简介：以资源一号02C卫星数据为遥感数据源,在粤北地区开展了矿山地质环境监测。在野外踏勘建立解译标志的基础上,进行人机交互解译,获取了研究区的矿山地质环境状况,并进行了野外实地验证,同时也对资源一号02C卫星数据在矿山地质环境监测应用中存在的问题和不足进行了分析,并提出了改进方向。研究发现,利用资源一号02C卫星数据能较好的提取矿山土地资源占用、地质灾害、环境污染等地质环境信息和环境治理恢复情况,为矿山环境治理恢复提供有效的技术支撑。

简介：随着电子技术的发展，网络营销对传统的营销方式提出了严峻的挑战。传统的4P组合是否已被网络所抛弃，取而代之的应该是从顾客需求角度来研究的4C组合?笔者认为：网络营销是4P与4C互相的整合，即利用传统营销的推广手段来推广网上的服务，只有这样融合起来才能达到最佳的效益效果。

简介：通过对武汉东西湖区典型第四纪钻孔ZK02孔沉积物的粒度特征分析,重建了武汉东西湖区第四纪以来的沉积环境演变过程。结果显示,该区早更新世时期为河流相的沉积环境;中更新世—晚更新世晚期,为河湖交替相的沉积环境;全新世早期—全新世中期,为开阔的河流相沉积环境;全新世中期以来,整体处于湖泊沼泽相的沉积环境。区域上地层对比还显示该区全新世地层沉积厚达50m,可能是晚更新世晚期全球气温骤降,海平面急剧下降导致汉江水系下切侵蚀后快速堆积形成的,沉积记录显示末次冰盛期该区存在最深海拔达-22m的深切河槽现象。

简介：美国煤层气开发已经从过去局限于煤矿瓦斯防治范畴发展为一个能源工业部门．并列入“气候变化行动计划”。但是由于地质方面的原因．煤层气生产缺乏与天然气生产经济竞争能力．因而需要政府给予扶持政策。本文分析煤层气生产的经济性．介绍美国联邦政府对煤层气项目的财政支持政策．包括提供优惠贷款和税款补贴等．最后提出加快我国煤层气开发的经济政策建议。
