为了揭示武夷山世界遗产地植被覆盖与其影响因素的空间尺度变化规律，利用武夷山世界遗产地2009年的TM遥感影像及DEM、居民地、道路、河流等数据，运用小波相干分析方法研究该地区两条样带上归一化植被指数（ NDVI）与高程、坡度、坡向、距最近居民点距离、距最近道路距离以及距最近河流距离等环境因子的相关性。研究表明， NDVI与环境因子的关系随尺度变化，在大中尺度上NDVI与海拔、坡度、坡向显著相关，其中海拔是主导控制因子；海拔600 m以下， NDVI与海拔为正相关，而600 m以上， NDVI与海拔的关系在东南季风的迎风坡为正相关，背风坡为负相关，海拔大于1200 m的区域为负相关。

Using wavelet coherency analysis, this paper studies the relationships between normalized difference vegetation index ( NDVI ) and environmental factors at world heritage of Wuyi Mountain. This factors are elevation, slope, aspect, distance to the nearest resident, distance to the nearest road and distance to the nearest river in two transects based on data of TM remote sensing image, DEM, settlements, roads and rivers in 2009.The results show that the relationships between NDVI and envi-ronmental factors change as scale changes.At medium and large scale, NDVI is significantly correla-ted with elevation, aspect, slope.Thus elevation is the dominant controlling factors on the vegetation cover.There is positive correlation between NDVI and elevation below the altitude of 600 m, and a-bove 600 m, the relationships between NDVI and elevation are positive in the windward side of the southeast monsoon and negative in the leeward side, but inversely above 1 200 m.
