so as to meet the needs of forestry ecological logging. Analysis results show that through theGIS buffer analysis tool the cutting area location and boundaries are determined,and the stare blankly field is determinedpreliminarily. Appling ArcGIS to forest ecological harvesting work,can save a large amount of manpower materialresources effectively,and at the same time provide decision basis of the planning and implementation for ecologicalcutting work,and promote the comprehensive,balanced and sustainable development of forestry.
