摘　　要：为了更好地保护和管理武夷山自然遗产地的植被景观,利用3S技术和景观指数软件,对其植被景观指数随坡度、坡向和海拔高度空间分异的变化规律进行研究。结果表明:景观面积、景观斑块数量、景观丰度、景观多样性及景观优势度指数的曲线随坡度的增加而呈现先增加后减少的趋势;坡向景观带上6种景观指数从强到弱的顺序为东坡向、东南坡向、西南坡向、西北坡向、西坡向、南坡向、北坡向、东北坡向、无坡向;随着海拔高度的递增,6种景观指数均先增加后减少。建议加强25°<S≤35°、45°<S≤60°景观带、东南坡景观带和海拔1200 m<HB≤1400 m景观带的监测和管理工作。In order to improve protection and management of vegetation landscape in the Wuyishan Natural Heritage,using 3S technology and lanscape indice software,pattern of vegetation landscape indices responding to slope,aspect and altitude mountain factors spatial differentiation in the Wuyishan Natural Heritage was studied.The result showed that,with the slope changing.Indices of landscape path area,patch number,landscape richness,landscape diversity,landscape dominance and landscape fragmentation increased and then decreased;The order of six landscape indices at different aspects was east,southeast,southwest,northwest,west,south,North,Northeast,plain;With altitude increasing,six landscape indices increased and then decreased.Strengthening protection and management of vegetation landscape at 25°S≤35°,45°S≤60°region and 1200 mHB≤1400 m region was recommended.
