梅州市芹洋半岛滨水湿地公园植物多样性探讨

2016年3~12月,采用样方调查的方法开展了梅州市芹洋半岛滨水湿地公园植物多样性的调查研究,结果表明：(1)该公园共有维管束植物39科59属66种,除1种蕨类植物(肾蕨)外,种子植物共计38科58属65种,其中,草本植物23种、木本植物42种；从生态适应型看,种子植物中,属于中生性植物占主体(51种),占总种数的77.27％,水生植物和湿生植物分别为6种和9种；(2)从属的分布区类型看,65种种子植物中,属于热带性质的属有43属,占总属数的74.14%；属于温带性质的属有8属,占总属数的16.67%,较好地体现了梅州市热带亚热带过渡的南亚热带植物区系特征；(3)从物种多样性指数(D指数、Hs-w指数、E指数)看,总体上,5区的D指数、Hs-w指数和均匀度E指数相对较高、景观效果最好；6区为3个人工岛,其植物种类、层次感和和分布都低,景观效果最差；其它各区段介于两者之间。

On Plant Diversity Research at Waterfront Wetland Park of Qinyang Peninsulain Meizhou City

In order to study the plant diversity at waterfront wetland park of Qinyang peninsula in Meizhou city,the sample methods were used between March-December in 2016,the results were as follow:(1) The park had the 66 species of the vascular plants belonging 39 families 59 genera, in addition to the 1 species of Pteridophyte(Nephrolepis cordifolia), the seed plants of 65 species belong to 38 families, 58 genera, of which including 23 species of herbs, 42 species of woody plants; of which the 65 seed plants belong to the neutral plants 51 species from the ecological adaptation, and occupied the main body (accounting for 77.27% of the total species), and hydrophyte and aquatic plants were respectively 6 and 9 species;(2)The geography flora of genera of wetland seed plants showed that there were 43 genera belonged to tropical type and the largest proportion(accounting for 74.14% of the total genera), there were 8 genera belong to the temperate type(accounting for 16.67% of the total genera),it showed that Meizhou plants had transitional feature of tropical and subtropical temperature zone;(3) From the species diversity index (D index, Hs-w index, E index), on the whole, the sample-site 5 were the highest area in the comprehensive diversity index and the best landscape effects, and 6 area were the lowest and the worst landscape effects,the other sections were between.
