中文摘要	以19942000年内蒙古阿拉善锡林高勒地区荒漠灌木的定位观测资料为基础，利用灰色关联分析方法，分6个时段分析了5种荒漠灌木种群密度与日平均气温、日平均最高气温、日平均最低气温、降水量和020cm、2080cm地温6个水热气候因子的关联性。结果表明，白刺与上年旺盛生长季降水量，霸王与上年生长季降水量有较大关联性，其它3个灌木种则与当年生长季降水量的关联性最大。当年全年日平均气温、日平均最低气温与刺叶柄棘豆和红砂，当年全年020cm地温、日平均最低气温与短脚锦鸡儿，当年全年日平均最低气温和当年生长季020cm地温与霸王，以及当年生长季日平均气温和020cm地温与白刺的种群密度具有较高的关联度。多数荒漠灌木种群密度与降水量的关联性大于热量因子（霸王除外），但由于生长、发育低温阈值偏高，日平均最低气温可能是荒漠灌木种群波动的基础性气候因子。此外，霸王作为荒漠灌木的优势种，对荒漠高温、少雨的干旱气候有着极强的适应性，这些研究结果对深人开展荒漠灌木种群生态与气候关系研究具有一定参考意义。
英文摘要	Based on the data of locating observation on desert shrub from 1994 to 2000 in Xilingaole area of Alashan League in Inner Mongolia, the relevance of population densities of five desert shrub species to six water-thermal factors, including average air temperature, average maximum air temperature, average minimum air temperature, precipitation and ground temperature of 0 - 20cm and 20 - 80cm, was analyzed by using the gray relevant analysis on six time intervals, such as annual period, growth period, flourishing growth period, last annual period, last growth period and last flourishing growth period. The results showed that ： 1 ）. The relevance of the precipitation during the last flourishing growth period to Nitraria sibirica and the relevance of the precipitation during the last growth period to Zygophyllura pterocarpura were more significant, while the relevance of the precipitation during the growth period of the same year to other three species was more significant. 2）. There existed the following highly significant relevancies： the annual daily average air temperature and annual daily average minimum air temperature of the same year to Reaumures soongorica and Oxytropis aciphylla; the annual average ground temperature（0 -20cm）and annual daily minimum air temperature of the same year to Caragana brachpoda; the daily average minimum air temperature and the average ground temperature （0 - 20cm） during the growth period of the same year to Zygophyllura pterocarpura; and the daily average air temperature during the growth period and the average ground temperature（0 -20cm）of the same year to Nitraria sibirica. 3）. Except for Zygophyllura pterocarpura, the relevance of precipitation to desert shrubs was higher than thermal factors. But daily average minimum air temperature might be a basic climate factor for the fluctuation of desert shrub population, as the desert shrub had a higher minimum temperature threshold for the growth. As one of dominant species of desert shrub, Zygophyllura pterocarpura had a strong adaptability to the arid climate with high temperature and rare precipitation.
