对现行《土地管理法》一些问题的研究

现行土地管理法主要内容和优势 一、现行土地管理法的主要内容的研究 1998年修订的新<土地管理法>主要内容包括:(1)保护耕地.保护耕地是我国土地管理法的核心内容,包括:确立了耕地总量动态平衡制度,明确了省级政府保护耕地的责任;确立了耕地占补平衡制度;将基本农田保护制度上升为法律,规定国家实行基本农田保护制度;加强了对建设用地总量和城市建设用地规模的控制,规定下级土地利用总体规划中的建设用地总量不得超过上级土地利用总体规划确定的控制指标;城市建设用地规模应当符合国家规定的标准等.     

中国将设立国有土地收益基金

据透露．2005年政府将要设立国有土地收益基金。近年来．由于许多地方政府，片面追求政绩工程，到处圈地占地以地生财，把70年的土地收益用于本届政府土地开发和城市建设，导致许多中等城市，特别是东部城市现在已经没有地可卖．这样直接影响到了下届政府的土地收益，为此国家准备从今年开始设立国有土地建设资金，也就是将卖地收益纳入基金，为以后政府的使用做准备。

长乐-南澳剪切带晋江段构造岩特征及其构造变形机制

长乐-南澳左行韧性剪切带位于东南沿海，是酉太平洋大陆边缘构造带的一个组成部分。本文基于野外观察及室内分析，并借助透射电镜对变形石英的内部结构进行了观察，利用变形石英显微构造参数估算剪切带中的应力差值，由此探讨了形成构造岩的机制。     

安徽：整改不到位不恢复农转非审批

近日，安徽省国土资源厅就恢复农用地转用和征地审批有关问题发出通知。通知强调，凡是在治理整顿期间违反土地集中统一管理规定、国土资源部和省政府批办违法案件未上报处理结果和存在问题整改不到位的市、县，将暂停恢复农用地转用和征地的审批。恢复农用地转用和征地审批后，各地要严格按照国家和省有关法律法规和国务院《决定》、《安徽省人民政府关于深化改革严格土地管理有关问题的通知》及《安徽省国土资源厅、安徽省发展和改革委员会关于下达2005年全省土地利用计划的通知》要求，     

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.
