中国体质人类学百年回顾
Review on History of 100 Years of Physical Anthropology in China
 [PDF]

Modern Anthropology (MA) , 2013, DOI: 10.12677/MA.2013.12002
Abstract:

本文对体质人类学在中国的百年发展历史进行回顾,把体质人类学在中国的发展历史分成四个时期:即19、20世纪之交至20世纪20年代末的传入和接受时期,20世纪30年代至1949年的本土化时期,1949年至1976年的曲折发展时期,20世纪70年代末以来的纵深发展时期,并且对各个发展时期的重要事件进行了回顾。

In this paper, the author reviewed the history of physical anthropology in China and divided it into four stages: 1) introduction and acception stage (from the turn of 19th and 20th centuries to 1920’s), 2) localization stage (from 1930’s to 1949), 3) circuitous stage (from 1949 to 1976) and in-depth stage (from 1976 to now) and described the important incidents in different stages.

全球变暖对我国西北地区小麦生产的影响
The Impact of Global Warming on Wheat Yields in Northwest China
 [PDF]

Climate Change Research Letters (CCRL) , 2012, DOI: 10.12677/CCRL.2012.12006
Abstract: 本文利用西北五省()1978~2007年小麦生产的投入产出数据和气候数据,研究了全球变暖对该地区小麦生产的影响。结果表明,年平均气温上升1%,小麦产量下降0.023%,而年降水量和年日照时数的变化对小麦生产没有显著影响。为了应对全球变暖对西北干旱地区粮食生产的负面影响,有必要从耕作实践、良种培育、土地利用、防灾减灾等方面探索有效的适应性措施。
 

Using the input-output data of wheat production and climate data in five provinces of northwest Chinaduring 1978-2007, this paper studies the impact of global warming on the wheat yields in northwestChina. It concludes that the annual average temperature rises one percent, the wheat yields will reduce by 0.023%, while there is no significant impact of annual precipitation amount and annual sun-shining hours on wheat yields. In order to counter the impact of global warming on wheat production in northwestChina, it is necessary to explore the adaptive measures in farming practice, seed cultivation, use of arable land, and the prevention and mitigation of agricultural disaster.

Abstract: 概述了用颜色立体模型表示物体颜色,并做定量表示的颜色体系研究的理论意义及应用价值。介绍了国际上影响较大的颜色体系理论和编制原则的特点。中国颜色体系研究是在对国际上其它颜色体系的理论分析和对颜色样品测试的基础上,确立其理论依据和编制原则,开展了中国人眼对明度、色调、彩度等间距排列的视觉评价实验,建立了中国颜色体系理论模型。同时研制出《中国颜色体系样册》。该项研究于1993年7月通过了国家自然科学基金委员会和中国科学院联合召开的成果鉴定会,并得到良好的评价,又于1994年6月通过国家标准审查。该项研究的完成和推广,不仅能为我国国民经济各部门的颜色控制、标定和交流提供科学的颜色定量手段,同时也是对实用色度学的发展和颜色标准化工作做了有益的工作,产生了积极的经济效益和社会效益。

Recognition and proposal on the vegetation classification system of China
对中国植被分类系统的认知和建议

SONG Yong-Chang,

植物生态学报 , 2011,
Abstract: An encyclopedia of Chinese vegetation is going to be compiled as a series of books, and comments are sought to revise the “Vegetation Classification System of China” (VCSC). These require several key decisions. First, the principle of VCSC proposed by Vegetation of China (1980) that “the higher rank of classification unit would be based on the physiognomy of vegetation, while the middle and lower rank emphasized on species composition and community structure” should be maintained because it is corresponding with the current trends of international vegetation classifications. Second, VCSC should classify Chinese vegetation to be compatible with global vegetation classification, so that the terms and concepts will be widely accepted internationally. Third, “Association”, a fundamental classification unit described by the series of books of Chinese vegetation, should be defined and used consistently, so that misunderstandings between northern and southern associations can be avoided. Fourth, the hierarchy in the classification of vegetation generally should be rigid, but different ranks remain open and flexible, i.e., upper-level units can be supplemented to meet future needs. A draft of the VCSC (from class to vegetation type) is proposed in this paper.

Abstract: 1993年至2008年是中国蛋化石研究不断扩展与深入的时期。这期间的研究更注重于解决盆地地层与蛋化石演化序列间的联系; 开展了翼龙化石胚胎学研究; 通过分子古生物学分析, 尝试了获取古代DNA的方法; 河南西峡恐龙蛋化石博物馆的建立, 成为展示这一阶段进展的突出标志。特别是近几年来, 通过大量资料积累, 发现并揭示出恐龙蛋的变异类型与鸟蛋间的联系, 由此填补了从恐龙到鸟的演化过程中蛋壳形态结构变化的空白。文中还介绍了我国白垩纪几个沉积盆地的生物地层和一些具有特色的蛋化石种类; 提出了新的蛋化石分类意见, 以及与蛋化石有关的生存行为方面的思考。

地理学报 , 2006,
Abstract: Using foggy days and mean temperature and relative humidity of 602 stations from January to December in the period 1961-2003 in China, the relationship between variations of foggy days and temperature and its possible reason for 43 years were analyzed by regression, correlation and contrastive analysis methods. The results show that the higher (lower) the mean temperature and relative humidity, the lower (higher) corresponding to the less (more) foggy days, the relationship is best in the western, northern, eastern Sichuan, the Yunnan-Guizhou Plateau, and southeast highland in China. This induces a decrease in relative humidity when the climate becomes warmer, and eventually brings about a decrease in foggy days in China.
