Research of the Strategy of Local Government Non-coal Mine Safety Production——A Case on L City of F Province

我国是矿产资源大国，矿业经济发达，矿山企业众多，截至2010年底，全国共有非煤矿山75937座。在为经济做出重要贡献的同时，非煤矿山行业的安全生产问题也较为突出，2001年至2013年期间非煤矿山行业平均每年发生事故1400多起，在所有工矿商贸行业中仅次于建筑施工和煤矿。我国安全生产工作实行分级管理和属地管理，所以地方政府及安监部门承担了主要的非煤矿山安全生产监管职责，因此，提高地方政府非煤矿山安全监管能力对于促进非煤矿山行业整体安全生产形势的稳定好转有着重要意义。 对非煤矿山安全生产的监管中涉及众多的利益关联方，如上级的政府及监管部门、地方的政府及监管部门、非煤矿企业及其职工等，各方基于不...China is abundant in mineral resources and mining enterprises. At the end of 2010, there were 75,937 non-coal mines. Dispite their important contribution to the economy, non-coal mine production safety issues also prominent. During 2001 to 2013, non-coal mine accidents occur over 1400 annually in average, only less than that in building construction and coal mine during all mining and commercial. ...学位：管理学硕士院系专业：公共事务学院_公共管理硕士(MPA)学号：X201113601

福建外来船舶压舱水中浮游植物种类组成与丰度及其影响因素的初步研究

2006~2008年间对进入福建沿海4个主要港口的12艘国际航船所携带的压舱水进行浮游植物种类组成和丰度分布的调查.此调查共检测出浮游植物7个门86属239种(含变种和变型),77μm孔径网滤样和20μm孔径网滤样的平均藻类丰度分别为1.2×102cells/dm3(变动在0~9.1×102cells/dm3间)和3.4×103cells/dm3(变动在0~3.0×104cells/dm3间).同时对其中6艘船舶的压舱水样品用f/2培养基培养,共有13种硅藻和1种甲藻被成功培养.文中还分析了压舱水中浮游植物丰度与盐度、水龄的关系,并结合历史资料讨论了压舱水里各类浮游植物的分布

中国东南沿海港口外轮压舱水生物的调查

随机选取东南沿海港口的17艘外来船舶(含8条集装箱船和9条散货船)作为监测对象,进行压舱水浮游植物及动物的物种鉴定和丰度测定,并对监测数据进行统计学分析。检出分属于7个浮游植物门类和5个动物门类的309种外来压舱水生物(包括60种赤潮生物)。外轮压舱水生物的分布及生存状态与水样的水龄和盐度相关。船舶压舱水排放是大家熟知的外来水生生物入侵的主要媒介。本调查结果表明,中国东南沿海外来散货船的压舱水排放所具的潜在生物入侵风险比集装箱船更应受关注
