摘要
针对我国北方河岸带的特点,提出了从地貌结构、植被群落、景观三个方面的13个因子组成的河岸带自然度综合评价指标体系,包括:河岸弯曲度、河岸断面几何形态、河岸带宽度、河岸林群落物种多样性、均匀度、郁闭度、顶级适应值、乡土树种比例、建群种胸径级、实生幼株丰富度、群落形态指标、群落色彩指标、动物指标;并根据近自然程度,将河岸带划分为自然、较自然、半自然、人工四种类型。
Based on the characteristic of north China, comprehensive evaluation index system for riparian naturalness offers 13 indicators from topographical structure, vegetation community and landscape aspect, including ; riparian curve degree, the profile shape of riparian, width of riparian, species diversity, evenness index, canopy densities, climax adaption value, native species proportion, diameter class of dominant species, richness i＇ndex of seeding-growth, community shape index, community color index,animal index. According to the nature closeness degree, riparian is divided into 4 classes;nature, relative nature, half nature, artificial.
