东南亚刀耕火种的消失可能会对环境造成毁灭性的后果。橡胶种植园在整个东南亚大陆山区迅速扩大（1-3）。在中国、老挝、泰国、越南、柬埔寨和缅甸的高地上，可能已经有50多万公顷的土地被改造（见图A）。到2050年，用于橡胶和其他多样化耕作系统的土地面积可能增加一倍或两倍以上，主要是通过取代目前被万年青阔叶树和与砍伐相关的次生植被占据的土地。这种将大片土地转化为橡胶的环境后果是什么？
The demise of swidden cultivation in Southeast Asia may have devastating environmental consequences. Rubber plantations are expanding rapidly throughout montane mainland Southeast Asia (1–3). More than 500,000 ha may have been converted already in the uplands of China, Laos, Thailand, Vietnam, Cambodia, and Myanmar (see the figure, panel A). By 2050, the area of land dedicated to rubber and other diversified farming systems could more than double or triple, largely by replacing lands now occupied by evergreen broadleaf trees and swidden-related secondary vegetation (2). What are the environmental consequences of this conversion of vast landscapes to rubber?
