Abstract

Abstract: In order to analyze the temporal and spatial pattern of vegetation coverage change and its correlation with climatic factors in Shandong province in recent ten years, this paper utilized MODIS/NDVI data, precipitation data and temperature data from 2005 to 2015, combined the model of center of gravity to realize the spatial pattern analysis of vegetation changes in Shandong province in last decade. Kriging was used to interpolate the precipitation and temperature data, then, the correlation coefficient analysis of the influence of precipitation and temperature on the vegetation cover during 2005 to 2015 was carried out. Finally, we analyzed the lagging response of vegetation to precipitation and temperature. The results show that there is a significant increase in vegetation coverage in Shandong province in recent ten years, precipitation and temperature have different degrees of positive correlation with vegetation growth, and the impact of temperature on vegetation is greater than the impact of precipitation on vegetation. Vegetation growth on the precipitation and temperature response showed significant lag effect.

Key words: Shandong province, vegetation coverage, climatic factor, correlation analysis, dynamic monitoring
