兴隆山自然保护区蜘蛛区系的研究

１９９２－１９９３年间进行兴隆山自然保护区蜘蛛区系的研究，共获标本１４４０号，初步鉴定为９１种，４５属１５科，其中古北界的种类为４６种，占总种数的４０．５４％，东洋界的种类为５种，占总种数的５．４９％，广布种为４０种，占总种数的４３．９５％。显然，古北界的种类占优势。     

前寒武纪的划分

本文采用尹赞勋提出的地球历史发展的两大阶段:天文时期与地质时期,并同意废弃隐生宙与显生宙。本文着重讨论了生物的发展,从无机到有机,到蛋白质,到细胞,到后生动物的阶段性。建议地质时期代的划分,根据生物发展阶段特征,前寒武纪划分为无生代、隐生代、始生代与原生代。另把古生代下限延至900Ma,包括震旦纪。小壳动物应归属震旦纪,而不是寒武纪。     

系统地理学的研究及其在鱼类上的应用

介绍了系统地理学的研究内容、理论、方法,重点介绍了AVISE的5种物种分布模式、中性溯祖理论、mtDNA多态性分析的优越性以及TEMPLETON的巢式支系法。还从地理隔离、种群扩散、基因交流、区系划分、分子钟估算等方面阐述了系统地理学在鱼类的应用研究现况和应用前景。最后提出了系统地理学在鱼类应用时要注意的事项:1)要选择合适的基因DNA片段进行分析;2)mtDNA标记最好要与核DNA标记及形态学、细胞学、生化学标记结合使用;3)要提高分子钟估算的精确度。     

中国北方新近纪红黏土记录的古气候意义——与动物群化石序列对比

目的研究中国北方新近纪红黏土序列的古气候演化特征。方法对中国北方4个新近纪红黏土剖面沉积物的粒度、磁化率和化石动物群时间序列进行区域对比。结果黄土高原新近纪红黏土沉积以来发生了5次大的气候事件,气候事件的分界线在粒度、磁化率年龄曲线上特征明显,反映的气候特点与化石动物群演替性质完全一致。结论中国北方新近纪红黏土序列古气候演化过程的气候事件均与青藏高原隆升和东亚季风的发展相联系。时间上,南北气候演化事件基本同步;空间上,北部较南部地区变化剧烈。5次气候事件从下到上表现为半湿润、半干旱、湿润、干旱与湿润交替、干旱的气候演化特征;相应动物群生态类型表现为草原-疏林草原、草原为主的疏林草原、森林、草原荒漠与森林交替到草原的演化特点。     

Taxonomy, age and environment status of the Yuanmou hominoids

When, where and from which hominoid the human originated has been one of the key subjects in the study of human natural history. It is therefore very important to learn the chronological, geographical and taxonomic distribution of all hominoids. Yunnan Pr…     

甘肃西部蝶类区系研究

1994－1998年7－8月间广泛收集到甘肃西部地区蝶类标本1200多号：经鉴定为127种及亚种，隶属于8科，73属：其中有44种及亚种为甘肃省新记录；经区系分析属于古北界种74种，占总数的58．8％，广布种为53种，占总数的41．2％，古北界占优势。     

广西森林溪流淡水鱼类区系研究

通过调查发现，分布于广西森林溪流中淡水鱼类有92种，分别隶属于5目、16科、63属。鲤形目占64．1％，鲇形目占11．96％，鲈形目占20．65％，合鳃目占1．01％，Jiang形目占2．72％。其中鲤科鱼类占总种数的46．7％。可划分为热带平原、江河平原、中印山区、上第三纪、北方平原5个区系复合体。在不同的海拔高度鱼类分布不同，具有明显的山区特征，广西森林溪流淡水鱼类区系形成与广西自然环境的历史演变有密切关系。     

The ecological sequence of Hipparion fauna in the mid-dle reaches of the Yellow River during Neogene

The faunal ecological type and sequence in the Tertiary red clay indicate that Hipparion fauna during the period 7.4-6.1 Ma in the middle reaches of the Yellow River is composed mainly of dorcadoides and mixed types. This represents semiarid veld environment with small fluctuation. The fossil assemblages characterized by the abundance of gaudryi types and even the occurrence of some Hominoid and Chalicotherium indicate an obviously warm and humid period since 5.3 Ma. The fossil assemblages during 3.4 Ma show the typical steppe fauna representing dry climate. It is indicated by the changes of ecological sequence that the climatic conditions in Pliocene are drier than that in late Miocene. The clay-skin content of red clay, which has a synchronous change with faunal features, is a rather good replacing palaeoclimatic index.
