In order to study the karstological processes within the karst ecological system,the geohazards and degradation of karst landscapes on the karst areas of the Bakony mountains(Hungary),we investigated the abiotic elements of the environment,soil and cover deposits,erosion soil decay;the changes in the quantity and quality of karst waters:contamination at swallow holes,contamination of karst springs;and the biogenic factors:surface vegetation coverage by the corine land cover method,plant-ecological examinations,qualification of surface waters with the help of biological water *** recognized that the increasing human activities during the past few centuries have had significant impact on the investigated landscapes of karst areas because of their spatial *** the scope of our research we concluded that the landscape changes due to natural and human effects can vary strongly on the different karst *** differences can arise from the climatic and geomorphologic situation,the coverlayer's qualities,etc.,but primarily from the different utilization of the investigated karst areas(*** intensity,characteristics and territorial extension of utilization).On the spot investigation we detected traces of new and fast geomorphological processes(gully formation,landslides,collapses,new sinkhole development) and landforms(sinkholes,gullies,swallow holes),which are clear evidences of the effect of climatic changes.

通过文献资料法、归纳比较分析法和数理统计法对第31届里约奥运会田径项目比赛结果进行分析,对金牌的地域分布和洲际实力进行比较。本届奥运会田径项目整体竞赛水平较高;田径项目奖牌榜发生较大变动;当今田坛主要呈现以美国为超级强国,牙买加和肯尼亚等国家为田径强国的"一超多强"的格局;金牌分布的"地域化"特征明显:北美洲优势明显,欧洲和非洲竞争激烈,亚洲和南美洲稳中有升,大洋洲实力滑坡。中国代表队取得2金2银2铜的历史最佳成绩,传统优势项目竞走和女子投掷继续稳定发挥,男子跑跳项目也有明显进步,进入奥运会田径项目前八名的数量也有明显增加,但中长跑项目整体水平一般,期待继续提高。在当今世界田坛竞争格局下,我国需要继续提升传统项目的竞技实力和寻找新的"增金点",做好各项目的人才培养和选拔,形成项目的集团优势,同时对我国中长跑项目给予支持,促进中长跑竞竞赛成绩的提高。

为研究鄂尔多斯盆地长7页岩油勘探开发潜力,基于X射线衍射、场发射扫描电镜氩离子抛光、高压压汞、气体等温吸附等测试结果,与北美地区典型页岩油从地质背景、烃源岩特征、矿物组分和储集空间类型4个方面进行了对比。结果表明,长7页岩油与北美地区典型页岩油处于稳定的沉积环境中,有利于页岩油成藏。长7烃源岩有机质类型和成熟度与北美相似,TOC含量达到2%~18%,甚至高于鹰滩组页岩油,生油潜力大。长7页岩油脆性矿物总量达到69.73%,仅比北美页岩油低1.27%,可压性强。长7页岩油较北美典型页岩油而言,物性较差,孔隙度和渗透率分别为0.5%~2.1%和(0.000 4~0.03)×10^(-3)μm^2。北美典型页岩油微裂缝和有机质孔发育良好,而长7页岩油有机质孔多呈孤立状分布,储集空间以粒间孔、粒内孔和微裂缝为主。可见,长7页岩油与北美地区典型页岩油成藏规律及矿物组分相似,但长7页岩油物性差,储集空间细小,因此在具有较大资源潜力的同时亦具有较高的开发难度。
