In order to probe into the spatiotemporal effect of shrub canopy on the distribution of soil faunal community diversity, a field investigation on ground-active arthropod by the pitfall trapping method was undertaken between Caragana Shrub microhabitats under different microsite conditions in desertified region in spring, summer and autumn. The relative interaction intensity (RⅡ) was used to examine the ‘arthropod island’ acted by shrub canopy under two microsite conditions with/without sand cover across seasonal changes. It was found that:(1) the Sorenson index between two microsite conditions increased across seasonal changes; Tenebrionidae was the dominant group which was not affected by the microsite conditions and seasonality; along with microsite condition and seasonal changes, the similar and/or reversing distribution of ‘arthropod island’ acted by shrub canopy was found in the ground-active arthropods; (2) it was found that there was significantly (p < 0.05) greater RⅡ value regarding Carabidae in the microsite without sand cover relative to that with sand cover only in summer season; whereas the RⅡ values regarding Tenebrionidae and Formicidae were found to follow a reverse pattern between microsite conditions across seasonal changes; (3) it was found that the RⅡ value regarding total abundance was significantlygreater in the microsite without sand cover relative to that with sand cover only in summer (p < 0.05), whereas it was followed a reverse pattern between the spring and autumn seasons; it was found that the RⅡ values regarding group richness in each microsite conditions were regulated by the seasonal changes; however, the RⅡ values regarding group richness were found to be little affected by the microsite conditions and seasonal changes. It was conclude that the ‘arthropod island’ regarding arthropod abundances was remarkably affected by the microsite conditions and seasonality. The ‘arthropod island’ regarding group richness was much affected by the seasonality and little by microsite conditions. It was suggested that the shrub canopy facilitated the ground-active diversity irrespective of both microsite conditions and seasonality in desertified region.
