Biogeographical Divergence of the Flora of Yunnan,Southwestern China Initiated by the Uplift of Himalaya and Extrusion of Indochina Block

The floral composition of Yunnan is conspicuously linked to the biogeographical history of this extremely species-rich province in southwestern China. The floristic compositions of three representative regions in Yunnan were compared to reveal their variation with geography. From southern Yunnan, 4150 native species (including subspecies and varieties) from 1240 genera and 183 families of seed plants were recognized. From central Yunnan 3389 native species from 1095 genera and 167 families of seed plants were recognized. From northwestern Yunnan 6807 native species from 1296 genera and 166 families of seed plants were recognized. Although these three floras across Yunnan are similar in familial composition, similarities between the floras of southern and northwestern Yunnan are low at the generic and specific levels. The flora of northwestern Yunnan is dominated by families and genera with cosmopolitan and north temperate distributions, while the flora of southern Yunnan is dominated by tropical families and genera. Northwestern Yunnan is composed largely of temperate genera, of which the highest proportion has a north temperate distribution. In contrast, southern Yunnan has mainly tropical genera, of which most have a tropical Asian distribution. The flora of central Yunnan is a combination of southern and northwestern Yunnan. These three floras might be derived from a common Tertiary tropical or subtropical East Asian flora, but the geological history of each region has influenced its flora, and they have remained divergent since the late Tertiary. The flora of northwestern Yunnan has evolved with the uplift of the Himalayas and by gradual proliferation of mainly cosmopolitan and north temperate floristic elements, while the flora of southern Yunnan has evolved with extrusion of the Indochina block and the influence of mainly tropical Asian elements.     

滇东南和滇西北国家重点保护野生维管植物比较分析

通过野外考察和资料整理,对《国家重点野生保护植物名录(第一批)》中维管植物在滇东南和滇西北的空间分布及其与保护区设置的相关性进行统计和分析。结果表明:1、滇东南有107种保护植物,占云南分布(144种)的74.31%;滇西北53种,占云南省的36.81%;2、滇东南和滇西北保护植物种类垂直分布均呈单峰曲线,滇东南集中分布在海拔1008m附近(RSE=0.9919),滇西北主要在2 360 m附近(RNW=0.9656);3、县级水平的自然保护区设置权重与国家I级(Pearson指数,rI=0.724)和Ⅱ级(rⅡ=0.643)保护植物种类在滇东南均呈极显著的正相关性(P0.01),而在滇西北相关性(rI=0.464;rⅡ=0.410)差异均不显著(P0.05)。滇东南保护植物较滇西北丰富,滇东南保护区设置较滇西北更有利于对保护植物的有效保护。     

云南植物区系的起源与演化

云南是生物多样性高度富集的地区,其植物种类占中国植物种类的一半以上,几乎包含了欧亚大陆的各种主要植被类型,其错综复杂的生物区系是如何形成与演化的,这个基本问题目前尚未得到解决。本文结合云南的历史地质事件,从植物区系地理学研究上对云南植物区系的起源与演化研究进行了介绍。研究发现,云南植物区系具有一个远古的热带起源背景,在第三纪热带、亚热带性质的东亚植物区系基础上,随着喜马拉雅的隆升,世界性和北温带植物区系成分在北部地区渗透、迅速形成大量物种,使北部地区演化成为现今以世界性和北温带分布的科、属占优势的温带植物区系;在南部地区,因印度支那地质板块向东南亚逃逸,热带亚洲成分渗透、发展,演化成为以热带亚洲成分为主的热带植物区系;云南中部地区第三纪东亚植物区系成分有更多的保持与承袭。对云南南部、中部和北部植物区系系统发育关系(系统发育结构和β多样性格局)的研究支持了植物区系地理学上的推论。此外,思茅-兰坪(印度支那)地质板块自晚始新世以来发生顺时针旋转可能导致了云南西北部与云南东南部一些物种对应分布格局的形成;云南南部与东南部热带地区的植物区系可能因具有不同的地质背景和演化历程而发生了显著的生物地理分异。在晚第三纪各地质事件的影响下,云南植物区系在一个热带、亚热带性质的第三纪东亚植物区系基础上发生了歧化,演化成为现今的南-北、东-西生物地理分异明显的植物区系。

Contribution to knowledge of the genus Chydaeus in Xizang Autonomous Region [Tibet] and Yunnan Province, China (Coleoptera, Carabidae, Harpalini)

