涉及四川盆地二叠系生物礁前人进行过一些专题研究和讨论(张继庆等,1990;吴熙纯等,1990;王生海等,1992;范嘉松等,1996,2002;朱同兴等,1999),但对四川盆地东北部的通江—南江 巴中至达县—宣汉一带的二叠系由于发现生物礁较少尚未进行生物礁的专题研究。到目前为止,该区在露头上所发现的晚二叠世生物礁主要有南江桥亭生物礁、通江铁厂河林场生物礁、宣汉渡口羊古洞生物礁以及开县的红花生物礁,在覆盖区通过对一些钻孔资料的研究,发现了铁山5井、天东10井、板东4井和双15井等生物礁。2002年,我  相似文献

淤泥质潮滩的广泛分布是中国东部海岸的基本特征之一。本文根据近十几年来的调查研究工作，系统总结了中国东部潮滩在沉积结构、沉积构造及沉积序列上的基本特征及其空间变化规律，初步探讨了本区潮滩的造地、养殖和净化三种主要环境功能，以期为中国东部潮滩资源的合理开发利用和环境保护提供科学依据。  相似文献   

Current measurements and spectral analyses in the upper 450 m and deep layers of the northeastern South China Sea   总被引：4，自引：1，他引：3  

袁耀初  赵进平  王惠群  楼如云  陈洪  王康墡 《中国科学D辑(英文版)》2002,45(11):1008-1026

On the basis of the current measurements from the moored Long Ranger ADCP in the upper 450 m layer and the deep current measurements at 2000 and 2300 m from the moored cur-rent meters with the time series data of about 7 months at the mooring station in the northeastern South China Sea, the spectral analyses and calculation have been made. The major results are as follows: (ⅰ) From the progressive vector diagrams of the observed daily currents at the water lev-els from 50 m to 400 m, its temporal variation of velocity rotated counterclockwise in most of the observing time. This agrees basically with the result from the qualitative analysis of the sea surface height data, which was obtained from TOPEX/ERS-2 altimeter data by CCAR. The daily and monthly average velocities are both the largest in November, next in October and minimum in Au-gust. (ⅱ) At the 2000 and 2300 m levels, the daily and monthly average velocities are both the largest in January, next in September and minimum in August. From the seasonal change of cur-rents, the current velocity is the strongest in winter (January-March), next in autumn, and weak in summer. (ⅲ) There exists the variation of tidal current with the change of depth. In the upper layer, the height of diurnal peak is higher than that of semidiurnal peak. However, the semidiurnal peak is higher than the diurnal peak at the levels from 200 m to 400 m. In the layers above 450 m the clockwise component is dominant in their fluctuations. In the layers below 1500 m the diurnal peak is again higher than the semidiurnal peak. (ⅳ) There is the prominent periodic fluctuation of more than two months in the layer from 50 m to 2300 m. The period of this prominent peak is 75 d and its fluctuation is counterclockwise in the upper 450 m layers, and is 68 d and 69 d at the depths of 2000 and 2300 m, respectively, and the counterclockwise component is dominant in their fluctua-tions. (ⅴ) There are the variations of periods fluctuating with the change of depth in the upper 450 m layers. For example, when f＞0, there are the prominent fluctuations of about 22 d and 15 d pe-riods at the 50 and 100 m levels. However, there are no such periods at the layer from 200 m to 400 m, where only the fluctuation of about 13 d period occurs. (ⅵ) There are the fluctuations with periods of more than one month, 23 d and 15 d at the 2000 m and 2300 m levels. (ⅶ) In the layer from 50 m to 2300 m there are the following prominent peaks: ⅰ) the fluctuation in the period range of about 4-8 d, which occurs in the weather process; ⅱ) the fluctuation with inertial period, the fluctuation is clockwise; and ⅲ) the fluctuations with short periods of about 8 h and 6 h. (ⅷ) From the cross spectral estimates between two time series, it is shown that there are significant coherence peaks with the periods of more than two months (T = 68.3 d) and more than one month between the two time series of currents at 2000 m and 2300 m depths, and also those with periods of about half a month (15.5 d), 2 d and so on between two time series of currents at 100 m and 2300 m depths.  相似文献

莫桑比克罗非鱼在降温过程中与呼吸有关的血糖和乳酸含量变化的研究     

林华英  楼宝城 《山东海洋学院学报》1987,17(4):51-57

在海水中养殖的莫桑比克罗非鱼（Vreochromis mossambicus),水温从20℃开始，以1℃／小时速度下降到10℃为终止温度时发现随着温度的逐渐下降，呼吸次数逐渐减少，水温降至14℃以下时，明显地表现出机能的衰竭。本文对与鱼类体温调节有关的血糖和乳酸的含量，在不同的温度梯度下进行了测定。并对以上两种供能物质的变动情况与呼吸机能衰竭的相互关系进行了分析和讨论。  相似文献

CHIMEHERB人工皮在创面愈合过程的病理组织学观察和生物化学分析     

王静凤  楼宝城 《中国海洋大学学报(自然科学版)》1989,(Z3)

作者在研究CHIMEHERB人工皮肤覆盖创面时发现;人工皮肤与创面之间先是一种液面连接,随着创面渗出的减少,出现一种凝胶状的纤维结合蛋白(FN),使人工皮肤牢固地敷贴创面.在愈合过程的不同时期,进行了组织学切片观察和创面物质的生物化学分析.证实:人工皮肤下的纤维结合蛋白与创面上的多种酶聚集,净化了内环境,为上皮细胞生长提供了营养,对烧伤创面起到了良好的保护和促进愈合作用.  相似文献
