Abstract: Drought is one of the most damaging natural disasters, which might cause huge losses to agricultural production and the local economy. Using the Vegetation Condition Index (VCI) calculated by the remote sensing data of AVHRR and MODIS as monitoring indicators to study the temporal and spatial variation in Jiangsu Province was the first step. Then, we discuss its relationship with the four climate factors about precipitation, air temperature, relative humidity and sunshine duration according to the measured meteorological data about Jiangsu Province from 1982 to 2010. Not only could quantitatively describe the space changes in vegetation drought, it could also reflect positive or negative effect by long-term climate. The results showed that the average VCI value for nearly 30 years in Jiangsu was on a rising curve, and the overall regional drought had eased. Referring to the four climate factors, the annual average temperature rose, the annual average precipitation was essentially unchanged, while relative humidity and sunshine duration decreased. Also, temperature and relative humidity had a remarkable correlation with VCI, which were the main factors affecting the drought.

Key words: vegetation condition index, drought changes, climate factors, correlation analysis
