Abstract:: Vegetation is more active factor in ecological system, analyzing dynamic change characteristics between it and precipitation and temperature has become research trend in the domestic and foreign research of the ecological environment development. Based on the vegetation normalized index data and meteorological data, the vegetation change trend from 1999 to 2010 was analyzed by using a linear regression method, and at the same time, we analyzed the related degree between NDVI and precipitation, temperature in recent 12 years through the correlation analysis and partial correlation analysis method. The results show that: (1) the vegetation change trend in general is good, vegetation cover change trend is remarkable in south Guangxi and northwest Guangxi, it is not significan in other areas; (2) sparse scrub, dense thickets, evergreen broad-leaved forest and evergreen coniferous forest increased quickly, others was not significant; (3) vegetation response to precipitation is less than temperature, the relevant strength decrease from southwest Guangxi to northeast Guangxi. In conclusion, the response between vegetation cover and precipitation, temperature is related to climate change and terrain profile consistent.
