| 摘 要： | 以阜康绿洲-荒漠交错带的荒漠植被为研究对象,利用样区内植被常规调查资料,改进了法国生态学家M.Godron从工业生产中发现并引入生态学研究中的稳定性测定方法,并将研究方法推广到植被群落的空间稳定性研究。根据这种方法,累积种类百分数与累积相对盖度比值越趋近于20/80群落就越稳定,在20/80这一点上是群落的稳定点。研究结果证实:从空间上看,绿洲-荒漠交错带不同植物群落稳定性不同;绿洲-荒漠交错带的荒漠植被群落稳定性受种间竞争、环境压力和干扰活动三个因素的影响,即使建群种相同的群落稳定性也会出现较大差异。 |

| Abstract: | The deserts vegetation at Fukang oasis-desert ecotone is studied in this paper.Based on the vegetation survey data for the sampling field, the method of stability measurement,which was discovered and applied to the ecology study in the industry manufacture by French ecologist M.Godron,is modified and introduced to study the spatial stability of community of vegetation.The result shows that the community is more stable when the percentage accumulation and accumulated relative cover degree trend to 20/80,which is the stability ratio of community.The result verified that the stability of different plant community is different in different deserts vegetation of oasis-desert ecotone from the space.The community stability of deserts vegetation of plant at Fukang oasis-desert ecotone is influeced by interspecific competition,environment pressure and disturbances,even the community stability with the same edificators appear bigger difference. |
| Keywords: | Fukang oasis-desert ecotone deserts vegetation cover degree community stability |
