摘要

南昌市湿地维管植物多样性

专 业：生物工程 学 号：5602207069 学生姓名：魏泰维 指导教师：陈少风

摘要

本次研究通过实地调查、采集标本及查阅相关文献，对南昌市区几个典型湖泊及南昌市内赣江部分区段湿地维管植物进行了调查统计。调查结果表明该地共有维管植物144种分属44科，物种多样性较为丰富，这与该地处于亚热带及人为影响有关。以上湿地植物生活型以地面芽植物和一年生植物占优势，以被子植物为主。其中含有较多的科是禾本科和菊科，含有较多种的属是蓼属和莎草属，出现频率较高的物种主要有狗芽根、空心莲子草、白茅等。调查到的植物有不少巳广泛应用于湿地园林景观和人工湿地，某些种类具有一定的应用潜力。此次研究沿湿地水分梯度按照水边、沙滩、远水草地、林草交错带顺序对南昌市内的部分湿地维管植物进行了调查统计。调查区域为：南昌大学前湖校区（非种植园林植物）、前湖、赣江生米大桥到八一大桥段（渔舟湾湿地公园）、青山湖。调查结果显示维管植物的生活型组成中，多年生或一年生杂草及多年生禾草组成远水草地群落的主体，植物的生活型以地面芽和地下芽植物为主。本研究旨在使我们能够使我们大致了解南昌市湿地维管植物多样性结构、复杂程度、组织水平和生境差异。

Abstract

Nanchang wetland vascular plant diversity

Abstract

In This study,I investigated wetland vascular plants through field survey to collect data,access to relevant literature on several typical lakes and part of the section gan river in Nanchang,. In particular the lakes in Nanchang like Qian lake, Xiang lake, Qing shang lake and so on. Survey results show that in a total of 144 species of vaccular plants belonging to 44 families, species diversity is more abundant, this is the place in the subtropical and human impact on. Over the life form of wetland plants and annuals hemicryptophyte dominated by angiosperms based. Which contains more families are Gramineae and compositae, with more variety of the genus is genera Polygonum and sedges, the higher the frequency of the main species of Cynodon dactylon (L.) Pers.alligator grass, imperata and so on. Investigation into the plant have been widely used in many wetland landscape, some species have some potential applications.In the study I carry out a survey on study along the gradient from the surface water ecotone, beach, far plants, the grass within the transitional zone , tree belt in Nanchang part of the order of wetland vascular plants.The survey area are: the Qian lake area of Nanchang University(no-cultivated garden plants), the Qian lake ,the Qian lakek, the Bayi brige to Shenmi bridge of the Gan River(Yuzhouwan Park), Qinqshan lake. In each section of plant life form community functional group composition, the pernninal weeds and perennial grasses and the most of the grasses are community composition, life form to the ground and under ground shoots plant-based bud. The means that we can make to our understanding of vascular plants in Nanchang diversity of wetland structural complexity, the level of organization, stability and habitat differences, but also help to promote local research Ann and regional biodiversity conservation process.
