浑善达克沙地苔藓物种多样性

调查了浑善达克沙地10类植被地面生苔藓植物物种多样性及分布。结果表明：（1）该区共发现苔藓植物23科54属115种，其中苔类6科7属9种，藓类17科47属106种（包括变种）；具有4种生长型，其中茎叶体苔类4种，叶状体苔类5种，顶蒴藓类63种，侧蒴藓类43种；优势科有丛藓科（Pottiaceae）、真藓科（Bryaceae）、柳叶藓科（Amblystegiaceae）、青藓科（Brachytheciaceae）等；优势属有真藓属（Bryum）、青藓属（Brachythecium）、细湿藓属（Campylium）等；该区苔藓植物可分为10个区系地理成分，以北温带成分为主；白桦（Betula platyphylla）林、湿地、沙地云杉（Picea mongolica）林、爬地柏（Sabina vulgaris）灌丛等生境下苔藓植物多，且随着水分增加物种数量和生长型类型增加，优势种个体亦增大；（2）Shannon-Wiener多样性指数与Patrick丰富度指数变化趋势基本一致，而Simpson优势度指数变化相反，土壤水分和空气湿度是苔藓植物物种多样性和丰富度的主要影响因子；（3）除了沙地云杉林与臭柏灌丛和白桦林外，物种相似系数总体较低。     

杭州西溪湿地苔藓植物种类与群落调查

在野外调查、采集和标本检视基础上,记录杭州市西溪湿地苔藓植物33科48属58种1亚种1变种。其中,树生赤藓(Syntrichia laevipila)为浙江省分布新记录。该湿地苔藓植物种类丰富度及特有性较低,含5种的科只有齿萼苔科(Lophocoleaceae)和丛藓科(Pottiaceae),占总科数的6.1%;仅1种的科共18科,如缩叶藓科(Ptychomitriaceae)、牛毛藓科(Ditrichaceae)、珠藓科(Bartramiaceae)、木灵藓科(Orthotrichaceae)、疣冠苔科(Aytoniaceae)等,占总科数的54.5%。在苔藓群落中,土生苔藓群落占优势,而且土生苔藓群落的物种多样性也最丰富,其他依次为石生群落、木生群落、水生群落。生活型统计显示,交织型与丛集型占绝对优势,合计53种,占总种数的83.33%;漂浮型和悬垂型都只有2种,分别占总种数1.67%,基本不代表该区苔藓植物生活型特征。     

安徽升金湖自然保护区湿地草本种子植物区系研究

对安徽升金湖湿地自然保护区的湿地草本植物区系进行了初步分析,研究表明,该区共有湿地草本种子植物59科173属275种,以禾本科（Gramineae）、菊科（Compositae）、莎草科（Cyperaceae）等为优势科,而以菱科（Trapaeeae）、三白草科（Saururaceae）、茨藻科（Najadaceae）等为该植物区系的表征科;以蓼属（Polygonum）、苔草属（Carex）、蒿属（Artemisia）等为优势属,但属的组成较为分散,寡种属和单种属占总属数的97．69％,表明该区植物成分较为复杂,物种多样性指数较高。从分布区类型看,科以热带成分占明显优势（30．52％）;属泛热带分布属最多（21．39％）,北温带分布成分次之（13．87％）,总体上温带成分（38．73％）略多于热带性成分（34．10％）。表明该植物区系地理成分复杂,过渡性明显,分布区类型多样,具有热带、亚热带与暖温带的多重性质,但以亚热带性质为主。     

广东博罗县小金河植物区系研究

本区计有野生维管束植物１７２科、５３２属、９７８种（包括变种、变型）。发现２新种，１新变种和３个广东新记录种。本区系的表征科为山茶科、壳斗科、桑科、芸香科、紫金牛科、樟科等，这些科大都是热带－亚热带分布式的，代表了本区系的性质。在属的地理成分中，本区以热带成分１７３属（占总数的３５．２％）和热带－亚热带成分１６９属（占总数的３４．４％）为主，说明了本区系具有由亚热带向热带过渡的南亚热带特征。本区与     

