摘　　要：【目的】为了正确认识克拉玛依植物群落的结构和功能,为克拉玛依地区植被的经营管理、植被恢复和生物多样性保护提供依据。【方法】通过野外采样,应用χ2检验、Ochiai关联指数、种间联结系数AC对克拉玛依11个典型植物群落进行了种间联结分析,【结果】克拉玛依11个典型植物种间呈显著或极显著的种对约占了全部种对的近4/5,极显著、显著负联结对数均多于正联结对数;猪毛菜和其他典型种的关联性最高,无叶假木贼和其他典型种的关联性最低。【结论】各植物种群生长相对比较集中,存在一定的斑块现象,各个群落稳定性较差,集群分布;群落趋向于独立分布。群落内各植物间对水分等资源的竞争较为激烈,群落未达到演替的顶级群落。【objective】The purpose of the paper was to understand the structure and function of vegetation community in Karamay,and to offer advices for vegetation management,rehabilitation and diversity protection.【Method】Based on the data collected from the samples in the field,The inter-specific relationships of the main species in Karamay were studied by using χ^2-test,Ochiai association index and AC association index.【Result】The result indicated that nearly four fifth inter-spectific groups of the eleven typical vegetation species showed significant or extreme significant correlation,which is more than the number of positive correlation species groups.The highest correlation appeared in the inter-specific groups between Salsola L.and other species,while the lowest appeared between Anadasis.aphylla and other species.【Conclusion】The population of all species grew relatively concentrated with a few blank spaces.The populations were not so stable and tended to distribute independently.Within population,the different plants had serious competition on water.It had not yet reached the climax population.
