摘要

根据2000-2009年MODIS数据及相应地区的气象数据

对古尔班通古特沙漠南缘近10a的植被指数(NDVI)与气象因子之间的关系进行了分析。结果表明

研究区近10a年均温、降水量和NDVI总体呈上升趋势;NDVI的月变化呈弱双峰型

最大峰值出现在5月

次峰值出现在8月

最小值在2月;变标度极差分析结果表明

研究区未来全年和各季平均气温、降水及NDVI将继续上升

NDVI与同期的气温、降水的变化趋势相吻合。

Abstract

Relationship between normalized difference vegetation index(NDVI) and climate factors were analyzed in the south of Gurbantunggut Desert using the NASA/MODIS data(from 2000 to 2009) and meteorological data in Fukang City.The results showed that the annual average temperature

precipitation and NDVI has increased in the past 10 years.The monthly variation of NDVI showed a slight double-peak pattern

with the first maximum in May

the second maximum in August and the minimum in February.The rescaled range analysis of NDVI showed that yearly and seasonal temperature

precipitation NDVI will increase continuously in the future

and NDVI change will coincide with the change in temperature and precipitation.
