为防震减灾事业做好科普宣传--南京地震科学馆的建设与发展

从1989年江苏省第一届科普宣传周起,南京基准地震台都被列为宣传周期间重点对外开放单位.于是,南京地震台克服重重困难,筹建了地震科学馆.十多年来在江苏省地震局和有关单位的大力支持下,由最初腾出地震台的会议室和几间办公室发展到有530平方米的展室和多功能厅,展出内容也得到丰富.同时,地震科学馆在防震减灾宣传中取得了一定的社会效益.     

胶州湾入海污染物总量控制研究

在胶州湾水质数值模拟的基础上,建立了污染物总量控制模型.计算了各个点源的响应系数,分担率及环境容量.结果表明,胶州湾内COD各入海污染源均有余量,不需要削减.胶州湾东北部N、P污染较严重,污染物入海总量已经超过海域的环境容量.研究结果将为胶州湾污水排海、海域水质管理、总量控制规划编制提供科学依据.     

抓住机遇 开拓创新 努力提高国土资源对可持续发展保障能力

加入WTO我国国土资源管理工作面临新的形势、新的任务、新的要求。该文对我国加入WTO后土地、矿产、海洋等国土资源形势以及改进和加强管理工作面临的机遇和挑战进行了分析,提出将进一步加强国土资源调查评价,加快国土资源市场建设,严格实施资源规划,加强宏观调控,积极实施“走出去”、“引进来”的战略,深化改革,推进依法行政,大力推进国土资源科技进步,努力提高国土资源对经济社会可持续发展的保障能力。     

铜川新区建设生态城市发展模式研究

以可持续发展为指导思想，结合生态城市的内涵，提出城乡一体化和生态生产的城市发展思路，建立了土地容量与人口适宜容量数学模型。根据铜川新区具有的自然优势，从自然—社会—经济复合生态角度，针对铜川新区的土地容量与人口适宜容量，探讨了将铜川新区建设成为一个环境优美、人口适宜的生态城市的发展模式。     

应用BP神经网络预测嵌岩桩竖向承载力的研究

利用BP神经网络,建立了嵌岩桩竖向承载力预测的BP神经网络模型,采用嵌岩桩竖向承载力的实验数据对网络进行了训练,并以此训练好的BP神经网络对嵌岩桩承载力进行了预测。预测结果表明,该模型具有很高的预测精度,为预测嵌岩桩承载力提供了一种新的方法。

Mitigation of the Impact of Tropical Cyclones in Northern Australia through Community Capacity Enhancement

Community mitigation of hazard impact requires hazard knowledge and preparedness on the part of the members of diverse and complex communities. Longitudinal research in the tropical cyclone prone north of Australia has gathered extensive datasets on community awareness, preparedness and knowledge, in order to contribute to education campaigns and mitigation strategies. Data have been used to identify issues of vulnerability to cyclones and capacity to deal with the hazard. This has been developed as a community vulnerability and capacity model that may be applied to diverse communities in order to assess levels of capability to mitigate and deal with the cyclone hazard. The model is presented here in a simplified form as its development is evolving and ongoing.     

Institutional and cost implications of multi-project baselines

Starting from a theoreticalnotion of capacity building this paperfocuses on the implications ofmulti-project baselines for costs andinstitutions. Availability of data and thelevel of data aggregation determine to alarge extent the cost of derivingmulti-project baselines. For localinstitutions this implies that theircapacity development needs are linked todecisions made on strictness of baselines.The initial higher costs of multi-projectcalculations in the development stage areeasily offset once more projects will usesuch a baseline. This paper argues theseinitial demands are not as high asexpected. Multi-project approaches willreduce transaction costs, especially forsmall-scale projects, will reducevalidation costs and likely reduce humanresource demands in other stages of theproject cycle.     

Genetic amniocentesis following multifetal pregnancy reduction to twins: Assessing the risk

Fifty-three patients who elected to reduce their pregnancies to a twin gestation in our centre are known to have subsequently undergone genetic amniocentesis. Five of these patients lost their entire pregnancy following the genetic amniocentesis procedure. This is equivalent to a 9·4 per cent pregnancy loss rate for reduced twin gestations in comparison with an expected loss rate of 2 per cent for non-reduced twin gestations.
