中文摘要	为了查明准噶尔盆地东南缘绿洲-荒漠交错带土壤螨类群落多样性与相似性特征,于2010年4月、7月、9月和11月中旬对该区的自然林、防护林、耕地、菜瓜地、荒草原、灌木林及荒漠等7种不同生境进行采样调查研究。结果表明,共获得土壤螨类5200只,隶属于4目41科61属。在7种不同生境土壤螨类群落多样性间具有明显的差异(p<0.05),Shannon-Wiener多样性指数(H)顺序为灌木林>防护林>自然林>荒草原>耕地>荒漠>菜瓜地,Margalef丰富度指数(M)顺序为自然林>防护林>灌木林>荒草原>耕地>菜瓜地>荒漠。Jaccard群落相似性分析表明,不同生境土壤螨类相似性程度主要为中等不相似(处于0.25~0.50),而在荒漠与自然林、防护林及灌木林之间的相似程度已达到极不相似水平。7种生境土壤螨类聚类和排序分析结果分为林地环境类型、耕作环境类型、荒漠草原环境类型和荒漠环境类型等四大类型。研究结果表明植被类型、土壤湿度和人为干扰是影响土壤螨类群落多样性及其动态变化的主要因素。
英文摘要	In order to understand the diversity and similarity variations of soil mite communities under different habitats in oasis - desert ecotone on southeastern edge of Junggar basin, Xinjiang, an investigation was made on the soil mite communities in natural forest, shelter forest, desert grassland, farmland, shrubbery, vegetable land, and desert in April. July, September and November of 2010. The results are that a total of 5200 soil mites were captured and classified into 4 orders, 41 families, 61 genera. There are a significant differences of the diversity indices among the different habitats (p < 0. 05), the sequences of Shannon - Wiener diversity index (H) are shrubbery > shelter forest > natural forest > desert grassland > farm land > desert > vegetable land. Margalef abundance index (M) are natural forest > shelter forest > shrubbery > desert grassland > farm land > vegetable land > desert. The analysis of Jaccard similarity index indicates that the level of the similarities of the soil mites in the different habitats are moderately dissimilar (0. 25 ~ 0. 50), while the degree of similarity between the desert and natural forest, shelter forest and shrubbery have reached the very dissimilar levels. Using the hierarchical cluster and MDS with SPSS, the seven different habitats can be classified into four groups: Woodland type, cropland type, desert grassland type and desert type. According to the results above we conclude that the diversity and similarity of soil mite communities of the studies sites are obviously different with each other due to the impact of change in the vegetation, soil humidity as well as anthropogenic disturbances.
