对宁德市低海拔茶园进行定点定期调查，共采集到蜘蛛1682头，隶属于21科、39种。其中游猎型蜘蛛是最大的一个类群，有28种，占个体总数的62.49%；结网型蜘蛛是第二大类群，有10种，占个体总数的36.15%。茶园蜘蛛群落多样性、均匀度、丰富度和优势度指数随时间变化而波动，其中多样性和丰富度的波动较大，而均匀度和优势度指数波动较小。宁德低海拔茶园全年都有蜘蛛活动，沟渠豹蛛、草间钻头蛛和机敏漏斗蛛为当地优势种。整个蜘蛛群落及3种蜘蛛优势种种群密度的变化动态与气象因子的变化密切相关。通过灰色关联分析表明，极端低温对整个蜘蛛群落、草间钻头蛛和机敏漏斗蛛种群密度影响最大；极端高温对沟渠豹蛛种群密度影响最大，其次是月日照时数。

Through the investigation on tea field at low altitude in Ningde City, 1 682 individual spiders belonged to 39 species of 21 families were collected and identified. Vagabundae spiders was the largest group, with 28 species and 62.49% of the total individual of spiders, and sedentariae spider was the second largest group, with 10 species and 36.15% of the total individual of spiders. The diversity index, evenness index, richness and dominance index of the spider communities in the tea field fluctuated with time went on. The fluctuations of the diversity index and richness were large, while the evenness index and dominance indices were small. Within the tea field spiders were active in the whole year, in which the three species of spiders, Pardosa laura, Hylyphantes graminicola and Agelena difficilis, were the local dominant species. The occurrence dynamics of the whole spider community and the fluctuation of the three dominant species were closely related to the changes in the climate factors. The results of analyses from the gray theory showed that lowest temperature was the most important factor in influencing the population density of the whole spider community, the species of Hylyphantes graminicola and Agelena difficilis; highest temperature was the most important factors in influencing the population densities of Pardosa laura, and the next was the sunshine hours.
