滴哨沟湾地层沉积特征记录的毛乌素沙漠变迁

毛乌素沙漠的盛衰变化明显地受到全球变化特别是东亚夏季风变化的影响。根据毛乌素沙漠东南缘萨拉乌苏河流域滴哨沟湾地层沉积物的物质组成、粒度参数等,结合孢粉研究结果,将沙漠演化过程划分为若干阶段：中更新世晚期沙漠萎缩期,气候温暖半干旱-半湿润,沙漠缩小,为森林草原或灌丛草原;中更新世晚期沙漠稳定期,气候在寒冷干旱-半干旱间波动频繁,自然景观在荒漠、荒漠草原与干草原间变化,并有河流和小湖存在;晚更新世早期沙漠固定期,气候温暖半湿润至半干旱,期间自然景观经历了森林草原、灌丛草原、草原、荒漠草原多种变化;晚更新世晚期沙漠扩张期,气候干旱寒冷,自然景观以荒漠和荒漠草原为主,同时也有草原乃至灌丛草原出现;全新世沙漠频繁变化期,气候变化频繁,沙漠出现多次盛衰变化,自然景观在荒漠、荒漠草原、草原、疏林草原间变化。     

科尔沁沙地南缘虻石沟黄土地层孢粉分析与古环境的探讨

本文通过对科尔沁沙地南缘虻石沟黄土地层孢粉分析, 划出四个花粉带。Ⅰ带是榆, 榛, 蒿; Ⅱ和Ⅳ带是蒿、藜; Ⅲ带是蒿、菊科、禾本科。从中更新世至晚更新世期间植被与气候变化, 经历了榆树疏林草原(温和偏湿)→半荒漠草原(干冷)→干草原(温凉稍湿)→半荒漠草原(干冷)多次变化过程。孢粉分析表明, 我国北方黄土地层孢粉沮合特点, 由种类贫乏喜干旱的草本花粉组成, 木本花粉数量很少, 反映黄土堆积的干燥气候占主导。植被景观多半是森林草原, 疏林草原, 干草原, 榆树疏林草原, 半荒漠草原或荒漠草原型植被。     

萨拉乌苏河地区晚更新世环境演化

对萨拉乌苏河地区上更新统地层作进一步划分的基础上,本文论述本区晚更新世前期萨拉乌苏组沉积时的古地理环境为暖湿的森林草原.后期城川组主要形成于干冷的荒漠草原-荒漠环境,期间经历了一系列温凉湿润的灌丛草原-疏林草原、森林草原等环境的交替演化过程.     

萨拉乌苏河地区晚更新世以来的孢粉组合及其反映的古植被和古气候

本文通过对萨拉马苏河地区晚更新世以来46块地层样品的孢粉分析,共鉴定统计孢粉10390粒,其中木本植物花粉2759粒,草本及小灌木花粉7558粒,蕨类孢子73粒,分属于61个科属。根据其组合特征可划分五个孢粉组合带。反映该区自晚更新世以来植被类型曾经历了针阔混交的森林草原→荒漠草原→有松、冷杉、云杉针叶林的森林草原→荒漠草原→草原→疏林草原→草原多次演替,该区气候出现温暖湿润→于冷多风→温凉湿润→更干冷、多风→干冷→温凉偏湿→较干冷等→系列更替。     

松嫩沙地晚更新世以来的孢粉记录及古植被古气候

松嫩沙地的形成演化经历了一个漫长的地质历史过程, 孢粉记录反映出这个地区从晚更新世以来植被曾被发生过多次更替, 经历了半荒漠(半荒漠草原)→疏林草原→干草原的演替, 气候经过多次冷暖-干湿波动, 沙漠化也经历了多次扩张和收缩。与中国北方其它沙漠化土地一样, 气候变干是松嫩沙地形成和扩张的决定因素, 而人类的各种活动对这一地区的土地沙漠化起着诱发和促进作用     

黄土高原350～280ka PB气候迁移研究

根据野外调查和室内鉴定、分析了黄土高原350~280 ka PB前后的气候迁移变化问题。资料表明,在地处黄土高原南缘的陕西长安少陵塬第3层古土壤形成中晚期和第4层古土壤形成的早期有代表荒漠草原环境的石膏发育,指示当时黄土高原气候发生了显著的干旱化与大幅度的荒漠草原南迁,与现在这个地区气候相比,气候带向南迁移了约4个纬度,也说明在这段时间内荒漠草原广布于黄土高原。石膏的发育还揭示,在350~280 ka PB前后黄土高原气候发生了性质的转变,第3层古土壤发育中晚期和第4层古土壤发育早期最少各有一个时期气候特别冷干,当时该区已基本不受夏季风的影响,并处于冬季风气候控制的环境下。     

黄土高原南部晚更新世黄土古土壤与气候变迁

本文对黄土高原南部晚更新世黄土地层作了详细划分。根据武功、洛川黄土剖面构地层结构、地球化学和孢粉分析，确定了形成的黄土荒漠草原和平草原寒冷干旱环境，形成的古土壤落叶阔叶林或森林草原温暖湿润环境。阐明晚更新世黄土高原南部有六个土壤、植被和气候演他阶段，并将其归纳为约四万年为周期的三个暖湿—冷干气候变化旋回，与地层剖面上交替出现的三层古土壤与三层黄土相对应。通过与我国东部和北半球各地不同类型古气候记录的对比，证明黄土高原南部晚更新世黄土记录的气候变化规律在北半球具有普遍性。     