Five new species of the genus Chydaeus Chaudoir, 1854 are described from China: Chydaeus fugongensissp. n. (Shibali, Fugong County, Yunnan Province), Chydaeus gutangensissp. n. (Gutang, Medog County, Xizang Autonomous Region [Tibet]), Chydaeus hanmiensissp. n. (Hanmi, Medog County, Xizang Autonomous Region [Tibet]), Chydaeus asetosussp. n. (NE of Fugong, Yunnan Province), and Chydaeus baoshanensissp. n. (N of Baoshan, Yunnan Province). Taxonomic and faunistic notes on eleven other species occurring in Xizang and Yunnan are also provided. Chydaeus shunichii Ito, 2006 is re-described, based on specimens from Lushui County, Yunnan. Chydaeus kumei Ito, 1992 is treated as a subspecies of Chydaeus andrewesi Schauberger, 1932 [NEW STATUS]. The taxonomic status of Chydaeus guangxiensis Ito, 2006 is discussed. The following taxa are recorded from China for the first time: Chydaeus obtusicollis Schauberger, 1932 (Xizang and Yunnan), Chydaeus malaisei Kataev & Schmidt, 2006 (Yunnan), Chydaeus semenowi (Tschitschérine, 1899) (Xizang and Yunnan), Chydaeus andrewesi andrewesi Schauberger, 1932 (Xizang and Yunnan), Chydaeus andrewesi kumei Ito (Yunnan), Chydaeus bedeli interjectus Kataev & Schmidt, 2002 (Xizang), and Chydaeus bedeli vietnamensis Kataev & Schmidt, 2002 (Yunnan).

云南主要有害实蝇种类及区划

采用诱剂诱捕辅以受害瓜果调查的方法,系统梳理了云南有害实蝇类群,确定主要有害种类25种。基于云南自然地理特征,采用聚类分析法深入探讨了云南实蝇区系,提出云南实蝇地理区划可分为德宏、版纳盆谷区,南部边缘中低山宽谷区,滇西南山原峡谷区,中东部高原、岩溶山原区以及北部高原山地区等5大区域。研究发现,受热量条件制约,云南主要有害实蝇类群呈南北向梯度递减;受纵向岭谷区"通道-阻隔"综合作用影响,云南西南部河谷地区是实蝇危害较为严重的区域。首次系统揭示了云南主要有害实蝇的地理分布规律。     

云南省粘虫二代虫源探讨

首先设定常年有一代粘虫发生的印度北部、云南省和我国江淮地区为云南省粘虫主害代（二代）的可能虫源地。然后,讨论各个可能虫源地一代粘虫发生量及迁出时期空中走廊气流方向和强度对云南省二代粘虫发生量的影响;分析云南二代粘虫迁入期与各个一代区成虫迁出期的对应关系。结果表明：云南二代粘虫虫源主要来自于江淮地区一代粘虫发生区;小部分来自于云南一代粘虫发生区,但其基数甚小,仅此成分不致造成对作物的危害;没有包含印度一代粘虫的成分。此结论在1994～1995年的异地测报应用中得到验证。

Cenozoic plant diversity of Yunnan: A review

Yunnan in southwestern China is renowned for its high plant diversity. To understand how this modern botanical richness formed, it is critical to investigate the past biodiversity throughout the geological time. In this review, we present a summary on plant diversity, floristics and climates in the Cenozoic of Yunnan and document their changes, by compiling published palaeobotanical sources. Our review demonstrates that thus far a total of 386 fossil species of ferns, gymnosperms and angiosperms belonging to 170 genera within 66 families have been reported from the Cenozoic, particularly the Neogene, of Yunnan. Angiosperms display the highest richness represented by 353 species grouped into 155 genera within 60 families, with Fagaceae, Fabaceae, Lauraceae and Juglandaceae being the most diversified. Most of the families and genera recorded as fossils still occur in Yunnan, but seven genera have disappeared, including Berryophyllum, Cedrelospermum, Cedrus, Palaeocarya, Podocarpium, Sequoia and Wataria. The regional extinction of these genera is commonly referred to an aridification of the dry season associated with Asian monsoon development. Floristic analyses indicate that in the late Miocene, Yunnan had three floristic regions: a northern subtropical floristic region in the northeast, a subtropical floristic region in the east, and a tropical floristic region in the southwest. In the late Pliocene, Yunnan saw two kinds of floristic regions: a subalpine floristic region in the northwest, and two subtropical floristic regions separately in the southwest and the eastern center. These floristic concepts are verified by results from our areal type analyses which suggest that in the Miocene southwestern Yunnan supported the most Pantropic elements, while in the Pliocene southwestern Yunnan had abundant Tropical Asia (Indo–Malaysia) type and East Asia and North America disjunct type that were absent from northwestern Yunnan. From the late Miocene to late Pliocene through to the present, floristic composition and vegetation types changed markedly, presumably in response to altitude changes and coeval global cooling. An integration of palaeoclimate data suggests that during the Neogene Yunnan was warmer and wetter than today. Moreover, northern Yunnan witnessed a pronounced temperature decline, while southern Yunnan experienced only moderate temperature changes. Summer precipitation was consistently higher than winter precipitation, suggesting a rainfall seasonality. This summary on palaeoclimates helps us to understand under what conditions plant diversity occurred and evolved in Yunnan throughout the Cenozoic.
