| Abstract: |
| Under the background of the global warming, as one of the Chinese serious soil erosion and climate change sensitive regions, the contiguous areas of Shaanxi Gansu Ningxia have received universal attention. In order to reflect the major tendency of the climate change in those areas, specially the improvement of the climate status since 1999, analysis is made of the temperature and precipitation record between 1951 and 2004 in 39 observatory stations by utilizing the linear regression method and tendency analysis method. The results show that: the warming drying trend is obvious, and the areas has been under the dry status for many years, and the temperature becomes higher in fluctuation gradually, while the precipitation becomes smaller. This bad climate condition has been seriously affected the ecological environment building of the contiguous areas of Shaanxi Gansu Ningxia. Only after 1999, under the background of warming drying trend, the temperature becomes lower, while the precipitation becomes bigger, which is a good climate change tendency and has the vital significance regarding climate reforming and the rebuilding of ecological environment. |
