四川水稻定向引种诊断系统及其气候生态模型

介绍了四川水稻定向引种诊断系统（DSIRV）的设计思路，以及建立水稻气候生态、栽培模型的依据和方法。该系统在四川已投入生产应用，其引种诊断成功率达70%以上，比常规品比法进行引种缩短周期2—4年。     

Numerical Simulation of Regional Short-Range Climate Anomalies

With the high-speed development of numerical weather prediction, since the later 1980’s, the prediction of short-range climate anomalies has attracted worldwide meteorologists’ attention. What the so called short-range re-fers to the time scale from one month to one season or more. In dealing with the problem of short-range climate pre-diction, two points are needed noticing: one is the basic research to explore or investigate the mechanism of variability of the slow varying components which mainly include internal dynamics of extratropics, external forcings and tropical dynamics, and the other is the modeling efforts to simulate the process of the long-term evolution of the signal which include the improvement of model quality, stochastic prediction and the air-sea-coupled model (Miyakoda et al.,1986). Previous researches on the numerical prediction of short-term climate anomalies are mostly concentrated in the analysis of variables with global spatial scale, especially the global general atmospheric circulation analysis.As to the simulation or prediction of regional short-term climate anomalies, there exist many difficulties and problems. Though some meteorologists are devoting themself to this field, up to now, they have not reached satisfac-tory results. As a primary effort, by using the 2-level general atmospheric circulation model developed in the Institute of Atmospheric Physics, Chinese Academy of Sciences (IAP-AGCM) (Zeng et al., 1989), and taking the year of 1985 as a case, a numerical simulation of regional short-term climate change is completed. We pay high attention to the predictand of anomalous summer rainfall in the Yangtze River and Yellow River valleys, especially its month-to-month variation.

三门峡盆地第四纪古地理演变与古人类活动

三门峡盆地位居黄河中游,环境的演进与古人类的活动有着密切关系。早更新世,三门峡盆地为湖盆区,在盆边林缘地带发展了西侯度文化;中更新世,盆地内山前洪积扇面积扩大,湖盆缩小,扇前近水地带发展了匼河一丁村文化;晚更新世,湖水消失,黄河出现,黄土堆积的山麓与河谷两岸阶地上,发展了许家窑文化;全新世,大陆性季风明显,黄土丘陵与河谷阶地区发展了仰韶文化、龙山文化与现代人类社会历史。可见,盆地区古人类活动历史已长达200万年左右。而且,人类的发展迁徙与古地理环境的演进也是有着密切关系的。     

闽粤台沿海北西西向最新构造带与大震构造背景

闽粤台沿海自台湾运动以来逐渐形成了多条北西西向隆起—拗陷的最新活动构造带,与已知的北东—北北东向隆起、拗陷带构成了区域性镶嵌构造格局。 研究区内除板块相互碰撞、俯冲及上地幔物质上涌形成大震构造背景外,莫霍面隆起或隆起断距大、低速层厚、地壳变薄、近两、三千年地表抬升差异活动显著以及台东近海有北西西向构造活动等,也都是发生大震的重要构造背景     

Spectroscopic Study of Natural Diamonds in China

It has become clear in recent years that the important substitutional impurities in diamond are nitrogen,hydrogen and boron(Bibby,D.M.,1982).The physical and chemical properties of diamond are determined by the content and form of occurence of nitrogen based on which diamonds are generally classified.The well-known experiments concerning the mutual transformation of the forms the origin of diamond.by Evans.T.Et al.(1982) have provided a theoretic basis for the origin of diamond.Since 1979,spectroscopic investigation of natural diamonds from different areas in china has been carried out using UV-visible and IR spectrophotometer,EPR and cathodoluminescence techniques.We have conducted the classification of natural cathodoluminescence techniques.We have conducted the classification of natural diamonds in China and studies on the forms of nitrogen and hydrogen,the radiation damage and their geological implications.Spectroscopic characteristics of natural diamonds in china and their geological implications are discussed in this paper.
