摘　　要："中缅油气管道"是我国陆上第三大能源通道,该项目的建设将改变其沿线周边的土地利用/覆盖现状,同时对沿线地区的自然环境和社会经济发展产生重要影响。本文选取中缅油气管道沿线的国内11个重要节点和缅甸境内4个重要节点作为研究区,以2012年和2015年2期Landsat7 ETM+和Landsat8 OLI影像数据作为数据源,利用决策树分类算法提取2012年和2015年2期中缅油气管道沿线重要节点的土地利用/覆被信息,分析2012年和2015年2个时期的中缅油气管道沿线15个重要节点土地利用/覆被的时空变化。研究结果表明:(1)15个节点中,除德宏芒市、保山隆阳区、缅甸若开邦外,其他11个节点的土地覆被变化均在20%左右;(2)15个节点中,最主要的土地覆被变化为植被和裸土的相互转换,其次为其他土地覆被类型向建筑的转换;(3)由于中缅油气管道项目的辐射作用,带动当地经济发展,改变当地的经济作物结构,因此造成大量的植被和裸土的相互转换,并造成建筑用地需求增加,出现大量的其他地表覆被类型向建筑的转换。＂China-Myanmar oil and gas pipeline＂ is the third largest land energy corridor in China.The construction of this project will change the status of land use/cover around the line, and at the same time,it will have an important impact on the natural environment and social and economic development of the region along the line.Selecting the 11 important nodes at home and 4 important nodes in Burma along the China-Burma oil and gas pipeline as the study area,and based on Landsat7 ETM＋and Landsat8 OLI image from 2012 to 2015,using the decision tree classification algorithm to extract the land use/cover information of the important node along the in China-Burma oil and gas pipeline from 2012 to 2015 and analyzing the land use/cover change of 15 important nodes along the China- Burma oil and gas pipeline during 2012 and 2015.The results show that ：（1）The land cover change of 15 nodes was about 20% excluding the Mangshi city, Longyang district, Rakhaing State;（2）The main land cover change is the conversion between vegetation and bare soil, and the other change is the conversion between other land cover to construction;（3）The China-Burma oil and gas pipeline projects has radiating drive effect on promoting the development of local economy, and changing the economic structure of the local crop, and resulting in a large number of conversion between vegetation and bare soil, and causing the increase of building land demand and the emergence of a large number of other land cover type conversion to buildings.
