油库上装密闭发油鹤管的研发

根据油库油气回收系统的工艺要求,分析了现有油库上装发油系统实现油气密闭收集的技术难点及需要解决的问题。借鉴下装式发油的技术特点,研发了上装密闭发油系统,提出了鹤管系统及油罐车改造方案。在对现有油库上装发油鹤管不进行大规模改造的前提下,实现了上装密闭发油,经现场应用,效果良好。     

Of timelines and timeliness: lessons from Typhoon Haiyan in early disaster response

Typhoon Haiyan struck the Philippines on 8 November 2013 with maximum sustained winds of 235 kilometres per hour, adversely affecting at least 11 million people and displacing some 673,000 in the central regions of the country. The disaster clearly overwhelmed the Philippine government despite its seemingly well‐crafted disaster management plan. Using timelines of different organisations, this paper identifies gaps in the government's response, mainly due to its failure in coordinating and managing relief operations, which adversely affected its effectiveness and efficiency in the delivery of critical goods and services following the disaster. The paper also demonstrates how non‐governmental organisations (NGOs), the United Nations, foreign governments and other organisations provided assistance, mainly through aid niching, to cover the government's shortcomings. The paper recommends a paradigm shift in the government's disaster response by integrating collaborative arrangements between government agencies and NGOs, and giving local governments the lead role, with the national government as support, in disaster planning and response.     

Perspectives on policy framework for trans-boundary water quality management in China

In river basins that cross jurisdictional boundaries, water quality degradation has become a crucial problem and results in intensive competition among water users, especially in developing countries. Under this situation, implementing water quality management and control across jurisdictional boundaries can strengthen watershed pollution controls, and prevent pollution from being passed on and promote active pollution control within the related jurisdictional regions. This study examined the limitations of the current trans-boundary water quality management system in China and reviewed the planning and implementation of two pilot integrated trans-boundary water management systems established in the Jiangsu and Zhejiang provinces. Based on our findings, we proposed a new policy framework for trans-boundary water quality management. As a first step toward integrated watershed management in China, this policy framework can help assess the actual water pollution status of various regions and serve as a basis for an integrated watershed management system. The framework can be easily applied in other countries with trans-boundary water pollution issues, particularly in the context of developing countries.

缅甸与我国接壤地区森林砍伐遥感监测分析

采用HJ星数据、Landsat TM数据以及MODIS卫星数据,对距中缅边境线100公里的缅方一侧区域进行了监测和分析,结果发现:监测区2001-2009年森林覆盖面积呈下降趋势,但是森林覆盖率降幅有所放缓;监测区内每年的森林火点分布广,且燃烧过的林地,大部分变为农田,一些农田撂荒成为草地。分析认为,当地传统的刀耕火种耕作方式也是该地区森林面积减少原因之一。

1998年长江流域洪水灾害成因分析

通过实测气象,水文数据分析和洪水期雷达卫星影像判读,论述了１９９８年长江流域洪水的雨情,水情和灾情的主要特征,并与１９９４年的相关数据进行了比较,可以认为,１９９８年长江流域洪水是由异常降水引起的,其洪水灾害的主要物征为高水位,长历时,大洪量,１９９８年长江干流洪水总量与１９５４年规模相当。
