摘      要：This article analyzes the correlation of NDVI and two meteorological data including temperature and precipitation,and probes the spetial pattern of responding sensitivity of the vegetation to temperature and precipitation *** constructing the NDVIrindex,the relation between vegetation cover and land use in the Longitudinal Range-Gorge Region（LRGR）is *** conclusion is as follows:（1） The time lag effect that vegetation responds to temperature and precipitation change is ***- ferent regions have different delay time corresponding to maximum correlation *** to response time of precipitation and temperature combination,three kinds of temperature-precipi- tation forms are defined,namely,precipitation and temperature in the same time,precipitation prior to temperature and temperature prior to precipitation.（2）The spatial distribution of sensitivity,of which vegetation responses to temperature,is characterized by several high and low scattered correlation *** from temperature,two insensitive regions and two sensitive belts are formed to pre- sent the response of vegetation to precipitation.（3）The NDVIris constructed,which can perfectly re- flect the corresponding relationship between meteorological factors and land use condition in the LRGR.
