Abstract: Through the investigation on tea field at low altitude in Ningde City, 1β682 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.
