城镇基准地价评估成果管理信息系统

目前,各城镇一般选择AutoCAD和Excel对基准地价评估成果图和成果表分别管理,这种管理主要问题表现为:数据更新效率低;图与表数据不一致性;数据分析和图表双向查询困难;结果输出形式单一等.系统改用MapInfo系统软件基础平台,建立评估成果空间数据库,利用组件开发方式,建立基准地价评估成果管理信息系统.该系统通过文档管理、成果图表管理和GIS专题子系统集评估成果图、表、文于一体,实现了对成果信息的图形操作、属性管理、信息查询、空间分析和专题制图等,保证了地价评估成果图、表数据显示和更新的一致性,图件编制、数据维护和信息分析更加直观、简单,改善了原有基准地价评估成果管理现状,提高了基准地价评估成果管理水平.

加强基准地价评估更新工作——加强浙江省地价管理问题调研报告

为贯彻国务院和浙江省政府关于加强地价管理的要求,近期我们就全省基准地价更新、评估工作及地价管理情况进行了调研。 (一)城镇基准地价评估、更新的基本情况 浙江省城镇基准地价评估工作始于1990年,是全国最早开展基准地价评估的省份之一。杭州、温州和宁波三个城市都是原国家土地管理     

基于GIS的地价审核监测系统研究和应用

一、地价管理的重要意义 地价,即土地价格,是土地所有者权益的体现,是土地管理的一个基础信息.我国城镇国有土地使用制度改革的核心在于土地有偿使用,而有偿使用的前提在于引入了地租地价理论,使土地资产有了地价这个量的尺度和标准,并能在市场上得以实现.近20年来,国家建立起了地价评估制度,制定了一系列地价政策和地价管理措施,为全面推进国有土地使用制度改革,建立和规范土地市场发挥了积极作用,同时通过地价管理带动了国有土地有偿使用中的有关配套工作,有效地促进了土地资源的优化配置,调控了土地供求关系,保障了不同权利主体问的土地收益分配,同时也科学显化了土地资产,为实现土地资产管理提供了基础.     

基于基准地价修订的太原市市区城市地价指数的编制研究

Thermohaline structure inhomogeneity associated with polynia at the northern margin of Emery Ice-shelf

Based on the hydrographic data in austral summer during the 22nd Antarctic Expedition of China(2005/2006),some features can be found about the northern margin of Emery ice shelf as follows.The heat content in the surface layer(0-50 m) at the eastern end and the western end of the ice-shelf margin is much higher than that at the middle.The upper mixing-layer depth and the seasonal thermocline depth at the middle of the ice-shelf northern margin are much shallower than those at the both ends.However there is much less difference between the middle and the ends in the bottom layer.The remote sensing photos show that the inhomogeneity in the surface-layer water is closely related to the spatial distribution of the floes and polynia in the area.     

Phylogenetic analysis of cultivable bacteria isolated from Arctic sea-ice

Phylogenetic analysis based on 16S rDNA of 8 strains of cultivable bacteria isolated from Arctic sea-ice was studied.The results showed that strain BJ1 belonged to genus Planococcus,which was a genus of low mole percent G C gram-positive bacteria;strain BJ6 belonged to genus Burkholderia of β-proteobacteria and the rest 6 strain all belonged to γ-proteobacteria,of which strain BJ8 was a species of Pseudoalteromonas,strain BJ2-BJ5 and BJ7 were members of genus Psychrobacter.Phylogenetic analysis also indicated that bacteria of genus Psychrobacter of the isolates formed a relatively independent phylogenetic cluster in comparison with other bacteria belonged to genus Psychrobacter.

Relationship of Arctic sea ice and Northern Hemispheric 500 hPa Polar vortices

Using the NCEP/NCAR reanalysis monthly 500 hPa height data on a 2.5 latitude-longitude grid and 1°×1° sea ice data,the polar vortex area,intensity index and arctic sea ice area index are calculated respectively,and the meridional distribution,period variation and the abrupts in the long range trend are analyzed to study their relationship.The results show that the meridional distribution of sea ice and polar vortex h-ave distinctive difference,the relative positions of them are different in the eastern and western hemispheres,and exept they have periods of 4 months,quasi half year,quasi year,4-5 years and 10 years commonly,and each of them has its own respective variation as well.The sea ice area is decreasing apparently since 1980's,so is the polar vortex area,but their abrupt changge time are different totally.The area of sea ice and polar vortex has prominent positive correlation,but the relationship of sea ice intensity,polar vortex intensity,polar vortex area is complicated.
