英文摘要	Due to the heterogeneity of land surface features in a large-scale region, this study examines the effectiveness of a multiple models strategy in soil moisture retrieval from MODIS in Xinjiang, and established a robust model for soil moisture retrieval from remote sensing data in arid and semi-arid areas where diverse land surface covers such as bare soil, sparsely vegetated and densely-vegetated lands exist. Specifically, the composed inversion models: ATI-based, TVDI-based and an averaged model were developed and used to estimate land surface soil water content in bare-soil, densely-vegetated and sparsely-vegetated areas, respectively. The models were verified and validated using the in-situ measured data, and the result indicates that, the proposed composite model performed better and achieved more accurate estimate of Xinjiang surface soil moisture than either ATI-based model or TVDI model.; http://gateway.webofknowledge.com/gateway/Gateway.cgi?GWVersion=2&SrcApp=PARTNER_APP&SrcAuth=LinksAMR&KeyUT=WOS:000310770800102&DestLinkType=FullRecord&DestApp=ALL_WOS&UsrCustomerID=8e1609b174ce4e31116a60747a720701 ; Computer Science, Artificial Intelligence; Computer Science, Theory & Methods; CPCI-S(ISTP); 3
