延安市城区斑块化湿地秋季主要昆虫种间联结分析
|
摘要
为探究延河区域秋季揺蚊大量孳生的原因,基于2×2列联表,运用方差比率法、χ2检验,联结系数(AC)、点相关系数(PCC)、成对物种间的匹配系数(PC、DI、OI)等方法,分析了延安市城区斑块化湿地秋季主要昆虫种间联结。结果表明:秋季主要昆虫群落总体关联性为显著负联结(VR=0.552 <1),χ2检验结果无极显著种对,3对为显著相关,整体呈现出独立和随机分布格局。210个种对中,|AC|> 0.6的种对有87个,|PCC|≥0.3的种对有61个,PC≥0.3的种对有27个,DI≥0.3的种对有72个,OI≥0.3的种对有75个。其中与揺蚊相关的89个种对中,χ2检验结果仅有2对为显著联结,AC与PCC指数都显示物种间联结度较弱,PC、DI、OI指数多集中于区间0≤PC <0.3,表明揺蚊与同期生存的其他物种间无显著或较强的种间联结关系。
This paper researched the cause for multiplication of Chironomidae in Yan'he watershed by analysis of the interspecific association between the major insect species in patchiness wetlands of Yan'an based on the use of 2×2 contingency table,a series of parameters including variance ratio analysis,χ2-test,association coefficient(AC),Person's correlation(PCC),and matching coefficient between pairs of species.The result showed that the variance ratio analysis of major insect species in autumn was significantly negatively correlated(VR=0.552<1),χ2-test results showed no extremly significant correlation,3 pairs were significantly correlated,interspecific association tended to independent and random distribution overall.In the 210 species pair,there were 87 species pairs with |AC|>0.6,61 species with |PCC|≥0.3,27 species with PC≥0.3,72 species with DI≥0.3,and 75 species with OI≥0.3.There was significantly interspecific association for 2 species pairs,among 89 species pairs which were related to Chironomidae,AC index and PCC index showed that the interconnection between species was weak,PC,and DI and OI indexes were concentrated in district(0≤PC< 0.3).The result showed that there was no significant or strong interspecific associations observed between Chironomidae and other species in same period.
