半生

This doctoral dissertation is composed of several parts: At beginning, the frontal structure, the effects of diabatic heating and orography, the dynamics of frontal circulation and the mesoscale systems associated with front are reviewed. Several problems based on the review are brought forward. First, at present, the semigeostrophic frontogenesis theory is the most appropriate basic framework for the general explanation of the frontogenetic process. However, the comparison between semigeostrophic theory and the observation have revealed some inconsistencies. The newly observational facts increase the inconsistencies.

本博士论文主要由如下几部分组成，首先对锋面结构、地形和非绝热加热对锋的影响、锋生环流及锋面附近中尺度系统动力学问题的历史与现状进行了综述，在此基础上提出需要进行研究的若干问题：(1)、半地转锋生理论直到今天仍是解释锋生过程的最合适的理论框架，但是通过与观测事实比较，人们发现半地转理论不能对许多锋面观测特征给出令人满意的回答，新的观测事实使问题更加突出，这就向人们提出：是什么原因导致半地转理论与实际观测的不符？

The ability of cold resistance of almond was analyzed by the formulation of LT50, the investigation of over-wintering, the measurement of water content in dormant period and the analysis of anatomical structure in the annual branches of two introduced varieties. The results showed: the LT50 of Fritz, Nonpareil and CK was -24.88℃,-20.56℃ and -17.15℃, respectively; the index of chilling injury of these varieties was 10%, 45% and 87%, respectively; and the classification of cold resistance was in turn high resisting, moderate resisting and easily shoot-shriveling.

通过对两个引种扁桃扶兹和那普瑞尔1年生枝条的半致死温度(KT50)拟合、越冬调查、休眠期的含水率及其解刨结构的分析，对扁桃的抗寒力进行了研究，结果表明：Fritz、Nonpareil及CK1年生休眠枝的半致死温度(LT50)分别为-24.88℃、-20.56℃和-17.15℃；冻害指数分别为10%、45%和87%，抗冻害评级依次为高抗、中抗、易抽。

From 6860 to 3170 cal.yr BP,semi-desert steppeexpanded,regional montane forest steppe retreated,suggesting a prolonged warm and dryclimate.Between 3170 and 2340 cal.yr BP,regional forest steppe expanded whereassemi-desert steppe retreated,indicating the climate became cool and wet gradually and thehumidity reached the maximum at the end of this stage.During 2340～1600 cal.yr BP,Poaceae steppe dominated whereas wetland meadow expanded and the montane forest stepperetreated,suggesting a cool and wet climate prevailed,wormwood grass steppe prevailed andthe climatic instability increased after 1600 cal.a BEThe climate and environmental reconstructions by pollen were supported by the diatomrecords.A relative high lake level and moister climate prevailed between 8660 and 7230 cal.yr BP as inferred by the dominance of planktonic diatom genera and high planktonic/benthicratio (〉40).low lake level and dry climate sustained during 7230～2330 cal.yr BP assuggested by the low abundance of planktonic diatom and low planktonic/benthic ratio ～20and the lake returned to high level during 2330～930 cal.yr BP as inferred by there-dominance of the planktonic diatom and the high value of palnktonic/benthic ratio.The pollen-based climate reconstruction was also consolidated by the grain size andPediastrum concentration records.

Ugii Nuur湖周围现代孢粉研究表明：松属为空气传播的外来花粉，其含量变化可能指示了远山森林草原发育状况；禾本科具显著低代表性，母体植物建群时含量通常在10％以下：藜科花粉含量可以指示区域气候干旱程度。2、以现代孢粉研究为基础、可靠AMS~(14)C年代为框架，Ugii Nuur孢粉记录高分辨率地重建了蒙古国中部地区过去8660 cal.yr BP以来的植被和气候变化。8660～7800 cal.yr BP研究区植被为禾草草原，湖畔及河谷低地发育苔草草甸，远山发育松属针叶林和森林草原，气候温和略湿润；其中8350～8250 cal.yr BP湿生草甸扩张，旱生植物成分减少，气候凉湿。7800～6860 cal.yr BP旱生成分增加，气候转向暖干。6860～3170 cal.yrBP半荒漠草原扩张，远山森林草原退缩，山地草原和河谷及湖畔湿生草甸退缩，气候持续暖干。3170～2340 cal.yr BP半荒漠草原退缩，远山森林草原扩张，气候转凉变湿，末期湿度条件达最佳。2340～1600 cal.yr BP禾草草原发育，湖畔及河谷低地湿生草甸扩张，远山森林草原略有退缩，气候总体较凉湿。1600 cal.yr BP以来研究区发育禾草-冷蒿草原，气候波动较大。
