【摘要】 水生植物是营造园林水体景观的一种重要植物材料。随着人们对其景观与生态功能重要性认识的不断加深,水生植物在园林水体中得到广泛的应用。本文针对近几年来长沙城区中水景建设的快速发展,对城市水体中水生植物的园林应用现状进行了历时两年多的实地跟踪调查,并在此基础上对长沙城区中的水生植物造景、建植与养护管理等情况进行了较为系统的研究,希望为丰富水生植物景观的物种多样性和景观多样性,以及为水生植物的进一步推广应用提供良好的借鉴。主要研究结果如下:1.通过最新的系统实地调查得出:长沙城市水体中已有应用的水生植物共72种,分别隶属于30科,其中挺水植物54种,浮叶植物9种,浮水植物3种,沉水植物6种。大面积应用的水生植物仍为常见种,部分引进的园艺种已逐步推广应用。2.调查发现在城市水体中有更多的野生水生植物得到重视和应用,但仍缺少分析长沙城市水体主要水生植物物候谱;与以往调查不同的是:调查中研究了主要水生植物的适宜水深范围,为水生植物的合理配置和应用提供更全面依据。3.调查发现近年来水生植物在长沙城市水体造景中的应用逐渐增多。水生植物的大量应用,绿化和美化城市水体,并表现良好的景观价值和生态效益,是长沙城市水体内园林植物景观的重要组成部分。4.在对长沙市城市水体园林植物景观典型植物配置模式调查的基础上,总结性的提出了长沙水体园林植物景观现有典型植物配置模式,通过较详尽的植物造景与季相分析,发现其水生植物造景各有特色。5.根据水体特点、造景要求。在充分调查研究的基础上,创新性的运用层次分析法(AHP法)构造长沙园林植物景观评价模型,并通过对长沙市城市水体园林植物及配置模式进行分析,推荐适宜长沙城市水体园林绿化用植物及典型水体植物配置模式。更多还原

【Abstract】 Aquatic plants are essential materials for waterscape. Being deep understanding of their importance for landscaping and ecological function, aquatic plants are used more and more widely. For hot construction of waters cape in Chang Sha Scenic Area recently, this paper made a systematic study on its conditions of planting design ,planting style ,maintenance and management of aquatic plants ,which was based on a field investigation for more than two years. Furthermore, this paper did hope to provide useful experiences to how to improve landscaping diversity and species of aquatic plants and how to enlarge their further uses .The results were summarized as follows :1. According to the latest system investigated ,totally 72 species of aquatic plants were surveyed ,which are belonged to 30 families in Chang Sha Scenic Area. These plants consisted of 54 species of Emergent plants, 9 Floating-leaved plants, 3 Floating plants and 6 Submerged plants. The widely used aquatic plants are common species, and some cultural varieties are also extensively applied. More and more wild aquatic plants were introduced to the area of the Chang sha. However, there are still la ck of evergreen species for aquatic plants.2.There are more wild hydrophytes in the city waterscape get the value and applications, but the analysis of the phenospectrum of dominant species of aquatic plants in Chang Sha Scenic Area is still short. Different from the old investigated style the proper depth range of some aquatic plants were also investigated. These results are beneficial to planting design and utilization of aquaticplants.3. Investigate to discover more and more the hydrophyte are applied in chang sha city water body in recent years/The application green and beautify the city water body, and bring the good view value and the ecosystem performances, is the importance part of city.4. Analyzing the aquatic plants and their configure mode in typical waterscape of Chang Sha Scenic Area, different kinds of landscape meanings were indicated.5. According to the water characteristics and landscape demands and long-term investigation, Analyzing the aquatic plants and their configure mode in typical waterscape of Chang Sha Scenic Area by AHP method,that’s a innovation.recommend the aquatic plants and their configure mode which is suit for Chang Sha.更多还原
