Abstract

The impact of climate change on Leaf Area Index (LAI) and its spatial pattern was studied by using climate data and LAI data retrieved from AVHRR (Advanced Very High Resolution Radiometer) during the study period (1981-2002). In recent 20 years, most areas of China became warmer and had more precipitation which resulted in higher LAI values and increased Gross Primary Production (GPP). There were higher LAI values in 1990s than 1980s in most areas of China, approximately 75% of the whole China land. In turn, the ecological environment of China had been improved and the region suitable for vegetation growth expanded westward, which leads the increase of the Net Primary Productivity (NPP).
