中文摘要：

以朱溪河流域为例,将地理信息系统、景观生态学和数量分析方法相结合,运用ArcGIS以及Fragstats软件,探讨红壤地区不同土壤类型下土地利用方式的多样性。结果表明：①受人类活动干扰较小的土地利用类型,如林地、园地、草地、水域及未利用地主要分布在酸性岩侵蚀红壤、酸性岩红壤、泥沙土以及黄泥沙田地区;而与人类活动密切相关的土地利用类型,如耕地、居民点及工矿用地、交通用地,在流域内的各种土壤类型中都普遍分布,表现出强烈的广泛性。②土地利用类型的多样性指数很大程度上受到人为因素的干扰,而土壤类型的多样性指数则与土地利用类型的分布息息相关。③土壤类型与土地利用类型的平均斑块面积与多样性指数具有很好的相关性,随着平均斑块面积的增加,流域的多样性指数呈上升的趋势。

英文摘要：

Combined the Geographical Information System（GIS）,the landscape ecology and quantitative analysis methods with the software of ArcGIS and Fragstats,it is analyzed the diversity of land use types for different soil types in the small watershed of Zhuxi River.The major findings of this study include： ① the land use types with less disturbance by human activities,such as woodland,garden land,grassland,waters and unexploited land are mainly distributed in the areas of acidite eroded red soil,acidite red soil,sediment soil and yellow sediment soil;while the land use types affected strongly by human activities,such as farmland,settlement and industrial and mineral land,traffic land,are existed on all kinds of soil type in the river,showing the intense universality;② the land use diversity index are strongly influenced by human activities,while the soil type diversity index is closely linked with the distribution of land use types;③ average patch area and diversity index has the high relativity with each other under the soil and land use types.The diversity index of river watershed appeared the increasing trend with the increase of the average patch area class area.
