Optimization Approach of Coal Transport Network Between Yunnan-guizhou Base and Guangdong-Guangxi
研究了云贵煤炭基地与广东、广西的供需矛盾，分析了现有运输网络的问题，并提出了以铁水联运、河河联运和铁路运输为主的优化方案。
Guizhou and Yunnan are the important coal production bases,and their adjacent Guangdong and Guangxi provinces are the important economic regions and coal-poor reigons.Especially,Guangdong has the increasing demand of coal consumption.Therefore,the coal transportation becomes the key issue that two regions must slove together.In this paper,we disussed the spatial pattern of coal resources in Yunnan-Guizhou base and its trend of coal output,and the developing trend of coal consumption in Guangdong and Guangxi,which reveal the contradiction between the supply and requirement in Southwest China and South China.Furthermore,we analyze the primary features and existing problems of the coal transport network between Guizhou-Yunnan base and Guangdong,Guangxi provinces,and forecast the trend of coal supply and demand and new contradiction among the coal production,industrial regulation and energy utilization mode.Finally,we propose the optimization planning of coal transport network from Guizhou-Yunnan base to Guangdong-Guangxi region,and consider that rail-river combined system,river-river combined system and rail transportation are the main approaches to support the coal supply.
