| A Tentative Discussion on the Trend of Ecological Environment Change in Qinghai-Tibet Plateau |
| Qinghai-Tibet Plateau is one of the regions which are most sensitive to environmental changes. This paper has dealt in detail with climate and vegetation changes there, adopted some methods for analyzing meteorological data, and calculated vegetation indices from remote sensing data. The results show that the change of vegetation in this region is not very significant in the past 20 years, but with localized trend of acceleration under the background of global warming, and that temperature, rainfall, evaporation have all tended to rise, which affects plant growing seriously. |
