摘要
利用内蒙古鄂温克旗草甸草原地区1981-1990年的气象资料和植被调查资料,分析了气候变化对草甸草原植物群落特征和主要优势植物的影响。结果表明,研究区域内近10a的气候具有逐渐变暖的趋势,降水增多有利于提高植物多样性,同时,主要优势植物对降水的敏感性要强于气候温度的变化。本研究将为探讨草甸草原生物多样性和生态系统功能对气候变暖的响应与适应,以及为预测草甸草原在全球气候变化下的发展趋势提供借鉴和依据。
Based on the 1981--1990 investigation data about the climate and vegetation of meadow grassland in Inner Mongolia Ewenki Banner, the study analyzed the effect of climate change on community properties and dominant species in meadow grassland. The results showed that the temperature increased from 1981 to 1990. More precipitation could increase species diversity, and precipitation was better than the temperature for several kinds of dominant species. The research would provide the basis for the response of biodi versity and ecosystem function to temperature increase, and it would be better to predicting the variation of meadow grassland under the climate change.
