On Educational System of Lianghuai Salt Area in early and middle period of Qing Dynasty

关于清代盐业史、教育史研究的各类学术著作和论文可谓汗牛充栋，但作为两者交叉部分的盐区教育制度迄今尚无系统研究成果。因此，本论文选择具有典型意义的两淮盐区教育制度作为探讨对象，希望能够窥测到盐区教育基本特征与历史影响。“两淮”地区泛指淮河南北的广大地区，本文专指淮河入海处的海盐产区，尤其限指两淮盐区的盐务中枢——扬州和各个盐场，该区域大部分地方人口密集，又具有河川、湖泊与运河的系统，从而使其具有了发展盐业经济的得天独厚的条件。因此，两淮盐区从唐宋以来，盐业经济的规模和效益一直独占鳌头，对政治、文化产生了深远影响，而扬州这座因盐业而兴的城市亦使两淮盐区成为中国学术文化的中心，从而在经济、文化上为教...The compositions and papers on history of salt industry and edcation is an immense number of books in Early and Middle period of Qing Dynasty. But the salt area educational system which is as a crossover part of them, there are still few ones which were systematically researched about it up to now. So in this paper, I select the salt area of lianghuai which has representative signification, as inv...学位：历史学硕士院系专业：人文学院历史学系_中国古代史学号：20030202

明清时期河东书院园林模式思想探议

以明清时代的河东书院为例,探讨中国古代书院园林建筑模式及其所蕴涵的设计思想与教育之间的相互关系,指出书院作为中国古代教育的主要场所,不仅在建筑特点上体现了天人合一、尚中等儒家哲思,更强调了“以人为本,寓教于景”的教育理念和教育境界,将儒家伦理秩序、“忠顺”与“比德”观念和知行合一的践行思想都融入其中,在中国教育史上具有重要意义

风雨淮河：一位工程师的生命史研究

淮河治理是新中国推动实施的第一项大规模水利事业，学术界对于淮河与治淮的研究多集中于灾害、生态与水利工程建设的层面，缺少对于作为一项社会运动的治淮工程之实施过程的细致梳理，更为缺少的是对于参与治淮者个体的关注。本文以治淮工程师郑世莘的曲折人生为视角，考察伴随新中国艰难历程走来的治淮人的命运，并从中观察治淮工程理念的历史变迁，或可对于今天科学地治理淮河、促进淮河流域文明的良性发展提供一定的参考，同时，我们还将深入探究那个时代不间断地出现的政治运动与治淮工程的纠葛，展现一位身处其中的知识分子的生命历程与家国情怀。文部科学省グローバルCOEプログラム 関西大学文化交渉学教育研究拠点［研究ノート・書評

Succession of phytoplankton community in exalted shrimp ponds during culture process

通过对湛江东海岛北寮村和庵里村各2个高位虾池养殖过程的浮游植物演替和主要理化因子进行调查,研究浮游植物群落的演替过程对高位虾池的健康养殖的影响。结果表明:4池共检出浮游植物7门76属140种;对虾生长正常的北寮高位虾池演替优势种主要有螺旋环沟藻、椭圆扁胞藻、海链藻、湖泊束球藻密胞变种、裸甲藻、卵囊藻、微囊藻、锥形斯克里普藻、色球藻和尖尾蓝隐藻等,而对虾发病的庵里高位虾池演替优势种主要有铜绿微囊藻、柔弱布纹藻、咖啡形双眉藻、小席藻、卷曲鱼腥藻、水生集胞藻、衣藻、尖尾蓝隐藻和螺旋环沟藻等,北寮正常虾池浮游植物种类(包括优势种)较对虾发病的庵里虾池多而复杂;对虾生长正常池优势种的演替快而门类交替,而对虾发病池呈现硅藻到蓝藻优势的演替;对虾生长正常池浮游植物密度随养殖过程延伸呈上升态势,而对虾发病池浮游植物密度初期增加病害后下降;养殖过程浮游植物密度与主要理化因子的相关关系不显著;对虾生长正常的北寮高位池多样性指数与均匀度高于对虾发病的庵里高位池,而优势度却较低。水体理化因子变化平缓,浮游植物有较高的多样性指数和均匀度、较低的优势度对于稳定虾池养殖水环境有重要作用。An investigation was made on the succession of phytoplankton community and the main physical and chemical factors of water body in exalted shrimp ponds in Beiliao and Anli villages of Donghai Island,Zhanjiang during culture process,with the influence of the succession on the culture process analyzed.A total of 140 species of phytoplankton belonging to 76 genera and 7 phyla were identified.The dominant species in the two ponds with normal shrimp growth in Beiliao village were Gyrodinium spirale,Platymonas elliptica,Thalassiosira sp.2,Gomphosphaeria lacustris var.compacta,Gymnodinium sp.1,Oocystis sp.,Microcystis sp.,Scrippsiella trochoidea,Chroococcus sp.,and Chroomonas acuta,while those in the two ponds with shrimp disease occurrence in the process of culture in Anli village were Microcystis aeruginosa,Gyrosigma tenuissimum,Amphora coffeaeformis,Phormidium tenue,Anabaena circinlis,Synechocydtis aquetilis,Chlamydomonas sp.2,Chroomonas acuta,and Gyrodinium spirale.The phytoplankton species,including dominant ones,were more abundant and complex in normal ponds than in disease-affected ponds.In normal ponds,the dominant species succeeded rapidly and alternated in phyla,while in disease-affected ponds,only Bacillariophyta species were replaced by Cyanophyta species during the succession.The phytoplankton cell density increased during the culture process in normal ponds,but decreased after a temporary increase at early culture stage in disease-affected ponds.No significant relationships were observed between the phytoplankton cell density and the main physical and chemical factors in the ponds during culture process.The diversity and evenness of phytoplankton species were higher in the normal ponds in Beiliao than in the disease-affected ponds in Anli,while the dominance degree of species was in reverse.The mild variability of water body's physical and chemical factors as well as the high diversity and evenness but low dominance degree of phytoplankton species played important roles in keeping aquatic environment steady and healthy during the culture process in exalted shrimp pond.广东省自主创新重大科技资助项目(2007A032600004
