摘    要:于2010年8月下旬,采用同样方法调查了香溪河长江入口处到峡口镇段海拔145~185m库岸带植物分布情况。结果表明:调查范围内植物有29科、59属、64种,其中禾本科(9属11种)和菊科(8属9种)20种,这两科物种数最多;主要优势物种为荩草、狗牙根、狗尾草(重要值分别为0.9237、0.5614、0.4283),这三种植物可作为库岸消落带生态恢复的物种;物种丰富度和多样性随海拔升高呈增加趋势,生态优势度呈减小趋势。较大可能的原因是受到淹水时间长短的影响。

Abstract:This article investigates theplantdistributionalong the riversidefromthe entrance of Xiangxi River to the Yangtze RivertoXiakou Town atthe altitude of 145 -- 185m byusing sampling method in late August, 2010. The results show thatthe plants belong to 29 families,59 genera,64 species. The maximum number of species areGramineae and Compositae~ the dominant species are Arthraxon hispidus, Cynodon dactylon and Setaria viridis(the important values are 0. 9237,0. 5614,0. 4283) ,which can be used as the ecological restora- tion speciesatthebank of riparianzone. The species richness and diversity increase graduallywith the increase of altitudewhile the ecological dominance tends todecrease,whichis likelycaused by the duration of flooding.
Keywords:Xiangxi River plant distribution investigate
