摘　　要：县城滨河地带是展示地域特色景观的重要地段。从景观设计角度,实地踏勘与资料分析相结合、定性与定量分析相结合,运用归纳方法、聚类分析法、特尔菲测定法等方法,对广西县城滨河场地进行了自然类型划分:按河床宽度(27个县城为大尺度型滨河场地,22个为中尺度型,22个为小尺度型,4个为小尺度以下型);按横断面(59个"U"型,16个"V"型);按地貌组合(8个小平原、石山、高丘复合型,9个岩溶平原、峰丛复合型,等);按沙洲与岛屿分布(31个沙洲与岛屿型,44个无沙洲与岛屿型);按河岸植物(滨河湿地型场地和无乔木、原生乔木、次生护岸林滨河场地)。分类成果可作为"因地制宜"进行滨河景观规划设计的基础要素。The riverfront of county towns is an important site which shows the geographical features of land-scape.From the perspective of landscape design, riverfront sites of county towns in Guangxi are identified in terms of natural types.Based on field survey, data analysis, the combination of qualitative and quantitative a-nalysis, the natural factors are studied and sorted by the methods as induction , clustering methodology, and Delphi Mensuration.According to the width of riverbed, in our classification there are large-scale riverfronts in 27 towns, middle-scale riverfronts in 22 towns, small-scale ones in 22 towns, and 4 riverfronts under small-scale.According to transverse section, there are 59 riverfronts in the shape of “U” and 16 ones shaped in“V”.According to landform assemblage, 8 towns are complex of small-plains, tors and hills, and 9 towns con-tain features of karst plains and peak clusters.According to distribution of sandbank or island, sandbanks or islands are separate in 31 county towns while 44 towns without them.According to vegetation along the river, the riverfronts are wetland types, no vegetative cover, but natural arbor trees and secondary woods retaining the bank.The research may provide reference for future riverfront landscape design in adjusting to local environ-ment.
