露天采石场边坡稳定性与加固

舟山群岛位于我国南北海运和长江内河航运干线的交汇点，近临上海、宁波等大都市，区域条件独特。区域内岛屿众多，深水港资源集中，渔业、旅游资源丰富，岛内以丘陵山地为主，地少人多。随着国民经济快速发展，船舶修造业建设、劈山造地、围填海涂及各类市政交通建设等日益增多。使舟山放炮开山的露天采石场仍然较多。     

Effect of Ploughing Depth on the Growth and Yield of Heracleum candicans： a Threatened Medicinal Herb and a Less-explored Potential Crop of the Himalayan Region

This paper examines the effect of ploughing depths （A -- 60 cm, B -- 45 cm and C -- 30 cm） on the growth and yield of Heracleum candicans Wall （Apiaceae）, a threatened medicinal herb of the Himalayan region. This less-explored plant is being suggested as a potential crop for the mountain agriculture. The study was carried out in an orchard in Himachal Pradesh, India at 2500 m altitude, for two successive growth years. During the first year, all plants remained in juvenile state; in the second year, nearly 65 % plants produced flowers only under 60cm ploughing depth. Among its morphological traits, plant height, collar diameter and aboveground flesh weight were found to be strongly correlated （P 〈 0.01） with the belowground biomass during the first year （r =0.968, 0.925 and 0.973, respectively） and during the second year （r=0.945, 0.928 and 0.775, respectively）. Increase in the ploughing depth was significantly correlated （P〈0.01） with all growth parameters, including the belowground dry weight, marketable portion of the produce. The belowground biomass （commercial yield; 16.28 Qt/hec） at depth A was about 2.6 and 4.7 times higher than those recorded at depths B and C, respectively. The results clearly justify the importance of deep ploughing and this paper strongly recommends it for economically sustainable cropping.     

断层相关褶皱理论在准噶尔盆地南缘山前带构造研究的应用

利用断层相关褶皱的构造几何分析方法，对准噶尔盆地南缘山前复杂构造带内基于地震剖面进行了构造解析，搭建了中、东段的构造轮廓和构造组合样式，认为东段阜康断裂带主要表现为至地表的推覆逆掩。由于位移量大部分转移至地表，阜康断裂带的前陆部分无喜山期构造带；西段造山带内的挤压往前陆方向传递过程中以前列式不断释放其位移量，造成在纵向上呈现三排主要的断层相关褶皱带。根据正演平衡地质剖面制作技术对山前复杂构造区地震剖面反射波的构造识别进行了模拟与探讨。     

The Role of Aga Khan Rural Support Programme in Rural Development in the Karakorum, Hindu Kush ＆ Himalayan Region： Examples from the Northern Mountainous Belt of Pakistan

Pakistan is predominantly a mountainous country where rural development activities are characterised by inconsistency, politically motivated short-term projects without proper feedback. Since the inception of the country, the top-down approach has been followed, and the same development plans that were formulated for the plain areas have been extended to the mountains without any modification. In doing so, neither the participation of the local communities was cared for, nor the mountain specificities were considered in the planning process. Moreover, the representation of the local inhabitants was improper and contradictory to the facts. This biased approach has been one of the main causes for the failure of development projects carried out by different agencies of the Government. Contrary to the perception of the state authorities, the mountain communities proved to be more open to accept new approaches and demonstrated the capacity and capability of being a dependable development partner. In this paper, a detailed account of the Aga Khan Rural Support Programme （AKRSP） has been presented to assess and evaluate the approach followed by this non-governmental organisation （NGO）, and the response of the local inhabitants as collaborators in the development process. The achievements of the AKRSP from project planning, implementation and monitoring can be adopted as a model for rural development not only in the plains, but also in the mountainous areas of the developing countries in the world.

螺杆钻进技术在煤田地质勘探中的应用

在煤田地质钻探生产中,由于地质因素、钻进方法、操作不当等综合因素,出现钻孔偏斜严重超限或发生复杂的孔内事故无法处理时,采用传统的纠斜方法和造斜手段来处理,不但费工费时,事故处理和纠偏的效果不佳,而且会给后继施工带来更大的安全隐患。利用螺杆定向钻进技术快速纠斜和绕过复杂的事故孔段,顺利完成施工任务,达到设计目的,收到了很好的效果。     

台湾山地的雨影效应及其表现

台湾岛的雨量受台湾山地的雨影效应影响明显,各地各月随着风向的不同,雨量表现出很大的差异。福建沿海一线存在着一个雨量低值区,主要是由于该地带所处的地理位置及地形条件所决定,与台湾山地的雨影效应无关。
