河南宝天曼化香林特征及物种多样性

根据10块样地的野外调查材料,对河南宝天曼化香林的土壤性质、植物区系成分、群落外貌、群落结构以及物种多样性特征进行了初步分析。结果表明:(1)化香林土壤较贫瘠,区系组成较丰富,其属的分布类型以温带性质的属最多,热带性质的属也占一定比例;(2)化香林的生活型以高位芽为主,叶级谱中以中型叶为主;(3)化香林的垂直结构可分为乔木层、灌木层、草本层,亦有少量的层间植物;(4)化香林的优势种显著,群落物种的丰富度、多样性、均匀度指数的总趋势为灌木层>草本层>乔木层,但在海拔梯度上的分布并未表现出明显的规律性。     

黄河下游河滨湿地不同草本植物群落物种多样性研究

暖温带河滨湿地植被以草本植物群落为主。以黄河下游河滨湿地的河漫滩和背河洼地的15个草本植物群落为调查对象,研究河滨湿地不同草本植物群落的组成及多样性。结果表明,15个草本植物群落中共有31科73属94种植物,包括2科蕨类植物门植物和29科被子植物门植物,其中,禾本科植物最多(12属17种);丰富度最高的是狗尾草(Setaria viridis)群落;15个草本植物群落的Shannon-wiener指数介于0.22～2.07之间,人工群落荷花(Nelumbo nucifera)的Shannon-wiener指数最低,仅0.22,而另一人工群落水稻(Oryza sativa)的Shan-non-wiener指数却最大,达到2.07;典型湿地植物群落的Pielou均匀度指数较高,如扁秆藨草(Scirpus planiculmis)、芦苇(Phragmites australis)、水烛(Typha angustifolia)群落的Pielou均匀度指数都大于0.6;Simpson多样性指数最高的是荷花群落,而最低的是水稻群落;15个群落中,多样性指数、丰富度、均匀度指数和优势度指数在各群落间存在显著的差异;河滨湿地自然草本植物群落的Shannon-wiener指数、物种丰富度、Pielou均匀度指数均高于人工草本植物群落,而Simpson多样性指数则是前者低于后者,但人工草本植物群落与自然草本植物群落间4个多样性指数的差异并不明显。     

塔里木河中下游水分干扰对胡杨林群落物种多样性的影响

为探讨水分干扰对胡杨群落物种多样性的影响,以塔里木河(简称塔河)中下游胡杨林群落物种的实测数据为基础,选用群落物种多样性指数和相似性指数,对塔河中下游输水干扰后的样地和对照样地进行分析、研究。结果表明:(1)研究区内胡杨群落共包括14科、27属、27种,其中对照样地内植物物种数为11种,生态输水干扰的样地内植物物种数增长15种,总共26种;(2)对照样地和输水干扰样地Patrick丰富度指数、Simpson多样性指数、Pielou均匀度指数变化趋势不同,Pielou均匀度指数与Simpson多样性指数、Patrick丰富度指数相反,自中游到下游,物种多样性指数表现出差异,表明胡杨林物种在输水干扰后发生变化;(3)群落相似性比较表明,对照样地内胡杨群落相似性为中、下游临界点下游中游,对照样地与输水干扰样地相比,群落相似性结果相反。综上分析,认为水分干扰是影响塔河中下游胡杨群落物种多样性驱动因素。     

近50年海南岛红树林群落的变化及其与环境关系分析——以东寨港、三亚河和青梅港红树林自然保护区为例

选取海南岛东寨港、三亚河和青梅港红树林自然保护区为研究对象,在1959年和2008年的数据基础上,分析了近50年海南岛红树林种类、群落和面积的变化与环境之间的关系。在50年内,三地的红树植物相对灭绝种类比例小,只有三亚河种类变化较大,从26种减少为20种(另有2个引入种),东寨港和青梅港则分别仅减少1种。从群落类型面积变化分析可知,50年来三地主要群落的损失率均在41﹪以上,所毁灭的群落以近岸的内缘种为优势的群落为主,主要是海莲,尖瓣海莲,木榄群落和角果木群落等,并存在单优种群落向多种混合的多优种群落的演替,种群濒危,矮化和面积碎化现象突出。50年来三地红树林总面积也大为减小,东寨港和青梅港减少53﹪左右,而三亚河则减少92﹪。近50年来红树林的变化与环境关系表明,自然环境要素梯度变化形成了红树林群落空间分布和群落垂直分层的分异性。而社会(生产)环境要素的发展过程不但改变了红树林群落空间分布格局,还影响群落种群和外貌的趋同性。     

