摘　　要：为了合理保护和利用天敌及科学地选取抽样方法,2015年和2016年合肥地区乌牛早茶园茶蚜、假眼小绿叶蝉、卵形短须螨和双斑长跗萤叶甲与其天敌之间的空间关系,并比较两年间同一种天敌与该害虫空间跟随关系密切程度差异的原因。运用地学统计学方法求得天敌和害虫各自的变程,用灰色关联度方法分析害虫与天敌变程之间的关联度,关联度值越大的天敌在空间上对害虫的跟随关系越密切。与害虫空间跟随关系密切的前三位天敌,2015年茶蚜的是茶色新圆蛛、锥腹肖蛸和粽管巢蛛,2016年是锥腹肖蛸、八斑球腹蛛和鳞纹肖蛸,两年只有锥腹肖蛸相同。2015年假眼小绿叶蝉的是茶色新圆蛛,八斑球腹蛛和粽管巢蛛,2016年的是八斑球腹蛛、茶色新圆蛛和鳞纹肖蛸,两年间前三位天敌中有八斑球腹蛛和茶色新圆蛛相同,但位次不同。2015年卵形短须螨空间跟随关系密切的前三位天敌是茶色新圆蛛、粽管巢蛛和鳞纹肖蛸,2016年的是鳞纹肖蛸、粽管巢蛛和八斑球腹蛛,两年间前三位天敌中有粽管巢蛛和鳞纹肖蛸相同,但位次不同。2015年双斑长跗萤叶甲的是八斑球腹蛛、粽管巢蛛和鳞纹肖蛸,2016年的是鳞纹肖蛸、粽管巢蛛和茶色新圆蛛,两年间前三位天敌中有鳞纹肖蛸和粽管巢蛛相同,但位次不同。初步分析表明年度间与害虫跟随关系天敌位次的变化原因是,害虫个体数与某种天敌个体数之比,比值越小,天敌与害虫跟随关系越密切,似乎是天敌食饵资源短缺所致。To protect and use of natural enemies and provide scientific sampling methods, in this study, the spatial relationships among the natural enemies of the insect pests Toxoptera aurantii Boyer, Empoasca vitis Gothe, Breuipalpus oboyats, and Monolepta hieroglyphica were investigated in the tea garden of ＂WuNiuZao＂ in the Hefei suburban district, China in 2015 and 2016. The reasons for differences in the relationship between the same natural enemies and the pest species in the two years were evaluated. The ranges of spatial dependence （RSDs） of natural enemies were calculated using a geostatistics method, and the spatial relationships among enemies and pests were analyzed using grey relational analysis. A greater relative degree indicates a closer following space about the relationship between natural enemies and pests. The relational grade analysis showed that the three main enemies Neoscona theisi, Tetragnatha maxillosa and Clubiona japonicola Boes. et Str had a close relationshipwith Toxoptera aurantii in spatial-following relationships in the ＂WuNiuZao＂ tea garden in 2015. Although the three main enemies Tetragnatha maxillosa, Theridion octomaculatum Boes.et Str., and Tetragnatha maxillosa remained the same during the two years, the sorting was different in 2016. The relational grade analysis showed that the three main enemies Neoscona theisi, Theridion octomaculatum Boes. et Str., and Clubiona japonicola Boes. et Str had close relationship with Empoasca vitis in spatial-following relationships in the ＂WuNiuZao＂ tea garden in 2015. The three main enemies included Theridion octomaculatum Boes. et Str, Neoscona theisi, and Tetragnatha syusmata in 2016. Theridion octomaculatum Boes. et Str. and Neoscona theisi remained the same during the two years, but the seating arrangement was different. The relational grade analysis showed that the three main enemies Neoscona theisi, Clubiona japonicola Boes. et Str, and Tetragnatha syusmata had consanguineous relations with Breuipalpus oboyats in spatial-follow
