摘要:
通过分层随机取样对杭州西溪国家湿地公园的草本 层自生植物展开调研,分析其物种组成与多样性特征,并探 讨群落组分及其影响因素。结果表明:1)共调研到自生植物 260种,农用地生境多样性指数最高,草地生境最低;2)群 落组分的生境间差异主要反映在乔木小苗、藤本和入侵植物的 重要值上;3)块石驳岸和自然驳岸的物种丰富度分别与坡向 和水位相关;4)人工植被的高度和盖度对群落各组分产生了 不同影响;5)群落分类得到的45个群落组在不同位置形成了 丰富多样的景观。研究结果在未来面向低维护、地域性的自生 植物景观应用中具有重要的参考价值。

Abstract:
In this study, the stratified random sampling method was used to investigate the spontaneous vegetation (SV) of herb layer in Hangzhou Xixi National Wetland Park. Species composition and diversity characteristics were analyzed, and the influencing factors to the community composition were discussed. The results showed that: 1) 260 species were investigated, the highest value of diversity index was in farm land, while the lowest was in grassland; 2) The differences of community composition between habitats were mainly reflected in arbor seedlings, vines and invasive plants; 3) Species richness of stone revetment and natural revetment was respectively affected by orientation and water level; 4) Height and coverage of artificial vegetation had different effects on each part of community composition; 5) SV communities were classified into 45 groups, which produced a rich variety of landscape aesthetics.These results will provide a reference in future applicationof SV to lowmaintenance regional landscape.
Key words:  landscape plant  spontaneous vegetation  diversity  community composition  community classification
