| 英文简介 | Studies on the faunistic taxonomy,biodiversity and tempo-spatial variation of soil mites is a central topic for discussion in the study of the soil zoology.The soil mites as an important functional components of the soil animals with high species richness,wide distribution,and abundance in microarthropods in soil.They play a vital role such as decomposition of soil organic matters, changing of physico-chemical properties of the soil, cycling of nutrients and energy,ecotoxicological diagnosis of the soil,and monitoring soil environment variations in the ecosystem. In order to provide scientific evidence of the present status ,characteristics of the faunal distribution ,species diversity and tempo-spatial variation of the soil mites of which in relation to the environmental factors in the Mountain-Oasis-Desert ecosystem in the southwest of Junggar basin in Xinjiang, northwest of China,the studies on the faunal distribution,the seasonal dynamics,the interrelationships between the faunal distribution and seasonal dynamics and as well as the soil environmental factors will be conducted by the combined methods of the morphological taxonomy and ecological methods ,using the main parameters such as the elements of fauna,individual number and density,Shannon-Wiener species diversity index, Margalef abundance index ,Pielou evenness index ,Jaccard similarity index ,Sorensen similarity inedx,density-group index.The Euclidean distance(ED) and hierarchical cluster (multidimensional scaling,MDS) analysis,Oribatid mites MGP analysis,maturity index (MI) of the predatory mites,as well as the assemblages of soil mites will be analysed with respect to the site and soil environmental variables in the different habitats using principal component analysis(PCA), canonical correspondence analysis(CCA), multivariate similarity cluster analysis(MSCA)and redundancy analysis(RDA).The seasonal dynamics between the soil mites' faunal ditribution patterns and the main environmental stressors(factors) by the animal community distribution coefficient(ADC) and multivariate similarity cluster(NMDS) in the different habitats and as well as in the different seasons in the ecosystems. In the end ,the comprehensive analysis will be made on the spatio-temporal variability of the soil mites' faunal distribution patterns in that area, and thier response to the environmental factors.The project has an important theoretical significance and scientific value in the comprehensive understanding of the whole China's soil mites fauna,biodiversity,systematic evolution,and the ecological effects of the soil mites ,as well as the bioindicators to the soil quality in our country. |
