山体滑坡是泰国南部花岗岩山脉脆弱陡峭斜坡上常见的地貌事件。随之而来的灾难给国家和人民造成了巨大的经济损失，灾难性后果大大减缓了社会和经济持续发展的步伐。虽然滑坡的发生无法预防，但可以通过预防和缓解措施来减少其对生命财产的影响。我们使用地理信息系统和遥感来确定泰国南部的滑坡危险和风险地区，以确保采取适当的措施来预防和/或减轻滑坡的负面影响。结果显示，73%、21%和5%的土地面积分别面临低、中、高度滑坡灾害。面临高度危险的地区位于山区，这表明迫切需要有效的土地利用分区和可持续的农业做法来维持斜坡稳定。进一步的分析显示，553,971公顷，相当于总土地面积的8%，处于高风险之中。讨论了为减少未来山体滑坡风险所需的预防和缓解措施。
Landslides are common geomorphic events on fragile, steep slopes of the granitic mountains in southern Thailand. The ensuing catastrophes have resulted in considerable economic losses to the country as well as to its people, and the disastrous consequences have significantly reduced the pace of sustained social and economic development. Although the occurrence of landslides can not be prevented, it is possible to reduce their effects on lives and property through prevention and mitigation measures. We used GIS and remote sensing to identify landslide hazard and risk areas in southern Thailand to ensure that appropriate measures are used to prevent and/or mitigate the negative impacts of landslides. Results showed that 73, 21 and 5 percent of the total land areas respectively faced low, moderate, and high landslide hazards. Areas facing high hazards lie on mountainous terrain, indicative of the pressing need for effective land use zoning and sustainable agricultural practices to maintain slope stability. Further analysis showed that 553, 971 hectares, equivalent to 8 percent of the total land area, was subject to high risk. The prevention and mitigation measures required to reduce the risks of future landslides are discussed.
