国土资源部拟以土地供应控房价

为具体落实七部委《关于做好稳定住房价格工作的意见》，国土资源部将在两方面下功夫：一方面要通过土地调控措施来保证中低价位、中小套型住房的有效供应，另一方面，在抑制商品住房价格上涨过快上，则要在严格执行土地利用总体规划和土地利用计划的前提下，根据房地产市场变化情况，适时调整土地供应结构、供应方式及供应时间。     

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。     

金矿床的热液流体特征研究

通过对中国东部金成矿区域地质特征的分析,根据氢氧同位素及流体包裹体数据特征,表明中国东部金矿床成矿流体主要来自大气降水,其次为变质作用过程释放的水和岩浆分异水;成矿金属组分主要来自太古宙变质岩系。     

彭州市立体农业气候资源的研究(一)降水资源分析

分析了彭州市境内位于不同海拔高度的4个观测站的降水资料，结果表明，彭州市雨量充沛，但降水量的年际变化显著，雨季起、止时间和雨季长、短的年际变化很大，降水的时间分配极不均匀，因为这4个站具有相同的气候背景、，降水量的年、季、月变化呈现基本一致的规律和趋势，但因为海拔高度不同等气候背的差异，4站的降水特点又显著不同。降水量随海拔高度的升高而增加，降水变幅和雨日也阴海拔高度的升高而增加，大降水过程具有明显的局地性，不同海拔高度的旱、涝情况亦有差异，降水的空间分布表现出明显的立体性特征。

建设新农村节地230亩——西华县安营村社会主义新农村试点走笔

在西华县城东关3公里处,有一个漂亮的村庄,一座座红白相间的两层小楼整齐统一,村内道路横竖一条线,排水沟、绿化带、路灯等公用设施应有尽有……这就是省社会主义新农村试点--西华县皮营乡安营村. 皮营乡安营村共有131户,545口人,共有耕地630亩,人均耕地1.6亩,原村庄面积340.6亩,户均宅基地2.6亩.历届村委没有实行村庄规划,每户宅基地面积大小不等,多则2～3亩,少则0.3～0.5亩,村内道路狭窄弯曲,地势低洼,晴天一身土,雨天一身泥.村里部分"能人"纷纷迁往县城居住,造成村内空宅多,安营村成了名副其实的"空心村",在一定程度上影响了经济发展,极大影响了群众的生产生活.     

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.
