According to inquisitional result based on remote sensing technology, this paper narrates the regulations of Yutian oasis land cover dynamic change. Considering macroscopic research, 4 main land cover types are chosen, which are desert, oasis, ecotone and water body and they represent distinct characteristics of the local place. On the basis of field survey and statistical data, the paper uses PCI software to preprocess these data and the 2 satellite images (see Fig. 1). To improve overall post-classification precision, this study uses spatial structure information of satellite images to reclassify the result by using fuzzy optimum clustering firstly and gains a rather high classification precision which guarantees the need of analysis fully. Through analyzing these images resulting from post-classification comparation, the paper sums up the concrete quantificational dynamic distributed data of 4 main land types covering a span of 9 years and regulation of the local ecological environmental system. It finally points out that the trend of Yutian regional oasis desertification expansion are related to two important reasons, i.e., impact of natural environment and impact of human activities. In order to improve the local ecological environment, people in Yutian county should take measures suitable to local conditions to protect oases environment through shelterbelt construction, development of socio-economy and sustainable development.
Key words： land cover; dynamic change; spatial structure information
