Spatial-temporal Evolvement Characteristics of Climate Productivity for the Plants on Inner Mongolia Desert Steppe
Thornthwaite Memorial model and other statistic methods were used to calculate the climate-productivity of plants with the meteorological data from 1961 to 2007 at 9 stations distributed on Inner Mongolia desert steppe. The spatial and temporal variation characteristics of climate-productivity were analyzed by using the methods of the tendency rate of the climate trend, accumulative anomaly, spatial difference and so on. The results showed that the climate-productivity kept linear increased trend over Inner Mongolia desert steppe in recent 47 years, but not significant. In spatial distribution, the climate-productivity reduced with the increased latitude. The climate-productivity in southwest part of Inner Mongolia desert steppe was growing while it in the southeast was reduce. The variation rate of the climate-productivity increased from the northwest part to the southeast part of Inner Mongolia desert steppe. In recent 47 years,the decrease extent of the climate-productivity in southeast Jurh was the greatest, and the region was the sensitivearea of the climate-productivity variation.
