中文摘要：
利用2001-2011年间MOD13Q1-NDV I以及TRMM 3B43月降水数据,分析肯尼亚地区11年来植被NDV I与年降水的年际变化趋势及其相关关系.结果表明肯尼亚地区植被NDV I总体上呈轻微下降趋势,且存在着显著的空间差异,3.90%的地区植被NDV I显著增加,15.53%的地区NDV I呈显著减少.肯尼亚地区年降水量总体上呈轻微下降趋势,且存在着显著的空间差异,3.29%的地区年降水量呈显著或低度增加,19.05%的地区年降水量呈显著或低度减少,77.66%的研究区域年降水量基本无变化.肯尼亚地区的植被NDV I与降水有着很好的相关性,93.50%的区域植被NDV I和降水呈正相关,有41.67%的地区呈显著水平以上相关,6.50%的区域植被NDV I和降水呈负相关,仅有0.35%的地区呈显著负相关.
英文摘要：
To evaluate the dynamic changes of inter-annual vegetation and precipitation in Kenya from2001-2011, methods of Sen＇s slope and Mann-Kendall test were employed with MOD13Q1-NDV I and TRMM rainfall series data. The relationship between precipitation and NDV I was discussed and the results show that there had been a little decrease of vegetation cover during the past 11 years and there existed a remarkable difference in spatial distribution. 3.9% of whole regional vegetation significantly increased while 15.53%remarkably decreased. There had been a little decrease of precipitation during the same period and there existed a remarkable difference in spatial distribution. 3.29% of the whole regional rainfall significantly or slightly increased while 19.05% that significantly or slightly decreased. The rest basically undergwent no change（77.66%）.A correlation analysis between NDVI and precipitation shows that the two had a close relationship in this region.In 93.50% of the area, the annual average NDV I was related to the annual precipitation while only 6.50% of the area showed a negative correlation. The annual average NDV I was closely related to the annual precipitation in 41.67% of the area while just 0.35% of the area showed a closely negative correlation.
