天山乌苏段火山泥元素组成及含量分析

采用能量色散型X射线荧光光谱分析（EDXRF）对新疆乌苏天山泥火山土壤样品的元素含量进行了测定。采用单指标评价指数法和内梅罗综合指数法,对新疆天山乌苏段火山泥中的重金属的种类和含量进行了研究,结果显示：Cd、As、Cu元素的含量达到土壤环境质量评价的二级标准,Hg、Pb、Cr、Zn、Ni元素的含量达到土壤环境质量评价的一级标准,乌苏天山火山泥综合评价达到二级标准。将火山泥的元素含量与新疆地区不同土质的土壤元素含量进行比较,与干旱区不同省份的土壤元素含量进行比较,分析了火山泥元素组成及含量的成因。     

Tracking embodied carbon flows in the Belt and Road regions

In the past few decades, economic globalization has driven rapid growth of cross-border trade and a new international division of labor, leading to increasing inter- country embodied carbon flows. Multi-region input-output (MRIO) analysis is used to identify embodied carbon flows between major world regions, including seven regions along the Belt and Road (BR), and the spatial distribution of production- and consumption-based carbon intensities. The results show that current embodied carbon flows are virtually all from BR regions to developed countries, with more than 95% of world net embodied carbon exports coming from BR regions. Consumption in the United States and European Union countries induce about 30% of the carbon emissions in most BR regions, indicating that the former bear a high proportion of consumers’ responsibility for the carbon emitted in the latter. For this reason, measuring environmental responsibilities from consumption rather than a production- based perspective is more equitable, while developing countries should be given a louder voice in the construction through dialogue and cooperation, in part in the context of the Belt and Road Initiative, of an inclusive global climate governance system.     

中国游艇俱乐部区位特征研究

通过对中国游艇俱乐部相关数据的收集与分析,探讨游艇俱乐部的区域宏观区位特征和城市微观区位特征,并揭示出区位特征的核心影响因素。主要结论为：中国的游艇俱乐部主要集中在三大经济区,其中广东、海南、山东、上海和浙江等地的游艇俱乐部综合能力较强。中心城区和近郊区是游艇俱乐部的主要聚集地,纯游艇俱乐部和地产型游艇俱乐部为主要载体,有泊位的与无泊位的俱乐部在区位上高度重合。影响游艇俱乐部区位的因素既包括区域自然资源环境、经济水平、旅游业发展、上游游艇制造业,也包括游艇产业相关政策及区域海洋文化等因素。     

由“撤县建区”引起对中国城市郊区化的思考

江苏省最近一轮的城镇体系规划中提出的“撤县建区”方案,这一方案引起了笔者对有中国郊区化的思考。在本文中作者主要阐述了四个方面的内容,首先指出中国的大城市已经进入了郊区化阶段;其次将中外郊区化进行了系统比较;接着论述了郊区化的利与弊,最后,在前文基础上,提出了走中国特色的城市郊区化道路需采取的一系列措施。     

The δ18O in the Guliya shallow ice core during the prevailing summer monsoons and sea-air interactions

The correlations of the δ¹⁸O_max in the shallow ice core from the Guliya ice cap on the Tibetan Plateau with the global sea surface temperatures (SST) and height at the 500 hPa over the Northern Hemisphere were analyzed. The correlated regions on oceans that have a significant influence on the δ¹⁸O_max in the Guliya ice core are all located in ocean currents, or convergent regions of currents. They are the eastern Equatorial Pacific, the Northern Pacific Current, the Hot Pool in the eastern Indian Ocean, the Mozambique Current, the Northern Atlantic Current, the Canary Current and the Atlantic Equatorial Current. The δ¹⁸O_max in the Guliya ice core has negative correlations with the SST located in the lower latitudes, and positive correlations with the SST in the middle latitudes. The correlated areas at the 500 hPa that have a great impact on the δ¹⁸O_max are located in the subtropical highs over the mid-low-latitude oceans and the long-wave trough area over Balkhash Lake, where there are marked negative correlations between the heights in those areas and the δ¹⁸O_max. The influencing mechanism is displayed by the diversity of the vapor origins transported to the Guliya region. The strengths of the European ridge and the ridge over Baikal Lake have notable positive correlations with the δ¹⁸O_max. The two systems indirectly influence the vapor transportation towards the Guliya region by the adjustment of long-wave trough and ridge.

SOME RESULTS OF APPLICATIONS OF STATISTICAL METHOD TO CLIMATE CHANGES AND SHORT-TERM CLIMATE PREDICTION IN CHINA

In recent years, much attention has been paid to climate changes and short-term climate prediction, because the large area climate anomaly has, constantly occurred in many areas of China and of other places in the world since the 1960's. From 1974 to 1981, ten national meetings on climatology in China were held. More than 100 papers were presented at each of these meetings. Two collections of papers presented at these meetings have been printed. At present, in addition to research at meteorological institutes and universities, the research of climate changes and short-term climate prediction is also being carried out in the weather bureaus of the 30 provinces and autonomous regions (including Taiwan). The gaps in the research in this field in China have been filled.
