- Abstract:
- The exploration of the relationship between the vegetation coverage and climate change plays an significant role on the reconstruction of vegetation and restoration of ecological environment to study the dynamic of the vegetation in specific areas and its influence on climate. NASA/GIMMS half synthetic normalized difference vegetation index (NDVI) from 1982—2005 and meteorological data was used to study the characteristic of the NDVI’s annual change and it’s response to the climate factors about different types of vegetation in different regions of the Tianshan Mountains. The results show that: (1) All vegetation index of the Tianshan Mountains increased in the fluctuations of the past 25 years, and it was consistent with the overall trend. The trend was conducive to the improvement of ecological environment. (2) The main vegetation in different regions was also different, which had a great impact upon the mixed vegetation index. (3) Different types of vegetation had different response to the climate, but they were all positively correlated with the temperature and precipitation .So it indicated that temperature and precipitation were two important natural factors to affect the vegetation index. (4) The vegetation index in plain increases quickly than it did in the mountains . It indicated that the growth of vegetation was influenced not only by natural factors， but also by human factors.
