中国西天山南缘盆山构造转换解析

在西天山南缘,天山造山带向塔里木盆地北缘的盆山过渡,是以前陆褶皱冲断构造形式向库车一拜城前陆盆地渐变,表现为一系列褶皱冲断组合的构造样式。根据独库公路南段构造变形分析,可组合成６个部分：库尔干一铁力买提达坂根带褶皱系、南天山南缘逆冲断裂带、前陆逆冲推覆构造带、前陆双冲褶皱构造带、前陆隐伏逆冲前缘构造带、沙雅一轮台前缘叠加变形构造带。前陆盆地的发展可以划分为晚二叠一早三叠世、中三叠世一侏罗纪、白垩一     

新疆西天山艾肯达坂火山机体与成矿

艾肯达坂一带火山机体位于伊犁石炭一二叠纪裂谷阿吾拉勒二叠纪火山岩带东段,在航卫片表现为较明显的环形构造。艾肯达坂火山穹窿构造保留较完整,地层层面和流动构造呈现以次安山岩为中心,向周边倾斜,倾角平缓稳定,大多小于３０℃,火山岩相较完整,集块岩、火山角砾岩、熔岩待发育,火山岩以钙碱性系列为主,形成环境为造山带,时代确定为早二叠世早期。艾肯达坂铜银矿及３个铜矿点均受艾肯达坂火山穹窿的环状断裂和放射断裂及     

连云港西大堤工程后人工海湾内回淤强度的测算分析

本文重点研究了连云港西大堤工程后人工海湾内的回淤状况,得出以下结论：西大堤的封堵使人工海湾内的水动力和泥沙运动产生了明显的变化。但这只是工程后的局部调整,不会造成严重的淤积。由于湾内泥沙供应量的减少,连云港仍将维持冲淤相对平衡的状态。并且,本文以实测资料为依据,对两类主要的回淤预报公式进行了分析评价,证明了这两类公式的合理性和可靠性。     

Applying the Political Geography of Scale: Grassroots Strategies and Environmental Justice

The grassroots environmental movement often protests locally unwanted land uses. Many grassroots groups have, however, expanded their agenda to the scale of environmental justice. Explanations for this scale transformation include historical circumstances, individuals' radicalization through activism, and the growth of environmental justice networks. This case study, grassroots environmentalists' opposition to a proposed electricity transmission line in Monroe County, WV, explores another explanation: appeals for environmental justice are also a strategic response to siting regulatory procedures. With concepts emerging from the political geography of scale, I interpret the Monroe Countians' efforts and show how their strategies link the grassroots scale with that of environmental justice.