科尔沁沙地松树山地区苔藓植物物种多样性与分布特征分析

通过标本采集和群落调查,探明科尔沁沙地松树山地区有苔藓植物76种(包括变种和亚种),可归为苔类(9种)和藓类(67种)两个大的类群,隶属于21科、41属;可划分为7种区系地理成分,以北温带成分、世界广布种和东亚成分为主要区系成分, 分别有48种、12种和8种。石缝土层、岩面、树干小生境苔藓植物群落丰富,少数物种局限分布在一种小生境中,多数物种同时分布在两种以上小生境中。维管植物群落共有地面生苔藓植物39种,优势种有双色真藓(Bryum dichotomum)、土生对齿藓(Didymodon vinealis)、小疣冠苔(Mannia triandra)、西伯利亚疣冠苔(Mannia sibirica)、褶叶青藓(Brachythecium salebrosum)。随着水分条件改善,地面苔藓植物群落优势种构成发生有规律地变化,顶蒴藓类→顶蒴藓类+叶状体苔类→叶状体苔类+顶蒴藓类→侧蒴藓类+叶状体苔类+顶蒴藓类。认识群落随水分条件变化的特征对从更大尺度上认识苔藓植物结皮层形成和维持有重要参考价值。     

长白山哈泥泥炭地7种苔藓分布与环境关系研究

在长白山哈泥泥炭地调查7种苔藓的典型生境,共计93个样方,计测样方中苔藓植物的盖度和包括泥炭全氮（TN）、全磷（TP）、K^＋和Ca^2＋等在内的9个环境因子,应用典范对应分析对数据进行处理,做出样方、物种与环境因子关系二维排序图,排序图直观地反映苔藓植物与环境因子间的关系。结果表明,排序图中同种苔藓为主的样方多数集中分布,个别分散分布;水位埋深、沼泽水pH以及乔木郁闭度和灌木盖度是影响泥炭地苔藓植物生态位分异的主要环境因子,泥炭全磷（TP）对苔藓植物分布影响较大。7种苔藓中,尖叶泥炭藓（Sphagnum capilifolium）、大泥炭藓（S．palustre）在乔木郁闭度和pH梯度上,喙叶泥炭藓（S．fallax）、沼泽皱缩藓（Aulacomnium palustre）在水位埋深和灌木盖度梯度上,生态位分异明显。锈色泥炭藓（S．fuscum）、桧叶金发藓（Polytrichum juniperinum）和中位泥炭藓（S．magellanicum）在各个环境梯度上生态位都比较相似。     

上海地区湿地水生维管束植物及其区系特征

在参照相关资料基础上，结合实地调查，得出上海地区湿地水生维管束植物共49科107属179种。从植物生态型和生活型等方面来划分，上海地区水生维管束植物可主要分为内陆河湖水生植物、河口海岸滩涂植物和湿生植物3种类型。从区系组成来看，包含5种以上的12个较大科构成了上海地区水生维管束植物的主体，其中禾本科和莎草科种类最多；区内各属种数都在10种以下，包含3种以上的属有19属，共79种，分别占总属数的17．8％和总种数的44．2％。从区系分布区类型来看，水生蕨类植物种主要有4种分布区类型，世界分布为主要类型；而水生种子植物属有13种分布区类型，其中6个热带分布类型共有39属，占总属数的61．9％，6个温带分布类型共有24属，占总属数的38．1％，表明上海地区水生种子植物区系具有偏热带性质。同时，讨论了水生维管束植物在湿地生态系统以及湿地生态恢复中的重要作用。     

河南省湿地植被特征种植物区系研究

根据有关调查资料,对河南省湿地植被特征种的区系组成、科属种三级分布区类型及其与植被的关系等进行了分析,阐述了河南省湿地植被的特征。结果显示,维管植物有50科99属249种,种子植物科的分布区类型有6个,属有10个,种有13个。科属都为世界分布类型最多,除此类型之外,泛热带和北温带成分占有突出的位置。种分布区类型中,世界分布显著减少,而以东亚分布为最多,热带亚洲分布次之,北温带分布居第三;中国特有分布中,中国亚热带分布为最多。从浅水湿地到草丛湿地植被,其建群种虽都以世界分布科为最多,但热带分布数量减少,而温带分布数量逐渐增多。河南省湿地植物区系与东亚和热带亚洲以及北温带的植物区系联系最为紧密,而在中国南北方湿地植被的区系关系中较接近于南方亚热带的湿地植被区系特征。     

浙江磐安蕨类植物地理成分及区系相似性分析方法的研究

分析了浙江磐安蕨类植物区系的组成和分布区类型,现知磐安共有蕨类植物34科、60属、112种(包括各种变种和变型)。磐安蕨类植物以东亚分布类型为主,特别是中国-日本分布类型最多,亚热带、暖温带特征显著,该区应置于中国-日本森林植物亚区从暖温带向亚热带过渡的范围内。最后,文章生成了反映22个蕨类植物区系相似性关系的二维投影图和最小生成树图,对区系间的相似性关系进行了研究。结果显示,两种方法相结合能较客观地反映蕨类植物区系间的异同,可为多区系比较提供参考。
