固定铝方法成功恢复汤湖温泉热储平衡温度及其研究意义

铝是地热系统中含量低且难以准确测定的元素，在常见的地热系统中总是有两种以上的含铝硅酸盐矿物达到了平衡，因此可以利用固定铝法来弥补铝分析结果不准或铝分析数据缺乏的弊病，本文以江西汤湖为例，探讨了采用WATCH97程序来弥补铝分析结果不准或铝分析数据缺乏的可能性，不仅获得了相应的矿物共生组合，还得到了深部热储的温度。从而将该方法从SOLVEQ程序推广到WATCH程序，并从中低温地热系统推广到低温热泉系统。     

Understanding community forestry: a qualitative meta-study of the concept, the process, and its potential for poverty alleviation in the United States case

This paper provides an assessment of the conceptual basis of community forestry from around the world, based on case studies presented in the literature, mainly over the last decade. More than 400 documents were examined for this comprehensive qualitative meta-study (meta-theory, meta-analysis, meta-method, and meta-synthesis) of community forestry. An overall conclusion is offered regarding the extent to which community forestry can be adapted to foster practices that enhance livelihoods, particularly for poverty populations, in rural United States communities. Special attention is paid to signifiers of community empowerment and reflexivity as well as other elements of success suggested in the literature.

THE POLITICAL ECONOMY OF FOREST POLICY IN MEXICO AND CHILE

Widespread agreement exists on the broad outlines of the concept of sustainable development for developing countries. This calls for a development model capable of meeting basic needs without depleting natural resources at a rate that robs future generations of their use. In this regard, citizen participation is also considered key to legitimise such policy choices. However, there is considerable disagreement over the substance and meaning of the major components of the concept and the relationship between them. This paper argues that positions in policy disputes over the sustainable development of the forest cluster in two distinct approaches: market‐friendly initiatives and grassroots development. Since market economies prevail almost everywhere, the question that is posed concerns the conditions under which the grassroots development approach is included as a significant complement to market‐friendly initiatives. This is a political question, requiring an examination of actors, interests and power resources. The paper thus applies a political economy framework to a paired comparison of Mexico, where grassroots development approaches (community forestry) had notable successes, and Chile, where market‐friendly forest policy crowded out alternatives.     

采空区岩层移动的动态过程与可视化研究

矿山开采引起上覆岩层的移动是一个复杂的动态过程。在岩层的移动和变形过程中岩体具有流变性质，同时岩层的层状组合结构在运动过程中存在时间和空间上的差异。根据流变力学理论和薄板弯曲理论研究了岩层和地表移动的时间、空间过程，推导出考虑时间因数的地表下沉基本公式和获得岩层与地表下沉时间系数的公式。并基于MATLAB软件强大的数学计算和图形功能，开发了相应的模拟地表沉陷动态过程的可视化程序，对某开采煤矿的地表沉陷动态过程进行预测。其预测结果与该矿长期的实际观测资料基本一致，从而为地表沉陷的动态过程预测提供了新的方法。

黄骅坳陷井壁崩落法现代构造应力场测量

简述了井壁崩落椭圆的特征、识别标志及其测量方法,对黄骅坳陷区内32口井的四臂地层倾角测井和地层倾角测井资料应用Stereonet程序对几千组数据进行分析、处理,得出了黄骅坳陷区域现代构造应力场的最大水平主应力优势方向为N70°—80°E,而枣园油田区局部应力场最大水平主应力方向为N50°—60°E,其结果表明黄骅坳陷区域NEE向水平挤压应力场与黄骅坳陷内的北北东—北东东向断裂现代右旋走滑活动相一致,而枣园油田区由于受风化店构造的局部影响,最大水平主应力方向向北发生了20°—30°的偏转,这表明在统一的区域应力场状态下,局部构造应力场受局部构造的控制。
