WANG Ling et al(Department of Geography,Normal College,Shihezi University,Shihezi,Xinjiang 832003)  
This study aimed to make land use map of Shihezi City with the support of GIS and the land use status map of Shihezi as basic components and on the basis of this select various landscape index and make quantitative analysis on the characteristics of Shihezi desert oasis landscape pattern from the landscape diversity,landscape architecture index and other characteristics of the three plaques.The results showed that: the main plaque types in Shihezi Reclamation landscape were arable land and water areas,which totally account for 58% of the region;farmland,gardens,woodland and urban sites such as mining landscape were embedded in this oasis landscape in the form of mosaics,and their fractal index was high due to the strong impact of human activities;arable land and mining land distribution was scattered,but marshes and other uncultivated land were distributed relatively concentrated.The advantage degree of the landscape was low because there was no advantageous type in this landscape and all patches distributed equably which was easily to be disturbed so that the whole landscape was unstable.Comprehensively speaking,the landscape in Shihezi region was rather complicate,and its diversity index,fragmentation degree and heterogeneity was high.
