利用1990 - 2010年老挝磨丁边境开放以来的Landsat TM/ETM+影像，分析了老挝北方琅南塔省土地利用/土地覆盖的时空变化。结果表明：（1）“林地-耕地-草地”为主要景观结构。2010年，林地是主要的土地覆盖类型，水田是主要的土地利用类型，橡胶种植园取代了水田;（2）自1994年边境口岸开放以来，土地利用变化的速度和强度逐渐加快，尤其是近10年来。林地减少明显，灌木林、橡胶种植园和撂荒地增加明显。林地和灌木林地中橡胶种植园和刀耕火种增长最快，说明人类活动和刀耕火种持续存在;（3）1990-2010年，刀耕火种主要分布在北方山区，且近10年来空间分布变化频繁。橡胶种植园主要分布在中老边境地区，并以琅南塔市为中心，由边境地区向非边境地区扩展。昆明-曼谷高速公路沿线林地减少沿着十分明显。
Spatial-temporal changes of land use and land cover in Luang Namtha Province in northern part of Laos was analyzed using Landsat TM (Thematic Mapper)/ETM+ (Enhanced Thematic Mapper) images from 1990 to 2010 since the opening of the Boten border adjacent to China. The results showed that: (1) “forest land—cultivated land—grassland” was the primary landscape structure. Woodland was the major land cover type, while paddy field was the dominant land use type replaced by rubber plantation in 2010; (2) since the opening of the border crossings in 1994, the rate and intensity of land use change were accelerated and enhanced gradually, especially in the recent decade. Woodland decreased significantly, while shrubland, rubber plantation and swidden land increased obviously. Rubber plantation and swidden land showed the fastest growth derived from woodland and shrubland, indicating continuous human activities and slash-and-burn farming; and (3) during 1990–2010, swidden land was mainly located in northern mountainous areas with frequently increased changing spatial distribution in the recent decade. Rubber plantation was mainly distributed in the border region of China and Laos with the expansion from the border region into the non-frontier of Laos with Luang Namtha City as the center. Woodland reduction was so obvious along the Kunming-Bangkok highway.
