新型土地利用变更与管理软件开发与应用 总被引:2,自引:0,他引:2
通过分析当前土地利用变更调查工作的现状及现实要求。总结了新一轮土地利用变更调查对土地利用变更与管理软件的基本要求,提出了基于SuperlMap的土地利用变更与管理信息系统的解决方案。并就基于SuperMap的土地利用变更调查与管理信息系统的开发与应用进行了详尽的论述。该解决方案成功地应用于柳州市土地利用数据库建设及土地利用数据更新与管理。该系统的成功应用为新一轮土地变更大调查提供了全面技术和软件解决方案,为国土资源行业土地利用更新调查工作提供了成功的应用案例。 相似文献

正自全国第二次土地调查以来,年度土地变更调查工作在政策和技术上不断有新变化和新要求,按照新机制、采用新方法开展年度土地变更调查已进入常态。本年度漳浦县土地变更调查存在遥感监测成果下发时间晚、部分遥感监测影像分辨率低、遥感监测图斑量大等困难因素。利用奥维互动地图进行外业调查,能够高效率、高质量地完成调查工作,为整体土地变更调查工作争取宝贵的时间。 相似文献

GPS在县(市)级土地调查变更中的应用研究 总被引:1,自引:0,他引:1
一、GPS技术应用于县(市)级土地变更调查的意义
土地调查成果是制定各级国民经济计划和宏观决策的重要基础资料,是实施土地利用总体规划和日常土地管理工作及各级领导进行科学决策的依据。决策的科学性,取决于国土资源各项数据的准确性、现实性。因此新一轮土地变更调查测绘成果要能满足对土地利用数据进行及时更新和汇总。数字国土工程的实施,使全国各地陆续建立了县级利用数据库。[第一段] 相似文献

土地利用变更调查是土地管理中最基础、最重要的环节.做好土地利用变更调查工作,准确反映城乡土地利用现状,是严格执行土地管理法律、法规,实施新一轮土地利用总体规划编制的需要,是保护和合理利用土地,建立良好的土地市场秩序,深化土地产权制度改革的必然要求,是政府进行城乡经济社会发展宏观决策的重要基础和依据.土地利用数据变更是土地变更调查的重要工作之一,变更过程中需要处理大量数据,因此提高土地利用数据变更的效率和准确性,成为亟待解决的问题. 相似文献

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. 相似文献

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. 相似文献

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. 相似文献
