三峡水库自 2 0 0 3年蓄水后 ,水对斜坡 (滑坡 )的软化作用和库岸再造大大改变了库区的工程地质条件 ,库区的地质灾害严重制约了库区移民迁镇工程 ,场地建筑安全评价显得尤为重要。笔者根据库区工程地质的特点 ,提出了场地建筑适宜性评价的指标体系 ,建立了场地建筑安全评价人工神经网络模型。通过对红石包滑坡进行各种工况下的稳定性评价 ,利用稳态坡形、坡角工程地质类比法对红石包进行库岸再造的预测 ,对三峡库区巴东县新城区红石包油库建筑进行安全评价。为库区移民迁镇工作提供科学依据。  相似文献

Community knowledge exchanges have played a key role in developmental processes in the Suid Bokkeveld community of South Africa. Two exchange visits were undertaken with the support of the Department of Agriculture and an NGO, the Environmental Monitoring Group, which have led to local economic development and enhanced capacity to manage natural resources in a sustainable manner. These pilot projects were undertaken within the framework of the Community Exchange and Training Programme of the Global Mechanism of the United Nations Convention to Combat Desertification (UNCCD). The methodology applied included facilitation to develop a community-based vision for development, in terms of which the community exchange process was designed. A Facilitation Team of service providers conducted preparatory workshops, and identified potential partner communities. Two exchange visits were carried out, one focused on Rooibos production and marketing, and the other on community-based eco-tourism. Following report-back and planning workshops, emerging community-driven initiatives were supported through their formative stages. The initiatives have not only resulted in enhanced livelihoods, but the methodology has also been applied widely in a number of different contexts.  相似文献

Combating desertification requires the involvement of many people ranging from communities who experience the effects on a daily basis and scientists attempting to understand the biophysical and socio-economic causes and consequences of desertification, to developers and policy makers on all levels. In many instances, however, the understanding, approaches and actions of these different groups contradict rather than support one another. Over the period 2000 to 2002, a conference process undertaken in southern Africa brought together communities, scientists, and development workers to test the concept that they could connect and work together to combat desertification, given an appropriate framework. The conference was a success, and communities, scientists and developers did exchange experience, knowledge and information. Many lessons were learned, although some pitfalls were experienced. Time, funding, enhanced communication, and good will are the primary ingredients for ensuring that different sectors complement one another in their efforts to combat desertification.  相似文献

Field experiments were carried out in the vicinity of anisolated building using open-path and point monitoring airpollution detectors to measure concentrations of a tracer gasreleased from a source located either on the building or at thedownwind face of the building. Experiments were conducted underneutral or slightly unstable weather conditions. Either threeor five fast-response point monitors were located along thebeam path of an open-path instrument, in the wake of thebuilding. Experiments were performed with different sourcelocations, detector locations and building orientations to thewind. Visual comparison of data time series showed that datafrom the two types of instruments followed similar trends. Thebest degree of correlation occurred for an averaging timesimilar to the response time of the open-path monitor. Meanconcentrations detected by the open-path instrument weregenerally in very good agreement with the path averaged meanconcentrations from the point monitors. The point monitors werealso capable of providing time-resolved data needed to describedetailed concentration fluctuation statistics.  相似文献
