The NASA global inventory modeling and mapping studies released one year and a half month maximum synthetic of global dat, based on which the authors analyzed data originated from the Chinese meteorological data sharing service science and data pertaining to northwest air temperature and precipitation, climate, month and year value data sets, etc throughout the period of 1982 to 2013. The Normalized Difference Vegetation Index (NDVI) was analyzed in terms of vegetation spatial analysis, using linear regression analysis, standard deviation, the Hurst index, and the partial correlation analysis methods. The results showed that from 1982 to 2013, the overall NDVI in China, South Asia, and Southeast Asia had an increasing trend. During the 1990s, the vegetation volatility was higher in China, South Asia, and Southeast Asia. Additionally, in the three areas, the NDVI change increased dramatically after 2008, but subsequently decreased in 2010. From 1980 to 2013, the ecological environment of the eastern part of China, the northeast and the south, East Asia, Southeast Asia, India, Thailand, Bangladesh, and the eastern part of Pakistan are generally good. In Western and Northwest China and in other Southeast Asian countries, in South Pakistan, the South and back, the eastern, southern and southwestern parts, the state of the ecological environment are generally poor. From 1998 to 2005, in China, Southeast Asia, and South Asia, the NDVI is reduced. From 2006 to 2013, in China, Southeast Asia, South Asia, the NDVI increased significantly.