鄱阳湖湿地典型植物群落沿高程分布特征

鄱阳湖湿地植物群落沿高程呈现不规则的带状分异。利用遥感解译数据和数字高程模型,采用高斯回归方法,分析鄱阳湖湿地3种典型植物群落在全湖的分布特征及其在不同湖区的分布差异。结果表明,从全湖范围来看,茵陈蒿(Artemisia capillaris)—狗牙根(Cynodon dactylon)群落、芦苇(Phragmites australis)—南荻(Triarrhena lutarioriparia)群落、薹草(Carex spp.)—虉草(Phalaris arundinacea)群落分布的最适高程分别为14.3 m、13.2 m、12.5 m,依次降低;茵陈蒿—狗牙根群落的生态幅宽大于其它两种群落;与前人研究结果相比,3种群落的分布都有向低处延伸的趋向。从典型湖区的比较来看,3种群落在南矶湿地国家级自然保护区的分布高程都大于在鄱阳湖国家自然保护区的分布高程,高程差接近1 m。通过比较康山和都昌水文站的日平均水位发现,不同群落分布的高程差异及同一群落在不同湖区的分布差异与水文条件密切相关。本研究结果有助于认识大型湖泊湿地植物分布特征动态,对维护鄱阳湖湿地生态系统功能,降低区域生态灾害风险具有重要意义。     

盐城国家级珍禽自然保护区互花米草入侵后三种生境中越冬鸟类群落格局

互花米草(Spartina alterniflora)入侵沿海湿地后,会与本地植物进行竞争,从而形成本土植物与入侵植物群落共存的景观。对不同生境中鸟类群落格局的比较研究,有助于评估植物入侵对鸟类群落的影响。2014年11月中旬至2015年2月下旬,对盐城自然保护区核心区中心路南侧3种植物生境中越冬鸟类的种类、数量、鸟类觅食行为与基底等进行了研究。结果表明,3种生境中共记录39种鸟类。芦苇(Phragmites australis)群落生境越冬期鸟类均匀度指数、多样性指数和优势度指数最大,碱蓬(Suaeda glauca)群落生境、互花米草群落生境的3种指数依次减小。Jaccard相似性分析结果表明,互花米草群落生境与互花米草群落—芦苇群落交错带的鸟类群落极其相似;芦苇群落生境与碱蓬群落生境、互花米草群落生境的鸟类群落分别属中等不相似;碱蓬群落生境与互花米草群落生境的鸟类群落极不相似。棕头鸦雀(Paradoxornis webbianus)等8种鸟可以分别作为3种不同生境的指示种。在剩余信息40%的水平上,冬季鸟类群落可以聚为6个取食集团,除趋势对应分析排序结果表明,鸟类群落在轴1上可以分为3个类群。不同生境内的鸟类群落组成各异,且在不同生境有明显的指示种,鸟类群落的取食结构与生境内空间资源存在联系。在很多珍稀鸟类越冬过程中,本地物种碱蓬群落生境占据了重要地位,但是受芦苇群落和互花米草群落的双重竞争,其面积在逐渐减少,亟需加强保护与恢复。     

西洞庭湖不同生境下鸟类群落结构研究

为了研究人为干扰对西洞庭湖鸟类群落的影响,并提出相应保护对策,在2013年11月,采用样线法和样点法,对湖南省西洞庭湖国家级自然保护区内的鸟类群落结构进行了研究。在研究中,将该保护区的生境分为水域、天然洲滩、芦苇(Phragmites australis)丛、杨树林和居民区5种类型,前两种生境为天然生境,后3种生境存在人为干扰;记录了各生境下的鸟类种类、数量、行为等基本数据;计算了每种生境下的鸟类群落多样性指数、均匀度指数、优势度指数、种间相遇概率;对鸟类群落组成、数量进行了统计分析,对不同生境下鸟类群落结构进行差异性和相似性分析。结果表明,共记录到鸟类11目24科39种;其中,雀形目(Passeriformes)鸟种类最多,有8科15种;鹭科(Ardeidea)鸟种类最多,为4种;在地理分布型上,古北界鸟最丰富;在居留类型上,冬季以冬候鸟和留鸟居多,受保护鸟占总种数的一半以上;芦苇丛的鸟类群落的多样性、均匀性和种间相遇概率是5个生境中最高的,但优势度较低,水域、天然洲滩的鸟类群落结构多样性、均匀性和种间相遇概率都高于居民区和杨树林,但居民区和杨树林的鸟类群落优势度比其他生境高。因此,该保护区应该加大退林还湿、退田还湖的力度,以更好地保护湿地鸟类。     

