《巴厘行动计划》以来适应气候变化谈判进展及未来需求分析

回顾了《巴厘行动计划》以来形成的与适应气候变化议题相关的国际决议及谈判进展,分析了这些决议对推动发展中国家适应气候变化进程的可能作用和面临的障碍,综述了发展中国家和发达国家对“2015气候协议”的利益诉求和建议。作者认为：《巴厘行动计划》以来,《联合国气候变化框架公约》下适应气候变化方面的谈判取得了较明显的进展,建立了适应委员会、国家适应计划进程和应对损失与危害的国际机制等;资金、技术研发、推广和使用、政策法规、机构设置与能力、信息等是提高发展中国家适应气候变化的限制因素;资金、技术转让和能力建设仍是“2015气候协议”谈判的重点和难点。针对非洲集团和小岛屿国家联盟全球适应目标和应对气候变化造成的损失与危害的补偿的提议,作者建议加强科学研究,开发评估方法和工具,探讨气候自然变率和人类活动导致的气候变化影响的归因;同时建议中国进一步加强适应气候变化的南南合作。     

"中国地壳运动观测网络"区域网GPS联测数据的处理

介绍了"中国地壳运动观测网络"1999年区域网GPS联测数据的基本情况,并采用所给定的处理方案对此次联测数据进行了处理.计算结果表明:点位坐标重复性在南北方向为2.0 mm,东西方向为3.0 mm,高程方向为5.6 mm;基线重复性达到1.76 mm+1.78L×10-9 mm,基线分量重复性南北方向为1.40 mm+1.05L×10-9 mm,东西方向为2.14 mm+1.56L×10-9 mm,高程方向为4.69 mm+2.18L×10-9 mm.     

中国食管癌死亡率与水污染的空间相关分析（英文）

Esophageal cancer exhibits one of the highest incidence and mortality rates in China.Malignant tumors caused by esophageal cancer,and the relationship to environmental factors has been the focus of many public health studies.This study applied spatial analysis to ascertain the relationship between water pollution and esophageal cancer mortality rates nationwide.We employed two datasets,including a national investigation of esophageal cancer rates and distribution,and national water quality grades in China's primary rivers and lakes.Esophageal cancer data were grouped based on different water quality grades,which included a scaled buffer distance from rivers and lakes.Non-parametric correlation analyses were performed to examine the presence or absence of the following correlations:(i) esophageal cancer mortality and buffer distance from rivers and lakes;and(ii) esophageal cancer mortality and water quality grade values.The present study revealed a significant positive correlation between widespread water pollution and esophageal cancer mortality nationwide;and a significant negative correlation between esophageal cancer mortality,and buffer distance from rivers and lakes.     

基于数值模拟的黄河下游不同情景溃堤洪水特性

The lower Yellow River still faces the threat of flood due to the unusual precipitation caused by global environmental change, river channel sedimentation, hidden danger in the dike and unfavorable river regime of ＂hanging river＂. According to the characteristics of the dike-break flood of the Yellow River, this paper has simulated, in six different scenarios, the dike-break flood routing by inputting the terrain data, typical historical flood data and land use data of study area to two-dimensional unsteady flow model. The results show that： firstly, the routing process of flood will occupy other rivers on the way and return to the rivers after reaching the lower reaches; secondly, in the same river reach, flood inundating area of north band is bigger than that at corresponding location of south bank under the same historical flood; thirdly, it is different in the degree of flood inundation in different regions due to different geographical locations in flood plain; fourthly, the area of mainstream where flood is deep and flow velocity is quick is relatively smaller, but the area of non-mainstream, where flood is shallow and flow velocity is slow, is relatively big; and finally, the possible influenced area of the dike-break flood is 141,948 km^2.
