Vegetation plays an important role in the climate change,and climate change affects vegetation growth and its photosynthetic activity in return.In this study,we combined datasets of satellite-derived Normalized Difference Vegetation Index(NDVI)from 2001to 2010and climatic factors to analyze spatiotemporal patterns of vegetation growth and its responses to temperature and precipitation over Yimeng Mountainous Area which is the typical region of rocky mountain areas in Northern China.To clarify the trends of the temperature and precipitation,datasets from 1980to 2010are used.Our results show that vegetation growth appeared a trend of improvement in the past decade,and the slope of the Max-NDVI is 0.0026over Yimeng Mountainous Area.In past decade,the significant area of vegetation degradation accounted for 10.52%of the total study area,however,vegetation growth over 28%of study area was well-grown significantly.In the annual scale,the benign development trends of vegetation condition from different seasons were the same as annual trend,especially in the summer and autumn.Datasets from weather stations show that inter-annual variation of vegetation growth has a weak relationship between annual precipitation and mean annual temperature.In monthly scale,although vegetation growth correlated better with temperature than precipitation,the responses in various regions were different to monthly variations of temperature and precipitation.Overall,there are significant variations between the spatiotemporal patterns of Yimeng Mountainous Area and responses to temperature and precipitation.Whats more,this study found that temperature may be the major effective factor which affects vegetation growths in Yimeng Mountain Area.