塔里木河中游天然植物群落结构与数量特征分析

运用典型样地法,对塔里木河中游30个天然植被样地的群落结构和数量特征做了调查分析。结果表明:(1)塔里木河中游沙吉力克、沙子河、乌斯满、阿其河、铁依孜五个断面的天然植物隶属11科,20属,22种。(2)塔里木河中游植物群落结构可分三层,即乔木层、灌木层与草本层,但这种乔、灌、草的三层现象不明显。生境条件差,植物对环境利用不充分。(3)荒漠植物群落物种多样性水平较低,群落结构简单,物种组成单一。从多样性指数的数量特征来看,Simpson多样性指数的变化范围为0.47~0.609,Shannon-Wiener指数变化范围0.849~1.302;Menhinick丰富度指数的变化范围为2.309~3.175,Margalef 2.731~5.461;JSW均匀度指数的变化范围为0.6~0.778,JSI指数的变化范围0.633~0.805。五个断面盖度的变化范围是0.259~0.563。     

玉龙雪山植物物种多样性和群落结构沿海拔梯度的分布格局

生物多样性沿海拔梯度的变化是多样性环境梯度格局研究中的一个热点问题。在对滇西北玉龙雪山2 900 m~4 200 m间沿海拔梯度进行的群落调查基础上,对植物物种多样性和群落结构的垂直分异格局进行了分析。结果表明:1)在16个样地中共记录植物物种261种,分属78科,158属,其中木本植物36种,灌木植物71种,草本154种。2)沿海拔梯度,森林群落的最大树高、最大胸径、平均树高和平均胸径等群落结构指标均呈单峰分布格局。3)随着海拔的升高。木本和草本的物种丰富度,先增加后下降;而灌木层的物种丰富度随着海拔的上升呈明显下降格局。4)木本层和灌木层的β多样性(Cody指数)随海拔升高,总体呈减小趋势,而草本层β多样性显示出单峰分布的垂直格局。     

敦煌阳关国家级自然保护区湿地植物群落特征与物种多样性

敦煌阳关国家级自然保护区中的湿地是典型的内陆湿地,作为重要的候鸟迁徙驿站,具有脆弱性和特殊性,其植物群落特征与多样性研究对湿地及生物多样性保护有重要意义。通过野外样地调查,对阳关保护区湿地植物区系组成、地理成分和物种多样性进行了分析。结果表明,阳关保护区的湿地中共有74种植物,隶属于26科56属,其中占优势的是禾本科和藜科植物,二者占所有植物总物种数的29.73%;在植物生活型中,草本植物占绝对优势,占总物种数的77.03%;植物区系地理成分以温带分布型为主;用TWINSPAN分析法,将36块样地划分为8个植物群落,不同植物群落的物种多样性指数都较低,且存在较大差异;以重要值计算的Margalef丰富度指数为0~4.2,Simpson多样性指数为0~0.512,Shannon-Wiener多样性指数为0~1.4,Pielou均匀度指数为0.538~1,表明阳关保护区湿地植物种类总体上比较稀少、群落的组成和结构简单、物种多样性水平较低、生态较为脆弱。

Deserts and Aeolian Desertification in China: Book review and some thoughts

Desertification is a global phenomenon that affects about two billion people. It occurs in arid zones where the annual precipitation is below 400 mm, partic- ularly in the marginal areas of the world＇s largest deserts. It is a result of water and wind erosion, over- grazing, global warm-ing, improper soil cultivation, and increased pressure ot population growth, and it causes degradation of soil and natural and agricultural vegetation. The direct result is less food for people and livestock, which influences pop- ulation and animal husbandry fluctuations. Despite ef- forts to combat and reduce desertification, the affected areas are annually increasing.

THE MOST PERFECT EXAMPLE OF AN ALIEN ECOLOGY EVER CONSTRUCTED

Much science-fiction literature is based upon the creation and exploration of alternative environments. Stanley G. Weinbaum's short story, “Parasite Planet,”introduces an unusual environment that may be wrong in the light of recent evidence on Venus but still stimulates the geographical imagination.
