从太湖流域旱涝史料看历史气候信息处理

历史气候信息处理建立在信息提取的基础上,目的在于建立一套方法,将定性的历史气候信息转化为气候变化参数,并消除各种不均—性,从而建立历史气候序列。本文着重介绍建立太湖流域历史旱涝等级序列的方法与步骤: 1)确立信息源,建立信息网络;2)站点等级的确定与订正;3)弱信息处理;4)信息的综合。     

The Cenozoic Volcanoes in Northeast China

There are more than 600 Cenozoic volcanic cones and craters with abeut 50 000 km2of lava flows in northeast China, which formed many volcanic clusters and shown the features of the continental rift - type volcanoes. Most volcanic activities in this area, especially in the east part of Songliao graben, were usually controlled by rifts and faults with the main direction of NE / NNE in parallel and become younger from the central graben towards its both sides, especially to the east continental margin. It is revealed that the volcanism occurred in northeast China was as strong as that occurred in Japan during the Miocene and the Quaternary. The Quaternary basalt that is usually distributed along river valley is called "valley basalt"while Neogene basalt usually distributed in the top of mounts is called "high position basalt". These volcanoes and volcanic rocks are usually composed of alkaline basalts with ultramafic inclusions, except Changbaishan volcano that is built by trachyte and pantellerite.

闽南-台湾浅滩渔场浮游软体动物的分布

本文分析了1987年12月至1988年11月在闽南-台湾浅滩渔场6个航次采集的浮游软体动物,初步鉴定44种,以马蹄(?)螺、棒笔帽螺、尖笔帽螺和蝴蝶螺为该海区的优势种。本文研究了它们的季节变化,平面分布和垂直分布,并讨论了它们与上升流及其他水系的关系。     

Variational iteration solving method for El Nio phenomenon atmospheric physics of nonlinear model

1 IntroductionThe El Ni’o atmospheric physics oscillation is anabnormal phenomenon involved in the tropical Pacificocean- atmosphere interactions. Studies on the El Ni(ophenomenon are very attractive (Lin et al., 2000; Linet al., 2001, 2002; Wang, 2001; Feng et al., 2001;Feng et al., 2002; Liu et al., 2002; Wei and Chen,2003; Xie et al., 2002; Zhu et al., 2002; Pu et al.,2003; Gu et al., 2004; Yu and Liu, 2004).

台湾海峡及其邻近海域中华哲水蚤的分布和繁殖

中华哲水蚤(Calanus sinicus Brodsky)是我国近海的优势桡足类。它的数量大，分布广。特别在冬、春季，在我国近海浮游动物中，占有相当大的比例；同时它的个体也较大，是滤食性种类。因其在海洋生态系统的物质循环和能量流动中，起着相当的作用，所以被国家自然科学基金重大项目-“东、黄海生态系统动力学与生物资源可持续利用”课题定为浮游动物的关键种之一。 作者根据以往历史资料(方金钏，1979；朱长寿，1997；朱长寿等，1991、1999；林玉辉等，1988；林元烧等，1984；李少菁，1963；陈清潮，1964；福建省海岸带和海凃综合调查领导小组，1990；福建海洋研究所，1988；Tan，1970)和多年来的研究结果(黄加祺等，1984，1986a、b、c，1989，1991a、b，1997a、b)，对中华哲水蚤在不同水域的分布，与温、盐度关系及繁殖进行了探讨，并提出见解，为本项目子课题提供了历史资料。     

福建罗源湾浮游桡足类的分布

本文利用1986年11月至1987年10月在福建罗源湾采集的浮游生物样品,分析研究了该海区桡足类的种类组成和数量分布。结果表明,其优势种大网为中华哲水蚤、亚强真哲水蚤、真刺唇角水蚤和太平洋纺锤水蚤,中网为强额拟哲水蚤、小型拟哲水蚤、短角长腹剑水蚤。桡足类总量年高峰大、中网分别为2个和1个。中网桡足类与叶绿素a、温度和盐度等因素显著相关。     

罗源湾水母类的生态研究

样品于1986年11月至1987年10月在福建省罗源湾10个站位采集。经鉴定有52种水母。它们可分为沿岸暖水、沿岸暖温和大洋广布三种生态类群。水母类总数量和种类数的季节分布呈单周期,两者高峰均出现在7月。低谷分别出现于11月和1月。在平面分布上,以拟细浅室水母Lensia subtiloides占优势的月份,数量从湾口向湾顶递减,而以球型侧腕水母Pleurobrachia globosa占优势的月份,数量却递增。文中还讨论了水母类的分布和环境因素的关系。     

Effect of volatiles erupted from Mesozoic and Cenozoic volcanic activities on paleo-environmental changes in China

Based on the determination of composition of volcanic volatiles and petrologic estimation of the total mass of volatiles erupted, we showed important advances in the study of the impact of Mesozoic and Cenozoic volcanic activities on paleo-environmental changes in China. The volcanic activities include western Liaoning and Zhangjiakou Mesozoic intermediate-acidic explosive eruptions, southern Tibet and Shanwang Cenozoic volcanism, and Mt. Changbai volcanic eruption around one thousand years ago. The paper predominantly discusses the earth’s surface temperature changes, ozone depletion, acidic rain formation and mass mortalities of vertebrate induced by the Mesozoic and Cenozoic volcanism in China. __________ Translated from Bulletin of Mineralogy, Petrology and Geochemistry, 2007, 26(4): 319–322 [译自: 矿物岩石地球化学通报]