新疆第四纪孢粉组合特征及植被演替

本文根据近10年新疆第四纪孢粉工作的主要收获,总结了第四纪地层中出现的主要孢粉类型。阐明了新疆第四纪具有代表性的森林——森林草原、平原河谷林、草原、荒漠草原、荒漠和草甸等六种植被孢粉组合类型。在第四纪,新疆天山南北的主要盆地处于温带干旱,半干旱气候条件控制下,平原植物群以荒漠,荒漠草原和草原为主,并发育低地草原和平原河谷林。阿尔泰山、天山、昆仑山是干旱区中的“湿岛”,植物群以森林、草原、草甸为主。反映了新疆气候演替特点,以温暖期更加干旱而冷期相对湿润的模式,另外也存在冷暖干湿条件的多种组合。同时还对藜科和蒿属花粉在孢粉组合分类上的重要作用进行了讨论,认为在藜科和蒿属占优势的孢粉组合中,以藜科明显占优势的组合应属荒漠,而以蒿属为主或两者相近的组合应归入荒漠草原或草原。     

科尔沁沙地沙漠化的几个问题：以南部地区为例

根据野外调查和室内分析，认为本区土地沙漠化形成时代至少始于早中更新世，其发展模式为非沙漠化环境与沙漠环境之间的正逆交替过程。其生物气候带分别经历过干冷多风的干草原、荒漠草原和温暖湿润或温凉稍湿的森林草原、疏林草原的多次变更。土地沙漠化和生物气候带的这种变化与全球气候波动引起的我国北方生物气候带水平摆动相吻合。因此，该区土地沙漠化的发展趋势将主要取决于当今全球气候波动的发展趋势。     

内蒙古荒漠区红砂(Reaumuria soongorica)种群格局

在内蒙古荒漠区依照红砂的自然分布,按湿润度梯度,从东到西分别在荒漠草原-草原化荒漠过渡区、草原化荒漠、草原化荒漠-典型荒漠过渡区及典型荒漠植被带上选取样地,对红砂(Reaumuria soongorica)种群进行实地调查,根据植株体积划分等级,运用点格局分析法,对红砂种群分布格局进行了研究。结果表明:从荒漠草原向草原化荒漠的过渡区到典型荒漠,随着干旱程度的加剧,红砂种群密度逐渐下降,从稳定增长型种群向成熟或衰退型种群变化,种群格局由聚集分布变为随机分布,聚集的尺度逐渐减少,在典型荒漠种群也出现了均匀分布。红砂种群级别间的空间关联性,具有很强的空间异质性和尺度异质性。随着干旱化和荒漠化程度加剧,红砂种群内部相互有利的生态关系在减弱,到典型荒漠区甚至有种群内部负向(相互排斥)的生态关系出现。荒漠区红砂群落组成简单,在典型荒漠成为纯一的红砂群落,具有特殊性和脆弱性,应重视保护与合理利用。

Deserts and Aeolian Desertification in China: Book review and some thoughts

Desertification is a global phenomenon that affects about two billion people. It occurs in arid zones where the annual precipitation is below 400 mm, partic- ularly in the marginal areas of the world＇s largest deserts. It is a result of water and wind erosion, over- grazing, global warm-ing, improper soil cultivation, and increased pressure ot population growth, and it causes degradation of soil and natural and agricultural vegetation. The direct result is less food for people and livestock, which influences pop- ulation and animal husbandry fluctuations. Despite ef- forts to combat and reduce desertification, the affected areas are annually increasing.

THE MOST PERFECT EXAMPLE OF AN ALIEN ECOLOGY EVER CONSTRUCTED

Much science-fiction literature is based upon the creation and exploration of alternative environments. Stanley G. Weinbaum's short story, “Parasite Planet,”introduces an unusual environment that may be wrong in the light of recent evidence on Venus but still stimulates the geographical imagination.     

Metals and models: Diagenic modelling in freshwater lacustrine sediments

This review aims to distill and synthesize the existing information on the use of models to describe and predict the distribution and movement of metals in lacustrine sediments. As such it examines the causes of metal diagenesis, the origin and form of the equations that govern these phenomena, and the predictability or measurability of the parameters that appear in the models. The paper concludes by highlighting some seminal results from modelling studies, including the determination of the factors controlling the formation of surficial Mn-Fe-enriched zone or layers, the substantial contribution possible from metal reduction to organic matter regeneration, the calculation of mixing-corrected metal input histories to lakes, and the prediction of growth rates and morphologies for both deep-sea and lacustrine ferromanganese nodules.     

Guidelines to Authors

正1.Aims and scope Sciences in Cold and Arid Regions(SCAR)is a bimonthly journal that publishes in English the latest research achievements in processes and the patterns of the Earth surface system in cold and arid regions.Researches in cold regions emphasize particularly on the cold-region-characterized physical,chemical and biological processes and their interactions,and on the response of cryosphere to global change and human activities as well as their effects on environment and the acclimatizable strategies;focus on the objects of glacier,snow,river,lake,sea ice,permafrost and seasonal frozen ground,and periglacial geomorphology,etc.;and think much of cold regions
