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.

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.

Preliminary study on plasma membrane fluidity of Psychrophilic Yeast Rhodotorula sp.NJ298 in low temperature

The ability of cell to modulate the fluidity of plasma membrane was crucial to the survival of microorganism at low temperature. Plasma membrane proteins, fatty acids and carotenoids profiles of Antarctic psychrophilc yeast Rhodotorula sp. NJ298 were investigated at -3 ℃, 0 ℃ and 8 ℃. The results showed that plasma membrane protein content was greater at -3 ℃ than that at 8 ℃, and a unique membrane polypeptide composition with an apparent molecular mass of 94.7 kDa was newly synthesized with SDS-PAGE analysis; GC analysis showed that the main changes of fatty acids were the percentage of unsaturated fatty acids (C18∶ 1 and C18∶ 2) and shorter chain saturated fatty acid (C10∶ 0) increased along with the decrease of the culture temperature from 8 ℃ to -3 ℃; HPLC analysis indicated that astaxanthin was the major functional carotenoids of the plasma membrane, percentage of which increased from 54.6±1.5% at 8 ℃ to 81.9±2.1% at -3 ℃. However the fluidity of plasma membrane which was determined by measuring fluorescence anisotropy was similar at -3 ℃, 0 ℃ and 8 ℃. Hence these changes in plasma membrane's characteristics were involved in the cellular cold-adaptation by which NJ298 could maintain normal plasma membrane fluidity at near-freezing temperature.

Sea ice thickness measurement in spring season in Bothnian Bay using an electromagnetic induction instrument

As an important component of the cryosphere,sea ice is very sensitive to the climate change.The study of the sea ice physics needs accurate sea ice thickness.This paper presents an electromagnetic-induction(EM) technique which can be used to measure the sea ice thickness distribution efficiently,and the successful application in Bothnian Bay.Based on the electromagnetic field theory and the electrical properties of sea ice and seawater,EM technique can detect the distance between the instrument and the ice/water interface accurately,than the sea ice thickness is obtained.Contrastive analysis of the apparent conductivity data obtained by EM and the value of drill-hole at same positions allows a construction of a transformable formula of the apparent conductivity to sea ice thickness.The verification of the sea ice thickness calculated by this formula indicates that EM technique is able to get reliable sea ice thickness with average relative error of only 12%.The statistic of all ice thickness profiles shows that the level ice distribution in Bothnian Bay was 0.4-0.6 m.     

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.
