Speculating on the origin of Gaultheria, two different hypotheses were suggested, one of Gondwanan origin, and the other of Laurasian origin In the present paper, recent advances in molecular phylogenetics and biogeography of Gaultheria are summarized and some problematical issues within the genus discussed.

关於白珠树属的起源问题存在两种不同的推测：一种观点认为该属起源於南半球的冈瓦纳古陆；另一种观点则认为其起源於北半球的劳亚古大陆。本文概述了近年来白珠树属的分子系统学和生物地理学研究进展，并对该属尚存的一些问题进行了讨论。

The main results are listed as following: 1. Phylogeographic study on Croomia The relationships and distribution of cpDNA haplotypes suggested that Croomia had been widely distributed in ancient eastern Asian and northern American; the origin and distribution center of Croomia were concentrated on the mountains comprised Mt.

Croomia亲缘地理学根据叶绿体DNA(trnL-F、atpB-rbcL)单倍型的关系和分布推测，Croomia在古欧亚大陆和古北美大陆有着较广泛的分布；我国的黄山和天目山一带是Croomia的分布、起源中心，其散布路线是从中国大陆到日本，再到美洲古大陆；北美种群与东亚种群分离较早；东亚种的分化时间比较晚。

It is the journal of the Palaeontological Association.

The development of modern computer and information technology provides a series of new methods for palaeogeographic research.

现代计算机和信息技术的飞速发展为古地理学研究提供了一系列新的研究手段。

New palaeogeographic theory and technical progress play very important roles in exploration and development of sedimentary mineral resources.

古地理学的理论发展和相关的技术进步在勘探开发沉积矿产资源等方面发挥了重要作用，开拓了在河流、三角洲及滑塌浊积扇、深水重力流沉积、滩坝、礁以及碳酸盐岩建隆中找油的新领域。

The syncretism of palaeogeographic research and information technology can lead to the advancement of the research method and quality, it can also supply effective technology supports for sedimentary mineral deposits in geological history.

古地理学研究与信息技术的融合不仅能使研究手段和水平得以提升，还能更好地为地质历史时期中沉积矿产勘查提供有效的技术支持。

Palaeogeography of China shows 4 main tendencies, i.e. from single to comprehensive, from qualitative to quantitative, from manual mapping to computer mapping, and from theory to practice.

我国的古地理学有 4个主要的发展趋势，即从单一到综合，从定性到定量，从手工作图到计算机作图，从理论到应用。

At the ceremony of this conference, the author especially honors and thanks many pioneers, specialists and scholars, such as Grabau A.W., Huang T.K., Hsiech C.Y., Liu Hongyun, Guan Shicong, Wang Hongzhen, Liao Shifan and so on. They made the pioneering contributions and achievements to palaeogeography of China.

在这一盛会的开幕式上，作者特别怀念和感谢往昔从多的老前辈、专家和学者，如葛利普、黄汲清、谢家荣、刘鸿允、关士聪、王鸿祯、廖士范等，他们对我国古地理学作出了开拓性的贡献和功绩。

Cynanchum Lingtai apricot production in the average weight 65 grams, the brightly-colored fruit, juicy rich, sweet-sour taste, sweet from the nucleolus, when the late Qing Dynasty famous Shaanxi, Gansu provinces, the Qing imperial court Tongzhi tribute for years.

灵台生产的牛心杏平均单果重65克，果实色泽鲜艳，汁多味浓，甜酸适口，离核仁甜，清末时就驰名陕、甘两省，清同治年间曾为朝廷贡品。

Chenopodium album,Solanum nigrum, and Amaranthus retroflexus were very susceptible to the herbicides. Polygonum persicaria and Abutilon theophrasti were relatively less susceptible to the herbicides, and Lycopersicon esculentum was not susceptible to it. The relationship between reduction rates of weed biomass and PPM values of weed leaves 2,4, and 6 days after treatment was established.

供试的6种杂草对该混剂的敏感性存在显著差异：红心藜Chenopodium album、龙葵Solanum nigrum和反枝苋Amaranthus retroflexus对该混剂最敏感，ED90值分别为47.65、71.67和29.17g/hm2；春蓼Polygonum persicaria和苘麻Abutilon theophrasti敏感，ED90值分别为96.91、114.20g/hm2；而番茄不敏感。
