Survey of phytocoenosis and its analysis in Yuelu Mountain Scenic Spot I.Community composition and structure
【摘要】 对麓山景区9个具代表性的植物群落1200 m~2的样地进行了调查,测量并记录其物种种类、株数和胸高断面积等,比较分析其群落组成与结构.结果表明:1)调查群落中共有乔灌木59种,枫香在每个样地中都有出现;白花苦灯笼的数量最多,占物种总数的20.26%;样方4(枫香+飞蛾槭—冬青—杜茎山+木苎麻群落)和样方7(香樟+枫香—白花苦灯笼—稗荩群落)的显著度较大,分别为0.053和0.052;样方9(马尾松—山矾+油茶—苎麻群落)的重要值最大,达318.85;2)9个植物群落的组成与结构存在较大差异,乔木层物种较丰富,层次多样,结构复杂,而灌木层物种相对较少,层次与结构单一.
【Abstract】 Through surveying of 9 representative phytocoenosis in sample aera of 1 200 m~2 in Lu Mountain Scenic Spot, varieties of species,quantities of plants,and surface of trunk section etc.were recorded to analyse its community composition and structurel,results indicated:1 )There are 59 kinds of trees and shrubs,Liquidambarformosana appears in every sample;Tarenna mollissima’quantity is the largest,taking up 20.26% of the total;sample 4 (Liquidambar formosana+ Acer oblengum—llex purpurea—Maesa japonica+ Boehmeria densiflora) and sample 7 (Cinnamomum camphora+ Liquidambar formosana—Tarenna mollissima—Sphaerocaryum malaccense) are more prominent,with index 0.053 and 0.052 respectively;the importance value,318.85,of sample 9’,(Pinus massoniana- Symplocos caudate+ Camellia oleifera- Boehmeria densiflora)is the biggest.2)There are big differences between the 9 phytocoenosis’ composition and structure,tree layer species are more abundant with various level and complex structure,but shrubs species relatively less,with layers and structure single.
