作为极度缺水的鄂尔多斯盆地西南缘地区,针对白垩系含水地层采水的供水井很多,但供水井水质恶化和水量减小的现象较为普遍,其原因主要是井身结构严重不合理所致。通过对造成供水井质量恶化的原因分析,找出了止水方法的不合理性与泥岩缩... 作为极度缺水的鄂尔多斯盆地西南缘地区,针对白垩系含水地层采水的供水井很多,但供水井水质恶化和水量减小的现象较为普遍,其原因主要是井身结构严重不合理所致。通过对造成供水井质量恶化的原因分析,找出了止水方法的不合理性与泥岩缩径造成井身变形而致水量减小的问题实质,提出了科学合理的成井方案,从而有效地解决了供水井质量恶化问题,提高了供水井使用寿命。 展开更多

This article looks at how population movements are addressed by the Sendai Framework for Disaster Risk Reduction 2015–2030(SFDRR), and highlights some of the potential implications of the SFDRR on disaster risk reduction(DRR) and mobility management work. The article looks at the operational implications of the SFDRR text and covers issues of including migrants in DRR work;informing urban development about current and future mobility trends; managing relocations, evacuations, and displacement to prevent future risks and reduce existing ones; and preparing for and managing disaster-induced population movements to reduce the direct and indirect impacts of natural hazards. Overall, the references to human mobility within the SFDRR show an evolution in the way the issue is considered within global policy dialogues. Both the potential of population movements to produce risk and their role in strengthening the resilience of people and communities are now clearly recognized. This is an evolution of previously prevailing views of mobility as the consequence of disasters or as a driver of risk. While some implications of the DRR-mobility nexus might still be missing from DRR policy, population movements are now recognized as a key global risk dynamic. 展开更多
