三明市区城市绿道藤本植物资源调查与分析

Investigation and Analysis of Lianas Resources in Urban Greenway of Sanming City

[目的]调查与分析三明市区城市绿道藤本植物。[方法]采用样线调查方法,沿该绿道20 km主线及山间小道,对线路两侧5 m范围内的藤本植物进行调查。[结果]三明市区城市绿道藤本植物有30科59属83种,含有蕨类植物、裸子植物、被子植物,其中被子植物有28科57属81种,且以双子叶植物为主,有25科53属77种,占总种数的92.8%;单子叶植物处于次要地位,有3科4属4种,占总种数的14.5%。此外,该绿道的藤本植物以木质藤本为主,草质藤本次之,种类超过10种的只有1个科,所含藤本植物种数占总种数的20.3%,含6~10种的科也只有1个,含2~5种藤本植物的小型科有19个科,单种有9个。该绿道未见含藤本植物6种以上的属,含2~5种的属有16个,所含藤本植物种数占总种数的48.2%,单种属比例最高,有43个属,所含种数占总种数的51.8%。且在83种藤本植物总种数中,野生的有61种、栽植的有22种,分别占藤本植物总种数的73.5%、26.5%。[结论]该绿道藤本植物多样性相对集中在少种科(属)、单种(属)中,且该绿道两旁的原有野生藤本植物资源比较丰富,植物多样性高。

[Objective]The aim was to investigate and analyze the lianas in urban greenway of Sanming city.[Method]The lianas within 5 meters on both sides of the 20 kilometers main line of the greenway and the mountain path were investigated by line transversal survey method.[Result]The results showed that there were 83 species of lianas in 30 families,59 genera,including gymnosperms,fern,and angrosperms.Among angiosperms,there were 81 species,57 genera,28 families,and dicotyledonous plants were the main species,77 species,53 genera,25 families,accounting for 92.8%of the total species.Monocotyledonous plants(3 families,4 genera,4 species)played a secondary role,accounting for 14.5%of the total species.In addition,the lianas in this greenway were mainly woody lianas,followed by grass lianas.There was only one family with more than 10 lianas,which accounted for 20.3%of the total number of lianas.There was only one family with 6-10 lianas,19 small families with 2-5 lianas,and 9 single lianas.No genera containing more than 6 species of lianas were found in this greenway,and there were 16 genera containing 2-5 species,the number of lianas accounted for 48.2%of the total number of lianas,and the proportion of single species was the highest,with 43 genera,the number of lianas accounted for 51.8%of the total number of lianas,among which 61 were wild 22 species were planted,accounting for 73.5%and 26.5%of the total species of lianas,respectively.[Conclusion]The diversity of lianas in this greenway was relatively concentrated in a single species(genus)of few species(genera),and the original wild lianas on both sides of this greenway were rich in resources and had high plant diversity.
