2)  wetland community
湿地群落
3)  mono-species wetland
单种群落湿地
1.
The results indicated that purification efficiency of COD_ cr by mono-species wetland was almost the same as that by poly-species wetland; the removal rate of T_ P by poly-species wetland was higher than that by mono-species wetland, while the removal rate of T_ N by the former was lower than that by the latter.
结果表明,两种湿地对有机物CODcr的净化效果差异不明显,但多种群落湿地对TP的净化效果优于单种群落湿地,而单种群落湿地对TN的净化效果又强于多种群落湿地。

湿地松介绍 湿地松 (Pinus elliottii Engelm.) 科属:
松科

别名:
国外松

形态特征:
常绿大乔木。原产美国东南部,高30~36m,胸径90cm。针叶3和2针一束并存,深绿较粗硬。球果通常是2-4个聚生,少有单生,种鳞平直或稍有反曲,鳞盾肥厚有光泽。树皮灰褐色,纵裂成大鳞片状剥落。

分布与习性:
该树适应性较强,喜光,适应性广。在我国山东平邑以南直至海南岛的陵水县、东自台湾、西至成都的广大地区内多处试栽均表现良好。性喜夏雨冬旱的亚热带气候,对气温的适应性强。

繁殖与栽培:
用播种繁殖。球果一般在霜降前成熟,摘取球果,日晒,去翅,低温干藏。每斤种子1.2-1.4万粒。春季条播,每亩6-7斤,产苗3-4万株。一年生苗高可达30公分以上,当年即可上山造林。在园林中行独植或丛植时,可用3-5年生大苗,带土团定植。

应用:
湿地松苍劲而速生,适应性强,材质好,松脂产量高。中国已驯化成功达数十年,故在长江以南的园林和自然风景区中作为重要树种应用,是很有发展前途的。
木材可供建筑、纸浆、坑木、枕木、水工和胶合板等用。松脂产量高,质量好。
