市地级短期气候预测业务系统

利用目前9210通信卫星网络中所获得的气象资料,实现大气环流场资料的自动处理和追加,并在MI-CAPS平台上进行二次开发,按月、旬、候的方式处理成Micaps系统的4类数据格式,分类存放.建立了本地短期气候预测业务平台.系统由资料库系统、短期气候预测系统、实时监测决策服务系统3个子系统组成.     

中扬子海盆古-中生代之交沉积环境变化规律及动力学特征

从随机动力系统角度,在厘米级的岩性变化尺度上,定量分析了鄂东二叠系大隆组顶部和三叠系大冶组底部的沉积行为及动力学特征.多种统计学方法研究表明:二叠系大隆组顶部的沉积过程为稳定的Markov过程,地层相关性弱,岩性变化处于随机状态;三叠系大冶组底部的沉积过程为非稳定的Markov过程,地层相关性渐强,岩性变化处于有序状态.在沉积旋回的跃迁方式上,前者表现为混沌,后者则具有周期特征.两者的沉积过程虽连续,动力学性质却截然不同.故古-中生代之交的这一沉积界线也是一个动力学意义上的突变界线,是地质环境经连续变化达到临界状态后发生突变的一种沉积响应.

BIOCHEMICAL CHANGES DURING DEVELOPMENT OF EGGS AND YOLK-SAC LARVAE OF HERRING AND PLAICE

Changes in quantities of water, sodium, potassium, lipid and protein were compared in developing eggs and yolk-sac larvae of herring dupes harengus L., a species with demersal eggs, and plaice Pleuroncctcs platessa L., a species with pelagic eggs. The principal difference between the two species was the occurrence in herring, but not in plaice of considerable increases in water content and in one or both of the above ions at three distinct stages: at fertilization,during the middle stage of egg development, and in the days immediately after hatching. Newly hatched larvae of the two species differed greatly in water content because of the difference in mass and water content of the yolk, not in the water content of the rest of the body. In herring, there were increases in sodium and potassium which coincided broadly with the increase in water content. These differences are related to the gradual acquisition of buoyancy by herring during this period, comparable with the buoyancy conferred on plaice eggs a     

A candidate of the Induan-Olenekian boundary stratotype in the Tethyan region

The Olenekian Stage was proposed by Kiparisova and Popov[1] based on the type section along the lower reaches of the Olenek River, Siberia. Later research showed that this section con-tains only the Olenikites spiniplicatus Zone of the Upper Olenekian Sta…     

陇西民和黄土CaCO3和有机碳总量的含量变化及其气候指标的局限性

民和黄土地处黄土高原与青藏高原东北缘的交接部位,对气候反应较敏感,对该黄土1.87-0.70Ma BP段进行了CaCO3和有机碳总量（TOC）的采样分析。民和黄土CoCO3含量在5.89%-18.63%之间变化,平均11.41%;有机碳含量较低,在0.007%-0.452%之间,平均0.088%。民和黄土中的CaCO3含量明显高于兰州、洛川和西安等地,而有机碳含量则远低于上述地区。黄土中CaCO3和有机碳含量变化反映了该区1.87Ma BP以来气候变干冷的趋向。分别受复杂的CaCO3来源与类型、困难的采样、地区上的差异对比等和有机碳保存条件、沉积速率以及“埋藏效应”的影响,黄土中的CaCO3和有机碳的波动变化作为气候变化的替代性指标存在一定的局限性。文章最后指出,在实际应用中,黄土（特别是黄土高原西北部）中CaCO3和有机碳气候指标应结合其他环境指标共同使用,才能从中提取正确的古气候信息。
