我国煤炭运输通道优化布局研究

摘要

利用ArcGIS平台，建立中国煤炭供需数据库，构建基于主要煤炭运输铁路、高速公路、国道和基础公路的煤炭运输通道网络，测算省域、县域交通通达度；运用山体水重力模型，以煤炭净存量作为高程值进行分析，得出煤炭供需三维模型的山谷线和山脊线，并结合县域交通通达度和各省域煤炭调动情况，给出我国新建煤炭储备库的煤炭运输通道选址的具体建议。%Applying ArcGIS platform,we made a best route analysis in the coal transportaG tion network of China which was constructed by the main coal transportation railway,highway, national highway and foundational road�Then we also measured the communication availability of all provinces and counties in China� The author got the ridges and valley axes by using the mountain gravity model�Combining the communication availability at county level,we got the fiG nally identified site selections of newlyGbuilt coal transportation corridors and coal storehouse.
