Land Use Change Pattern of Analysis Based on Landscape Ecology in Nanhai District of Foshan City

摘要

Land use is an important field in the global environment change. This paper, taking Luocun town of NanHai District ofFoshan city as an example, with the help of GIS technology, mathematics model and landscape-ecology theory, analysesthe landscape pattern's changes of land-use from different region scales and different levels(the whole luocun Town andevery village in luocun Town). The study shows that the fragmentation level increased. The edge degree and the PD areincreased, and the landscape contagion indexes increased, but the LPI decreased. It suggests that the fragment degree andthe separate degree are increased constantly. The landscape evenness index is increased, which suggests that the area ofland-use patch class approach to equality. The change of the landscape pattern takes on district diversity, in the mainly,which can be cured up two different area (the eastern area and the western area). The villages in the east have a highland-use index all the time, and they have a low extent during 1987-2002; but the villages in the west have a high extentduring1987-2002, the landscape diversity index and landscape evenness index are increased, the land-use develop to thediversity and at the same time, the land-use develop to the evenness, also.
