| 摘 要： | 以朱溪流域为例，将地理信息系统、景观生态学分析方法相结合，运用ArcGIS以及Fragstats软件，探讨红壤地区不同土壤类型的空间分布，以及土地利用方式的空间分布。结果表明：1)酸性岩侵蚀红壤是朱溪流域的主要土壤类型，其他类型的土壤拥有的面积相对较少，而且分布得比较零散。2)流域西部多是耕地、居民点及工矿用地、交通用地等人文景观；而东部多为林地；未利用地面积小；整个流域呈现“西农东林”的景象。3)朱溪流域土壤景观的斑块密度小，边界密度变幅大，且斑块形状复杂。4)随着人类干扰的增加，流域内土地利用景观的斑块密度有增加的趋势，边界密度从耕地到园地、林地、草地、居民点及工矿用地、交通用地、水域、未利用地逐渐减小，边界形状亦趋于规则，且土地利用景观形状复杂多样。

| 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 was the main soil type in the watershed of Zhuxi River,the other types of soil had the less area,and their distribution was scattered.（2） The west region of the watershed was 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 was small.The whole watershed presentsed the scene of ＂ west farm and east forest ＂ .（3） The patch density of soil landscape is small,edge density ＇ s amplitude was large,and patch shape is complex.（4） With the increasing of human disturbances,the patch density of landuse landscape had the tendency of increasing,edge density was 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 was complicated and various. |
