From 2002 to 2003, once every 1-2 weeks, a systematic survey was carried out on the 25-year-old organic tea gardens, pollution-free tea gardens with poor vegetation, and common tea gardens in the 25-year-old organic tea gardens in the Magu Mountains in southern Anhui. There were 6224 individuals of common tea garden spiders, belonging to 14 species of 8 families; 7430 individuals of pollution-free tea garden spiders, belonging to 16 species of 8 families; 8005 individuals of organic tea garden spiders, belonging to 29 species of 12 families. In the three types of tea gardens, the number of species and individuals of spiders was more from March to May and October to November, and the number of species and individuals was less in July and December. The common tea garden in this study has less vegetation. The tea garden management is slightly extensive. Chemical pesticides are indiscriminately applied. And the number of spider species and individuals is the least. Although the vegetation around the pollution-free tea garden is less, the management is meticulous. According to the control indicators, the number of spider species and individuals is more than that of ordinary tea gardens. Organic tea garden plants are relatively prosperous without pesticides, and the number of spider species and individuals is the largest.The tea garden environment and management measures have a great influence on the composition of the spider community.
