Abstract:

The spatial distribution of different soil types and landuse types were analyzed by using geographical information system, landscape ecology analysis methods with ArcGIS and Fragstats typical in red soil region in the Zhuxi watershed. The major findings of this study include: 1) red soil is the main soil type in the watershed of Zhuxi River, the other types of soil has the less area, and their distribution is scattered. 2) The west region of the watershed is human landscape, such as farmland, residential centre, industrial and mineral land, traffic land. While the east region is mainly occupied by forest land. The area of the unused land is small. The whole watershed presents the scene of “west farm and east forest”. 3) The patch density of soil landscape is small, edge density’s amplitude is large, and patch shape is complex. 4) With the increasing of human disturbances, the patch density of landuse landscape has the tendency of increasing, edge density is gradually decrease from farmland, garden, forest land, grassland, residential and industrial land, traffic land, water to unused land, edge shape tends to regular, and patch shape is complicated and various.
