黄金经济四边形区域位于中、老、缅、泰四国交界处，是澜沧江-湄公河流域唯一的多民族地缘经济区域，随着各种经济合作机制的发展，该区域正成为土地利用/土地覆盖变化的热点和脆弱区，研究发现，目前对土地利用/土地覆盖变化的研究相对分散和零散，土地利用/土地覆被变化分类与制图的研究大多来自全球性的大尺度工作，不能满足区域时空研究的需要，高分辨率的区域分类与制图研究较少。土地利用/土地覆被变化的格局与过程分析更多地关注于特定的土地类型，土地利用/土地覆被变化的驱动力研究仅限于小范围的局部区域，而对土地利用/土地覆被变化的影响研究则较为丰富，土地利用/土地覆被变化对土壤环境的影响研究较多，对水、大气、生态环境的影响研究较少，建议加强不同时空尺度的比较研究，扩大研究主题，采用综合方法，同时，加强对边疆地区和欠发达地区的研究，开展中、老、缅、泰四国边境地区土地利用/土地覆被变化的国别比较研究，不仅有助于丰富四国边境地区土地利用/土地覆被变化基础数据库，而且可为四国边境地区土地可持续利用和区域发展提供参考。
Golden Economic Quadrangle Region is located on the borders of China,Laos,Myanmar and Thailand,the only multi-national geo-economic region in the Lancang-Mekong River Basin.With the development of various economic cooperation mechanisms,this region is becoming a hot and vulnerable area of land use and land cover change.The study has found that the current researches on land use and land cover change are relatively scattered and dispersed,lacking of holistic,comprehensive and regional comparative studies.Most data of land use and land cover change classification and mapping are from global and large-scale works,which can’t satisfy the regional research needs from the spatial and temporal perspectives.There have been only few high-resolution regional classifications and mapping studies.The levels of the studies on particular land types,i.e.,opium poppy,swidden land,rubber forest,vary.Especially,the remote sensing recognition method and spatial-temporal analysis are inadequate.Pattern and process analysis of land use and land cover change has paid more attention to certain land types,but less attention to integrated and national comparative studies.Studies on driving forces of land use and land cover change are only carried out in small local areas.There are abundant studies on the effects of land use and land cover change on soil environment,but relatively rare on water,atmosphere,and eco-environment.The paper suggests that it is necessary to emphasize on comparative studies in different spatial and temporal scales,expand the research topics,adopt comprehensive methodologies,and at the same time,put more focus on the studies in the border regions and underdeveloped areas.The inter-national comparative studies on land use and land cover change on the borders of China,Laos,Myanmar and Thailand,not only help enrich the basic database of land use and land cover change,but also provide references for sustainable land use and regional development on the borders of the four countries.
