台州市椒江区：积极开展预防职务犯罪教育活动     

李建卫  杨黄华 《浙江地质》2008,(10):61-61

为了进一步加强我区国土资源系统的廉政建设,9月17日,椒江区国土资源分局为全体干部职工举办了一次“椒江区国土资源系统预防职务犯罪廉政教育讲座”,邀请台州市人民检察院反贪污贿赂局原局长蒋建敏同志前来上课。本次讲座通过对典型案例的剖析,生动介绍了职务犯罪的概念和种类、基本规律和职务犯罪的预防对策等方面,强调预防职务犯罪的重要意义,并着重阐述国土系统职务犯罪的一般类型、发生的基本环节和原因。同时,  相似文献   

黑河流域水环境演变及其驱动机制研究进展   总被引：10，自引：0，他引：10  

肖生春  肖洪浪 《地球科学进展》2008,23(7):748-755

基于近几十年来诸多学者对西北干旱区典型内陆河流域——黑河流域水环境演变诸方面研究成果,综述了上游山区成水环境、中游绿洲用水环境和下游荒漠天然绿洲水成环境在不同时间尺度上的演变过程及其驱动机制。通过对各种古环境代用指标的对比研究表明：在大尺度上,流域上下游表现出阶段性的一致性水环境演变趋势;在小尺度上,则表现水环境演变的时空异质性。驱动机制方面,在空间上,流域上、中、下游水环境演变的气候变化和人类活动影响驱动作用各有侧重;在时间上,表现为不同尺度上气候变化与流域人类活动耦合作用的驱动机制。  相似文献   

湖北辽瓦店遗址地层记录的环境变迁与人类活动的关系研究   总被引：6，自引：4，他引：2       下载免费PDF全文

用XRF和ICP-AES方法分别测试了湖北辽瓦店遗址地层样品的氧化物含量和地球化学元素含量,恢复了遗址地层中夏代文化层、东周文化层和明清文化层记录的环境变化和人类活动特征。结果表明:1)夏代文化层时期,气候温暖湿润,生态环境良好,人类活动与自然环境和谐度高,有原始的手工业活动记录。2)东周时期气候开始进入干旱期,干旱程度在上东周文化层中部逐渐加深(LOI=6.98%),到了上东周文化层顶部气候进入暖湿期。该层Cu含量的异常高值(0.31mg/g)和出土的青铜器表明本文化层反映了青铜社会的繁荣期,而P含量的高值(22.73mg/g)和动物骨屑则反映了该期人们驯养、捕猎动物的普遍性。3)明清时期的气候趋于干凉,明代文化层中部有短暂暖湿期,后又进入冷干期。清代文化层中下部有暖湿特征,之后重新进入干冷期。该层Ca(均值101.5mg/g),Mg(均值60.27mg/g),Zn和Pb的高含量表明遗址曾有过制陶(瓷)业的历史。另外,Mg和Ca含量的高值与耕作区、墙壁灰浆、生活垃圾堆积等人类活动相关。Ca和Mg含量在近现代层逐步升高揭示了人类活动逐渐增强的事实。地层的平均粒径自上东周文化层(<142cm)开始出现振荡,暗示汉江洪水和季节性山洪发生的频率不断增加,表明恶劣环境条件虽然促进了人类生产力水平的提高,但原始生态系统却遭到破坏,人类活动对自然环境的正反馈效应日益凸显。  相似文献   

