信息技术在日常地籍管理工作中的应用

地籍是土地管理的基础,准确的土地资料是编制国民经济计划、制定有关政策的重要依据,同时也是落实保护耕地基本国策、实现耕地占补平衡的基础和保障.地籍信息具有种类繁多、数量巨大、时效性强、应用广泛、管理复杂的特点.在信息技术迅猛发展的今天,现代信息技术RS、GPS、GIS和计算机网络技术的应用可以帮助我们全面实现地籍信息采集、处理、存储、传输的网络化和自动化,从而提高了地籍管理规范化水平.

APPLICATION OF GEOGRAPHICAL PARAMETER DATABASE TO ESTABLISHMENT OF UNIT POPULATION DATABASE

Now GIS is turning into a good tool in handling geographical, economical, and population data, so we can obtain more and more information from these data. On the other hand, in some cases, for a calamity, such as hurricane, earthquake, flood, drought etc., or a decision-making, such as setting up a broadcasting transmitter, building a chemical plant etc., we have to evaluate the total population in the region influenced by a calamity or a project. In this paper, a method is put forward to evaluate the population in such special region. Through exploring the correlation of geographical parameters and the distribution of people in the same region by means of quantitative analysis and qualitative analysis, unit population database (1km× 1km) is established. In this way, estimating the number of people in a special region is capable by adding up the population in every grid involved in this region boundary. The geographical parameters are obtained from topographic database and DEM database on the scale of     

切实保障失地农民的长久收益

中央反复强调，没有农民的小康，就没有全国人民的小康：没有农村的现代化，就没有国家的现代化。农民富才能全民富，农业兴才能百业兴，农村安才能天下安。“三农”问题说到底就是土地问题，土地是农民的“命根子”，是农民最可靠的社会保障。国土资源部门作为涉农部门，做好“三农”服务工作，特别是做好失地农民的征地补偿安置和基本生活保障工作，肩负着重要的历史使命。     

Mantle processes during ocean formation：Petrologic records in peridotites from the Alpine－Apennine ophiolites

Mantle peridotites were early exposed at the sea-floor of the Jurassic Tethys derived from the subcontinental mantle of the Europe-Adria system. During continental rifting and oceanic spreading, these lithospheric peri-dotites were percolated via diffuse reactive porous flowby melt fractions produced by near-fractional melting of the upwelling asthenosphere. Ascending melts inter-acted with the lower lithosphere, dissolving pyroxenes and precipitating olivine, and crystallized at shallower levels in the mantle column causing melt impregnation.Subsequent focused porous flow formed replacive dunitechannels, cutting the impregnated oeridotites, which were conduits for upward migration of MORB-type liq-uids. Melt migration produced depletionlrefertilization and significant heating of the percolatedlimpregnated mantle, i.e the thermochemical erosion of the litho-sphere. Impregnated and thermally modified lithos-pheric mantle was cooled by conductive heat loss dur-ing progressive lithosphere thinning and was intrudeaby MORB magmas, which formed Mg-rich and Fe-richgabbroic dykes and bodies. Alpine-Apennine ophiolitic peridotites record the deep-seated migration of melts which changed their compositions and dynamics during the rift evolution. The thermochemical erosion of the lithospheric mantle by the ascending asthenospheric melts, which induces significant compositional and rhe-ological changes in the lower lithosphere, is a major process in the evolution of the continent-ocean transi-tion towards a slow spreading oceanic system.     

The Statistical Analysis of Migration of Strong Earthquakes-Taking the North China Region asan Example

The migration of strong earthquakes is an important research topic because the migration phenomena reflect partly the seismic mechanism and involve the prediction of tendency of seismic activity. Research on migration of strong earthquakes has mostly focused on finding the phenomena. Some attempts on getting regularity were comparatively subjective. This paper suggests that there should be indices of migration in earthquake dataset and the indexes should have statistical meaning if there is regularity in the migration of strong earthquakes. In this study, three derivative attributes of migration, i.e., migration orientation, migration distance and migration time interval, were statistically analyzed. Results in the North China region show that the migration of strong earthquakes has statistical meaning. There is a dominant migration orientation (W by S to E by N), a dominant distance ( ≤ 100kin and on the confines of 300 ～ 700km), and a dominant time interval ( ≤ la and on the confines of 3 - 4a). The results also show that the migration will differ slightly with different magnitude range or earthquake activity phase.

定位服务忙天涯若比邻

据说人类80%的活动都与地理位置相关,由此而产生了许许多多的与“位置”相关的技术与服务,从远古的路标、地图、……,到当今时髦的GIS、导航系统、……,都是每个人日常生活与工作中不可缺少的一部分。与此同时,人类的通讯手段也在不断发展,无线通讯已将“天涯咫尺”变为现实,以至于见到某个人对着电话说“您现在在哪儿,在国内吗?”时,已不会有人觉得奇怪了。得益于人类80%活动的需求和现代通讯技术的发展,定位服务(LocationBasedService,LBS)得以产生并飞速发展。LBS是多学科交叉融合的产物,它将无线通讯技术、互联网技术、空间数据库…
