Abstract：.The city garden is an important part of the city ecosystem. As spider is the main natural enemies of city garden pests, it plays an important role to control pests for agri-forestry ecological system, it also has a strong environmental indication. Protection and utilization of city garden spider resources is an important content of comprehensive prevention and control of garden pests. Jiangxi province, is located in the south bank of middle and lower reaches of Yangtze River in southeast of China, and it has a typical subtropical continental monsoon climate. The province, whose ecological environment is good within the forefront of the country, is subdivided into a total of 11 city districts that include Nanchang, Fuzhou, Jiujiang, Ganzhou, and so on. This investigation including the garden cities and their suburb involved in (A) the Ganzhou city and its suburb, (B) the Ji'an city and its suburb, (C) the Fuzhou city and its suburb, (D)the Nanchang city and its suburb, (E) the Shangrao city and its suburb, (F)the Jingdezhen city and its suburb, (G) the Xinyu city and its suburb,(H) the Jiujiang city and its suburb,and (I) the Yichun city and its suburb. After identification, it had been found that there were 322 known species belonging to 30 families and 132 genera, of which, 19 new record species in Jiangxi and 44 undefined species. Analysis of community structure showed that the size order of spider family number were C>F=I>B>D>A=E=G>H, spider genera number were C>I>F=H>A=B=D=E=G, spider species number were C>H>I>D>G>F>B>E>A, spider individual number were C>H>I>D>G>F>B>E>A. Diversity analysis showed that, the size order of Marglef richness index M were H>A>G=I>D>B>E>C>F, Berger-Parker dominance index d were D>A>F>E>H>B>I>G>C, Smipson diversity index D were F>A>D=E>B>I>G>H>C, Mackintosh evenness index E were C>A=B=D=E=F>G>I>H. Cluster analysis showed that the spider community similarity between different city gardens of Jiangxi, followed by C=G-F-I-E-B-A=D-H, their exchange decreases gradually.In a word, the spider resources of city gardens in Jiangxi was rich, and the spider families, genera, species number were at a high level. The spider diversity formation of city gardens in Jiangxi were closely related to the recent urbanization expansion areas increasing, artificial garden facilities more complete, transplanting a large number precious trees to these cities from their surrounding mountains in garden construction, and frequent human disturbance and other factors. In short, there were many spider types in the city gardens of Jiangxi, in which common species for agroforestry and residential district predominate, with few endemic species.