新疆南天山库车坳陷区东秋里塔格断褶带构造特征及新活动性   总被引：2，自引：1，他引：1  

陈建波  沈军  向志勇  李军  吴传勇  赵欣  曾宪伟 《新疆地质》2008,26(2):137-141

库车坳陷是南天山中段新构造运动异常强烈的地区,内部发育有四排近EW向展布的逆断裂-背斜带,由南天山山前向塔里木方向依次为:山麓逆断裂-背斜带;喀桑托开逆断裂-背斜带;秋里塔格逆断裂-背斜带和亚肯盲逆断裂-背斜带.东秋里塔格背斜属秋里塔格逆断裂-背斜带东段部分,其构造运动尤为强烈.研究表明:东秋里塔格背斜是浅部滑脱面与其南翼逆冲断层共同形成的断层传播-滑脱混生褶皱,背斜南翼的浅层逆冲断层和深层的断坡构造是重要孕震场所.东秋里塔格浅部背斜核部的背冲式断裂和北翼的膝折属于派生的次级构造,断裂的规模、错动量有限.东秋里塔格背斜南翼逆断层最新活动错断Ⅱ级阶地砾石层,其活动年代至少为全新世早期,这次错动在地表留有3～4 km长的古地震破裂形迹,说明断裂具粘滑运动特征.  相似文献

汞元素的石油地质意义     

李广之  袁子艳  庄原  江浩 《物探与化探》2008,32(2):143-146,185

油气中都含有汞元素组分,汞的物理化学性质决定其可以从油气藏中向上垂向运移,根据采样介质类型及样品预处理的手段不同,地表中汞的分析方法可分为壤气、热释汞及土壤总汞分析方法。壤气汞、热释汞及土壤总汞指标都有着很好的示油气意义,同时也有着示断裂带的地质意义。  相似文献   

The Role of Fracture Structure in Leachate Pollution at Landfills： A Case Study of a Landfill in Chongqing City     

LUO Yunju  LIU Dongyan  LI Xiulan  ZHU Zhengwei 《《地质学报》英文版》2008,82(5)

This paper studies a landfill where there are three faults running through.As serious pollution has occurred to the geological environment,the landfill is to be closed up and renovated.The paper aims to explore the role of fracture structure in leachate pollution at the landfill.The research was carried out in several stages.First,mathematical models of the pre-renovation landfill with three faults running through and the landfill after renovation were established.And then,the boundary conditions and parameters of the two mathematical models were determined.The groundwater level of the landfills was simulated in order to modify the two mathematical models.As a result,a feasible mathematical model was achieved.Based on this model,a comparison was made of the COD concentration variations in the inside leachate and outside leachate between the two landfills. Accordingly,the impacts of the fracture structure on the pollution of leachate at the landfills could be identified.The study results show that while faults contribute to the migration of leachate,they also serve as a confluence of leachate,thus further deteriorating the environment.The COD concentrations of the inside leachate and the outside leacbate of the pre-renovation landfill are respectively 800 mg/L and 220 mg/L higher than those of the post.renovation landfill.Therefore,measures must be taken to handle the leachate seepage in areas where there are faults as well as the neighboring areas so as to get the environmental pollution under control.  相似文献   

The Role of Fracture Structure in Leachate Pollution at Landfills: A Case Study of a Landfill in Chongqing City

This paper studies a landfill where there are three faults running through. As serious pollution has occurred to the geological environment, the landfill is to be closed up and renovated. The paper aims to explore the role of fracture structure in leachate pollution at the landfill. The research was carried out in several stages. First, mathematical models of the pre-renovation landfill with three faults running through and the landfill after renovation were established. And then, the boundary conditions and parameters of the two mathematical models were determined. The groundwater level of the landfills was simulated in order to modify the two mathematical models. As a result, a feasible mathematical model was achieved. Based on this model, a comparison was made of the COD concentration variations in the inside leachate and outside leachate between the two landfills. Accordingly, the impacts of the fracture structure on the pollution of leachate at the landfills could be identified. The study results show that while faults contribute to the migration of ieachate, they also serve as a confluence of leachate, thus further deteriorating the environment. The COD concentrations of the inside leachate and the outside leachate of the pre-renovation landfill are respectively 800 mg/L and 220 mg/L higher than those of the post-renovation landfill. Therefore, measures must be taken to handle the ieachate seepage in areas where there are faults as well as the neighboring areas so as to get the environmental pollution under control.  相似文献
