【摘要】 林业运输线路优化是林业物流和林业企业木材生产流程中重要部分。以吉林省汪清林区为研究区,基于网络最短路径模型和GIS、RS技术以及伐区、集材和运材等环节约束条件,构建伐区运输线路优化模型,确定伐区木材运输最优线路,并对选取的运输线路进行综合实证分析。更多还原

【Abstract】 The route optimization for transporting timber in forest is an important part of timber production processes for forestry logistics and enterprises.Wangqing forest area in Jilin province was taken as the research district in this paper.Based on shortest path model,GIS(Geographic Information System) and RS(Remote Sensing) technology as well as all the constraints linked to timber harvesting such as cutting area,skidding and timber transportation,the optimized model of transportation routes in harvesting site was established.The best route for timber transportation was determined and comprehensively analyzed.更多还原
