| 摘 要： | 分析了内蒙古高原小针茅草原植物群落地上净生产量、生长季节地上平均生产量的生期变化与降水量和气温的相互关系，结果表明：小针茅草原地区最近10年气温明显升高，降水量的波动呈随机性。小针茅草原植物群落初级生产力与4－8月降水量有显著的直线回归关系，而与年平均气温、≥5℃的年积温没有明显相关关系。

| Abstract: | The relationship between the long-term dynamic of aboveground net annual primary production , aboveground average growth season production and precipitation, and air temperature was analyzed in Stipa klemenzii plant community in NeiMongol Plateau. The result showed that the annual air temperature rose in the recent ten years, and the precipitation fluctuation was stochastic. There was a significantly linear correlation between aboveground primary production and the accumulated rainfall from April to August, and there was no correlation between production and air temperature in the Stipa klemenzii plant community. |
