荒漠群落

研究结果表明：灌木荒漠群落中，优势种群或共优种群的重要值远远大于亚优势种群，在维持群落结构和功能方面占据十分重要的地位。

The results indicated that in the desert shrub communities , the dominant species or co-dominant species presented a much higher importance value than subdominant species did thereby playing a very important role in maintaining the structures and functions of the communities .

荒漠植物群落有经向、纬向和海拔高度变化的分布格局，水分是影响植被径向分布的主要因素，气候则反映了植被纬向和海拔高度分布的变化。

Water is the major actor to influence the longitudinal distribution and climate mainly influence the latitudinal and altitudinal distribution .

荒漠植物群落过渡地带一般具有较高的物种多样性和较低的生态优势度。

The transition zone of desert plant communities generally has high level of species diversity and relatively low degree of ecological dominance .

由此可以确定，降雨和气温影响了荒漠植物群落结构的季节变化，而对年际变化影响不大；在气候条件变化较小的范围内，荒漠植物群落结构保持相对稳定。

Therefore it could be determined that the rainfall and temperature have greater impact on the seasonal variation of desert plant community structure , but have little impact on inter-annual variations .

In addition , in this paper , the pattern-process-scale of rodent communities in different disturbances was analyzed , and then the characteristic of ecological process of rodent communities was definite under different disturbances in during the course of desert ecosystem fragmented .

通过对新疆准噶尔盆地沙质荒漠鼠类群落结构的两次对比分析，力求探讨其群落变化趋势，结果表明鼠类群落结构是动态变化的，优势种的更替是普遍存在的。

This paper tries to find the change tendency of rodent population through comparative analysis of the structure of desert rodent population in Dzungaria basin . The result shows the structure of the rodent population is dynamic and the substitute of dominant species is common .

优势度最低，仅0.084。荒漠鸟类群落与固沙林鸟类群落的相似性最高，0.52。

While the dominance was the lowest , only 0.084.The similarity between desert bird community and fixing sand forest bird community was the highest , up to 0.52.Community diversity increased with number of species increasing , but decreased along with the increasing of the dominant species percentages .

3）荒漠植物群落结构层次中，灌木层占居主导地位，群落灌木层物种多样性水平（0.769~1.451）远远大于草本层（0.193~0.254），且草本层物种多样性受灌木层影响较大。

3 ) The structure of desert plant community is dominated by the bush layer . The species diversity indices of bush layer ( 0.769-1.451 ) is much higher than that of herb layer ( 0.193-0.254 ), and the diversity in herb layer is strongly influenced by bush layer .
