土地综合整治难点何在？——溆浦新坪项目调查

开展土地综合整治，实施“万村土地综合整治”示范工程，是今年国土资源部推出的一项重大行动。大力推进土地综合整治可增加有效耕地面积，改善农业生产条件和农村生活环境，促进土地节约集约利用，也是保发展、保红线的结合点，统筹城乡发展的新平台，当前还能有效地拉动农村投资和消费需求。溆浦县桥江镇新坪村是怀化土地综合整治的首个试点村，近来就该村实施情况进行了调查。     

The Geologic Time Scale and the Italian stratigraphic record

The construction of the Geologic Time Scale (GTS) is a titanic scientific challenge that has been under way for two centuries and will require much dedicated effort in the future. Italy preserves a paramount stratigraphic record of Mesozoic and Cenozoic marine sediments that have been significant in the development of the modern GTS. The Italian stratigraphic record has been histori-cally important in introducing and defining the standard Chronostratigraphic Units (CUs) of the Neogene and Quaternary. Pelagic successions from Northern Apen-nines and Southern Alps have been used in the seventies for integrating the late Cretaceous-Paleogene Geomag-netic Polarity Time Scale (GPTS) with planktonic microfossil biostratieraohv and standard CUs. This was a major contribution to the construction of a new gener-ation of GTS based on integrated magnetobiochronol-ogy. The middle Miocene to early Pleistocene marinerecord from Sicily and southern Italy has been funda-mental for establishing the recently developed Astro-nomical Time Scale (ATS). In prospect, there are many potentials still to be exploited in the Italian marine stratigraphic record for implementing the GTS by defin-ing GSSPs of various CUs, improving magneto-biochronology and extending downwards the ATS.     

Sedimentary characteristics of tide-dominated estuary in Donghetang Formation（Upper Devonian）, central Tarim Basin

The Donghetang Formation （Upper Devonian） in central Tarim Basin has been thought an important oil and gas reservoir since the abundant oil and gas resources were found in the wells W16, W20, W34, and other fields. However, the sedimentary environment of the Donghetang Formation has been disputed because it suffered from both tidal and fluvial actions and there were not rich fossils in the sandstone. After the authors analyzed sedimentary features by means of drill cores, well logging data, paleosols, and with SEM obseruations, three kinds of sedimentary environments were distinguished： alluvial fan, tide-dominated estuary, and shelf. Particularly, the sedimentary features of tide-dominated estuary were studied in detail. Besides, the authors discussed sedimentary characteristics of the Donghetang Formation which was divided into two fourth-order sequences and five system tracts. At the same time, according to the forming process of five system tracts, the whole vertical evolution and lateral transition of tide-dominated estuary were illustrated clearly. Finally, the reservoir quality was evaluated based on porosity and permeability.

提高政府应急处置能力

突发公共事件涉及领域、部门多,形成统一协同的应急机制与能力是当今各国公共安全领域追求的目标。通常提到的应急联动系统、应急指挥平台和应急信息系统等,反应了对应急管理范围和深度等认识的变化。专家指出,应急平台由基础支撑系统和综合应用系统两大部分组成,其核心功能由信息获取系统、应急智能系统和决策指挥系统三个部分组成。消除应急过程中政府部门和业务部门以及各种社会力量之间的不和谐因素,是应急工作的一个重要方向。     

信息化测绘的本质是服务

在世界高新技术飞速发展和社会需求不断变化的推动下,国际上测绘的发展正在经历一场以地图生产为主转向以地理信息综合服务为主的重大变革。我国测绘目前已实现了生产技术层面的转变,正面临着进入地理信息服务阵地的重大变革。     

推行内部土地使用证 加强铁路用地管理

铁路是国家的重要基础设施,是国民经济的重要基础产业部门,是国民经济的大动脉,在国家综合交通体系中起着重要的骨干作用。而铁路用地,是铁路运输生产的重要基础,是维护铁路运输安全的重要条件,是铁路经营的重要资产,是铁路改革发展的重要资本。铁路用地资产量庞大等特点,决定了铁路用地管理工作是铁路改革发展的重要组成部分,因此,加强铁路用地管理,推行铁路局内部土地使用证,是有效发挥土地管理为铁路改革和发展提供保障和服务的有益探索。     

我国位居资源绩效最差国家行列

中国科学院28日发布的（2006中国可持续发展战略报告》首次提出了综合评价节约型社会的节约指数，并对世界59个主要国家的资源绩效水平进行了排序，结果表明丹麦是资源绩效最好的国家，中国仅排在第54位。
