| 摘 要： | 对奇台沙拐枣(Calligonum klementzii)自然植物群落特征进行了调查分析,依据自然植物群落特征对异地重建模式进行了探讨。结果表明:(1)自然群落特征数量指标中,优势度、重要值、多度、频度、高度、生活型、生长型是决定重建群落特征的主要参考指标。(2)奇台沙拐枣重建植物群落理论最小种植面积为2286-2857m2;主要物种数为10种,其中小乔木2种,灌木3种,草本5种;重建群落优势种奇台沙拐枣、梭梭(Haloxylon mmodendron)、羽状三芒草(Aristida pennata)最小物种保存数分别为96-120株、40-80株、120-240株;种群年龄结构按自然群落模式配置。

| Abstract: | According to the investigation of the natural community of Calligonum klementzii,the characteristics of natural community and reconstruction pattern were studied.These results showed that:firstly,dominance importance value,abundance,frequency,height,life form and configuration of growth form of the natural communities are the main reference indexes of the reconstruction community.Secondly,theoretical minimum planting area of reconstruction communities of Calligonum klementzii is 2286-2857m2.Main species are... |
