物权法对节约集约利用土地的法理解析——以青岛市崂山区分层出让建设用地使用权为例

土地资源具有稀缺性和不可再生性,土地供给日渐紧张,拓展土地利用空间、将土地利用由平面趋向立体化发展的趋势日渐成熟。青岛市崂山区将建设用地使用权分层出让,不但垂范了法规政策,对区域经济的发展也具有很大的现实意义。

渤海湾盆地埕岛油田缝洞型潜山油气藏构造及储层特征

埕岛油田古潜山油气藏为典型的缝洞型碳酸盐岩油气藏。埕岛地区经历了多期次的构造运动,并经受了多期次的断裂与剥蚀作用,为油气成藏创造了良好条件。埕岛油田古潜山可以划分为三个构造单元,即埕北20断层下降盘的西排山,上升盘的中排山和东排山,三个潜山带成帚状敛于凸起最南端,为几个二级构造单元交汇处,构造应力较发育。埕岛油田有三种储集空间类型:晶间孔隙、溶蚀孔洞和裂缝。     

鄂尔多斯盆地靖边气田马五_(1+2)气藏储集单元研究

综合地震、地质、测井等信息,考虑沉积、成岩、地貌、生产动态等多因素,在沟槽识别和致密带研究基础上,通过井间干扰、油层压力变化和试井边界响应分析,按照局部、就近原则对靖边气田马五1+2气藏进行了储集单元划分。共划分出111个储集单元,其中独立型69个,复合型42个。这些储集单元的面积多介于10～50km2之间,单个储集单元的井数一般少于6口。在对气藏储层特征综合认识的基础上,确定流动单元划分思路与流程,并认为关键环节包括古沟槽识别、致密带研究、动静结合确定储集单元等3个方面。储集单元一方面受控于被致密岩相包围的有利成岩相带,宏观上与弱—中等充填泥粉晶白云岩相对应性好;另一方面又受各级古沟槽夹持,在两个一级古沟槽之间往往共生多个储集单元,而这些储集单元边界又严格地受二级或三级沟槽切割控制。     

The concentration and distribution of different mercury species in the water columns and sediment of Aha Lake

In order to find out whether Aha Lake was polluted by the acid mining waste water or not, the concentration and distribution of different mercuryspecies in the water columns and sediment profile collected from Aha Lake were investigated. It was found that discernible seasonal variation of different mercury species in water body were obtained in the Aha Reservoir. With regards to the whole sampling periods, the concentrations of HgP in the Aha Reservoir water body were evidently correlated to the concentrations of total mercury, showing that total mercury was mostly associated with particle mercury. The concentrations of methylmercury in water body were also evidently correlated to the concentrations of dissolved mercury. The dissolved mercury evidently affects the distribution and transportation of methylmercury. However, there is no correlation between methylmercury and total mercury. The dissolved mercury, reactive mercury, dissolved methylmercury levels in the water body of high flow period were much higher than those in low flow period. The distribution, speciation and levels of mercury within the Aha Reservoir water body were governed by several factors, such as the output of river, the release of sediment . Discernible seasonal variation of total mercury and methylmercury in porewater was described during the sampling periods, with the concentrations in high flow period generally higher than those in low flow period. The methylmercury in pore water column was evidently correlated to that of the sediment. The results indicated that highly elevated MeHgD concentrations in the porewater were produced at the depths from 2 to 5 cm in the sediment profile, and decreased sharply with depth. A positive correlation has been found between MeHgD formation and sulfate reducing bacterial activity. These highly elevated concentrations of MeHgD at the intersurface between waters and sediments suggest a favorable methylation condition. Moreover,

滑坡及危岩(崩塌)防治工程措施选择与工程设置

滑坡和危岩（崩塌）治理工程措施较多，措施组合可变性大，每种工程措施都有其相应的应用条件，不宜性、适宜性和最佳配置组合。治理工程措施选择应充分考虑治理工程功能性的具体要求、在不同工况条件下的安全性及耐久性、工期要求和投资的经济性以及后期维护的要求、工程岩土体性质及其蓄水后的变化、场地条件、施工技术条件、地方材料资源等具体制约因素以及环境保护的要求。在三峡水库区二期地质灾害防治工程国家级验收总结的基础上，对滑坡与危岩（崩塌）常用防治工程措施（排水、削方减载、回填压脚、抗滑桩、重力式抗滑挡墙、预应力锚索、格构锚固、拦石墙等）的工程适用条件、工程设置及不宜性进行了详细的分析，并提出工程设置应考虑及注意的问题。
