河南高家庄铝土矿矿床成因及找矿前景分析

河南鲁山县高家庄铝土矿区位于三门峡—鲁山逆冲断裂带的南部,区内构造复杂,自西向东展布有两个大的逆冲断层,飞来峰较多,岩浆活动不太频繁.矿床从沉积相上来看,属于河南成矿区最南端的汝州—宝丰—鲁山矿带,含矿地层为中石炭统本溪组.通过本次地质勘查工作,全区发现并控制铝土矿矿体4条,铝土矿矿体的分布受寒武系张夏组灰岩古地形风化...     

基于无人机遥感的黄河下游河南段河滩地植物群落多样性研究

周期性的农业活动和水沙变化已经显著改变了黄河下游河滩地的植物群落结构,快速、准确地获取河滩地的植物群落多样性信息,可以为黄河流域生态保护和恢复提供参考依据.以位于河南省新乡市原阳县朱贵村南部的黄河下游河滩地的植物群落为研究对象,采用最大似然、人工神经网络、面向对象和随机森林分类方法,利用无人机多光谱遥感影像数据,对河滩...

Analysis of types and changes of village-level economy in rural Gongyi city,Henan Province since 1990

Based on the research on the rural living standard in China in terms of annual net income per capita, we define six types of village-level economy, i.e. ＂to be extremely poor＂, ＂to make a basic living＂, ＂to dress warmly and eat one＇s fill＂, ＂to try to enrich （to disengage poverty）＂, ＂to be well-off＂ and ＂to be affluent＂. The data of average annual net income of all the 292 villages between 1990 and 2004 in rural Gongyi City, Henan Province were collected, verified and classified. By using standard deviation, coefficient of variation and regression analysis, it is found that the Gongyi＇s rural economy has boosted up remarkably from the relative-poverty and absolute-poverty stages in 1990 to the well-off in 2004. However, the absolute differences between villages present a trend of enlargement, while the relative differences fluctuating. On the other hand, spatial analysis of village-level economy shows that most villages with relatively high economic development level were located along national expressway and most villages with absolute-poverty lay in remote mountainous areas in 1990. Since the 1990s, the rapid urbanization and industrialization have had strongly positive effects on rural economic growth. Initial economic foundation, natural resources and traditional techniques also contribute to village economy. From the perspective of geography, villages with location advantages, such as near urban center or industrial parks, have more chances for their economic development and the ＂core-periphery＂ economic structure has been presented in the process of rural development.     

河南省栾川县鱼库沟铅矿床地质特征及找矿远景

通过对区内成矿地质背景及矿床特征的分析,阐述了本区处于华北地台南缘卢氏栾川台缘断褶带内,秦岭纬向系构造带与北东向新华夏系构造带太行山隆起带的交汇复合部位;矿体产于新元古界栾川群煤窑沟组、鱼库沟组的石英岩、二云片岩、白云石大理岩和下古生界陶湾群三岔口组、秋木沟组钙质砾岩、白云质石英大理岩等地层中;该区大地构造位置独特,地质构造复杂,岩浆活动频繁,围岩蚀变强烈、地球化学异常明显,形成了以Pb,Zn,Mo,Ag等为主的丰富的内生金属矿产,充分证明了该区成矿地质条件良好,找矿远景乐观。
