我国地理信息产业标准化的分析与对策研究

我国地理信息产业的迅速发展,对标准化工作提出了新的更高要求。本文阐述了标准化工作对地理信息产业发展的支撑作用,回顾了"十一五"期间我国地理信息标准化的工作进展,以地理信息国家标准及其在研项目的构成情况为基础,针对普遍反映的标准化问题,从标准化工作主体和客体(即:标准制定者及标准本身)的组成和变化的视角进行系统分析,结果表明:我国地理信息国家标准的制定主体仍为标准科研及行业事业单位,企业制定标准的较少;现有地理信息国家标准仍以基础通用和数据资源类标准为主,面向产业发展的应用服务类标准仍然缺乏。分析认为:地理信息产业发展各种标准化问题产生的根源在于当前标准化工作机制不适应产业发展的需要。本文在此基础上,提出了适合地理信息产业健康发展的标准化工作机制设想,以及应采取的对策。     

房产专题信息分类与编码分析

房产地理信息分类编码是房产地理信息管理与应用、房产地理信息系统建设中最基本的问题。如果房产地理信息分类编码体系不合理,将增加系统建库工作量,影响房产地理数据库的使用和信息共享,甚至将缩短房产地理数据库的生命周期,造成巨大的损失。因此,建立完善的房产地理信息编码体系,对房产地理信息系统的建设、房产地理信息管理与应用目标的实现至关重要。根据在南京“数字房产”共享网络平台项目需求分析和数据整合实践中对房产管理业务与管理模型的理解,并考虑到城市各部门和城市间信息共享的需求,笔者提出了一种房产行业地理信息分类编码方案,对房产行业地理信息标准的制定工作具有积极意义。

地理信息公共服务平台的用户分类及服务分类

地理信息技术的发展经历了集中式、模块化、组件化的过程,目前正向地理信息的Web服务方向发展。传统的集中式地理信息系统中,功能的分类决定了用户的分类;而在地理信息服务的架构中,用户的分类导致服务的分类及其与用户分类的映射。本文从地理信息服务的架构出发,分析并提出了面向服务的地理信息公共服务的用户群分类与对应的服务分类,为地理信息公共服务平台的构建和地理信息服务资源的有效组织和整合提供理论依据。     

企业地理信息服务内容和框架研究——以“数字烟草”为例

地理信息服务是地理信息发展的新阶段,当前的研究工作主要侧重在模式研究,而对于地理信息服务与企业和商业的具体应用研究目前还不多见。烟草行业是我国财政税收的重要来源,"数字烟草"是烟草企业的信息化的新的战略阶段。地理信息服务进入数字烟草将给烟草企业和相关商业带来革命性的变化。本文结合数字烟草论述企业地理信息服务的具体应用内容,并给出了相关的框架设计和应用实例。     

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.     

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.
