Abstract

Abstract:The aim of this study was to relate riparian landscape and vegetation patterns to plant species richness. Seventeen stream sites were selected in southern Ireland, and the vegetation within 20m-wide riparian strips was mapped using a global positioning system. Digital maps were created using geographic information systems, and vegetation/habitat classification was carried out at four levels (from broad habitat group to vegetation type). To analyse the structure of the riparian landscapes in the study area, a number of landscape indices were calculated using Patch Analyst software. Plant species richness and community structure were examined using belt transects perpendicular to the watercourse. Riparian zones in the study area are very heterogeneous and exhibit obvious gradients with reference to landscape composition and spatial configuration. This is the result of both natural disturbance caused by streams and human influence. Landscape structure indices were only weakly correlated with plant species richness in the riparian zones investigated, but they did explain most of the variation in the structure and composition of the plant communities.

利用地理信息系统对爱尔兰南部河流沿线的景观和植被模式进行制图和分析

摘要/ Abstract摘要:本研究旨在探讨河流景观和植被格局与植物物种丰富度的关系。在爱尔兰南部选择了17个河流地点，并使用全球定位系统绘制了20米宽的河岸带内的植被。利用地理信息系统制作了数字地图，并进行了4个层次的植被/生境分类(从广泛的生境组到植被类型)。为了分析研究区河岸景观的结构，利用Patch Analyst软件计算了若干景观指数。植物物种丰富度和群落结构采用垂直于河道的带状样带进行测定。研究区河岸带在景观组成和空间配置上具有明显的异质性和梯度。这是河流造成的自然干扰和人为影响的结果。景观结构指数与植物物种丰富度的相关性较弱，但它们确实解释了植物群落结构和组成的大部分变化。

期刊介绍： The journal aims to offer a broad coverage of the subject area, including the following: - biology and ecology of the Irish flora and fauna - microbial ecology - animal, plant and environmental physiology - global change - palaeoecology and palaeoclimatology - population biology; conservation of genetic resources - pollution and environmental quality; ecotoxicology - environmental management - hydrology - land use, agriculture, soils and environment. Submissions on other relevant topics are also welcome, and papers of a cross-disciplinary nature are particularly encouraged.
