扬子地台西北缘前陆逆冲带及煤田构造特征

扬子地台西北缘前陆逆冲带(即龙门山逆冲带)的形成和演化控制着扬子地台内部及其西北缘煤炭资源的聚积和赋存。它可分为根带、中带、锋带三部分。根带无煤聚积,工业煤炭资源赋存在中带,锋带的煤系埋藏过深。前陆逆冲带内的煤田构造变形是适应前陆逆冲挤压应力作用的结果,以发育有冲断叠瓦扇、双冲构造、平行褶皱、斜歪褶皱、飞来峰、逆冲岩席、断夹块等构造样式为特征。前陆逆冲带的形成是特提斯构造域长期演化、沿三条缝合带发生三次碰撞的结果。

华南海岸沙坝瀉湖型潮汐汊道口门地貌演变

华南海岸沙坝湖型潮汐汊道主要分布在小潮差岬湾海岸段。汊道口门基本地貌单元有口门深槽、落潮三角洲、涨潮三角洲、内弯沙嘴等，其形态特征与海岸动力及泥沙条件有关。汊道口门迁移、落潮主水道迁移、冲流坝和水道边缘坝向岸迁移和并岸，是汊道口门地貌演变的主要模式并具周期性特点。　湖港湾大规模围垦堵海或注入港湾的河流改道直接入海，这些人类活动可能导致汊道口门急剧变化和航行条件恶化而必须进行整治。     

微动线型台阵数据快速处理研究

针对城市微动探测快速实施的需求,开发了一套可视化微动探测数据快速处理软件。该软件主要功能包括微动野外观测报表校核、数据格式转换、微动有效授时数据段挑选、台阵数据截取、台阵参数计算、频散曲线提取及测线显示等,可较大地提高微动线型台阵观测及数据处理速度。沿着本文思路,可同样进行三角形台阵滚动观测数据的快速处理。

Effects of probiotic on microfloral structure of live feed used in larval breeding of turbot Scophthalmus maximus

The effects of an exogenous probiotic( Bacillus amyloliquefaciens) on microbial community structure of B ranchionus plicatils and A rtemia sinica were evaluated in this study during turbot( Scophthalmus maximus) larval breeding. The analysis and comparison of the microfloral composition of live feed with probiotic was conducted using the Illumina HiSeq PE250. The abundance of microbial species and diversity of microflora in live feed with B. amyloliquefaciens were higher than those in the control. The microfloral composition was similar among the three replicate experimental groups of B. plicatils compared with the control after enrichment. L actococcus, Pseudoalteromonas, and Alteromonas were always dominant. Additionally, some other bacterial species became dominant during the enrichment process. The microbial community during nutrient enrichment of A. sinica was rather similar among the three control replicates. Relative abundance of Cobetia sp., the most dominant species, was 54%–65.2%. Similarity in the microbial community was still high after adding B. amyloliquefaciens. Furthermore, P seudoalteromonas and Alteromonas replaced Cobetia as the dominant species, and the abundance of Cobetia decreased to 4.3%–25.3%. Mean common ratios at the operational taxonomic unit level were 50%–60% between the two B. plicatils and A. sinica treatments. Therefore, the microbial community structure changed after adding B. amyloliquefaciens during nutrient enrichment of B. plicatils or A. sinica and tended to stabilize. Additionally, the abundance of V ibrio in any kind of live feed was not significantly dif ferent from that in the control. These results will help improve the microflora of B. plicatils and A. sinica and can be used to understand the multiple-level transfer role of probiotic species among probiotic products, microflora of live feed, and fish larvae.
