| Landscape pattern research the core of landscape ecology. Especially the study of the dynamic change of the drainage basin's landscape pattern can open out the evolutional rules of large-scale ecological progress. The newest theory of landscape ecology about the landscape pattern, scale, grade popularization, and the rising of TUPU theory of geography information give new chances to the study of the dynamic change of large-scale landscape pattern. Regarding the landscape pattern as a core, this dissertation attempts to build a research framework which amalgamates landscape ecology theory and geography information TUPU theory.This dissertation analyzes the developing background of landscape ecology and geography information TUPU from different respects, such as geography, landscape ecology, cartology, RS, and GIS technology. According to the developing status of geography, landscape ecology and cartology, the article bring forward that there are 4 respects about the underway work of landscape pattern study, i.e., regional geography unit and its grading system, the relations between landscape pattern and ecological progress, the expressing means of landscape pattern, the dynamic TUPU analysis of landscape pattern. It is the research key of landscape pattern to resolve the summarization of landscape pattern, the classification of landscape pattern as well as the information and expression of landscape pattern. The scale level of landscape study has a grading frame. The landscape organization structure being ordinal, the geography arrangement of the landscape unit can be incarnated on different levels of scales. Thus, different special patterns, i.e. landscape pattern, are formed. However, this scale-structure system is the expressing mode of geography TUPU. In order to realize the TUPU expression of landscape pattern, the size of the minimum unit should firstly be confirmed through which the TUPU may express landscape.The dynamic change of landscape pattern could be expressed through the dynamic analysis of landscape information TUPU. We may made use of pattern– scale– grade– TUPU - time system to show the qualitative change status of landscape change, i.e. landscape evolution. Only during special periods, it is significative to consider the landscape dynamic. If we want to obtain correct large-scale dynamic changing information of landscape pattern, we must depend on modern remote sensing technology. Therefore, the remote sensing technology plays an important role in the TUPU analysis of the dynamic change of landscape pattern.Through the practice of Xinkai River drainage basin, the analysis and expression of pattern-scale-grade-TUPU-time system are attempted. This dissertation made use of the bran-new means of landscape analysis (landscape information TUPU) which played a very unique role in dynamic analysis of large-scale landscape pattern. This new means can not only simulate the dynamic progress of landscape pattern but also open up the ecological evolutional rules of landscape pattern, forecast its trend as well as offer important scientific basis for the continuable developing plan and decision of the ecology in this drainage basin.This dissertation synthesized a series of ground usage and wetland landscape TUPU on the foundation of the thirty-three years'(1969~2001) ground usage and the 4 peroids of special data about wetland landscape (1969, 1979, 1992, 2001 ) in Xinkai River drainage basin. This article made an TUPU analysis of the change of land-use pattern and wetland landscape in the Xinkai River basin, which has been made with the support of ARC/INFO software after the Markov model of space probability and the model of landscape pattern index. The result shows that the land-use pattern in the basin has been unreasonable, as is proved by such facts as existence of few woods, serious land saline, desertification and progressive reduction of grassland—a general degradation of the eco-environment in the area.The wetlands of Xinkai River Basin had changed to meadow, farmland, sandy land or salina to different degrees with the increase of population, intensification of land-use practices and changes of hydrological conditions, leading to the converse growth of the vegetation. Moreover, the total acreage of wetland went through up-and-down course from violent reduction to remarkable increase. The fragmentized situation in wetland landscape of this basin is serious. In 2001, the average area of the maximum parcel decreased by 71.02%, 71.08% and 64.76% respectively, compared with that of 1969 and the SL increased from 0.78 to 0.93.This research achievement can provide scientific basis for the protection and rational utilization of wetlands in the Basin.
