Land use change has been affecting the function and structure of landscape ecological system directly or indirectly,and it influences the landscape processing in the surface of the earth. This paper uses 3S technology in macroscopic. Combined the integrated technology of ecological quantity analytical method with GIS technology through ArcGIS and Fragstats, and the author study the images of 1972,1991,2001 and 2005 and obtained land use data in Jinghe County. Then, the change of land use/cover and landscape pattern had been analyzed in this paper in Jinghe County of Xinjiang, The conclusions are as follows: (1)The trend of LUCC is that the area of oasis expends slowly in nearly 33 years between 1972 to 2005 in Jinghe County. While the area of human oasis expends fast, the area of natural oasis decreases. It is the area of farmland and human forestland increasing while the grassland decreasing in class.(2)The area of water area is mainly influenced by Ebinur lake, so the area expends a little in this period. (3)The area of salinization land expands at first and reduces later. Its area is largest in 1990 and decrease largely in 2005. The area of sand land decreases and the other land class increases while the probability of transfer is always high. The period in the middle is higher than others two-periods.(4)Landscape change is also obviously in the decades. Totally, landscape density increases, the largest path index decreases at first and expends later, the weight area index decreases and the shape of landscape becomes regulation. The nearest distances, the degrees of reunite and outspread decreases. It shows that the connection of mainly path in 1972 is better than 2005, the patch becomes more complexity. From the change of Shannon′s Diversity Index and Shannon′s Evenness Index, we know that the diversity of landscape and the Interspersion Juxtaposition Index increase. The degree of diversity landscape and fragmentation increasing also shows that the land uses become more complex. The reason of the change is that human activity influenced the path, the substance, energy and information stream changes, so the landscape pattern changes, the index of fragmentation and diversity increases too. At the inner of oasis, the patch complexity influenced by the level of agriculture, the CONTAG increases either. At the edge of oasis, the area of farmland expends, so the shape of landscape becomes complexity and the scrambling increases. All in all, it is essential to intensify the spatial relationships among landscape elements and to maintain the continuity of landscape ecological process and pattern in the course of area expansion.
