对中国城市环境地质工作的思考

本文回顾了国内外城市地质工作的发展历程，阐述了中国城市地质工人的发展方向和重点工作领域。指出城市地质工作必须服务于城市（城市群，经济开发区）的规划，建设和管理，为城市社会经济可持续发展，减灾防灾提供具有针对性，实用性和超前性的基础地质资料和成果。由于中国城市的规模，性质，自然资源承载力，地质环境特征不同，城市环境地质调查，评价的对象，内容也将有所差异。归纳起来，城市地质的重点工作领域为：城市可持续发展，城市可持续发展的资源开发战略与对策，城市地质环境容量及脆弱性分析。城市地质灾害：城市地质灾害风险，影响面，易损性及对灾害的反应，城市环境变化的地质指标体系，城市环境地质综合研究：城市环境地质调查评价的新理论，新方法，新技术，城市环境地质图纱的编制。数字城市环境地质：GIS平台上的地质空间数据库，城市地质环境动态分析，评价，决策系统和地质灾害预警预报系统。

Chemical Composition and Acidity of Rain at the Gulf of Iskenderun,North-East Mediterranean

The purpose of the present work was to investigate the chemistry of rain in the Gulf of Iskenderun, North East Mediterranean, Turkey. The Gulf region has a large number of industries. Main industries existing in the region are iron and steel works, fertilizer plants, a cement plant, and several medium and mini size steel mills in addition to the international pipe line terminals. This study aims to apportion the local sources contributing to the overall pollution of the region. To this end a precipitation sampling program was started in January 2000, and over 48 precipitation samples were collected from each of 5 stations located at Iskenderun city center, Iskenderun industrial zone, Payas city center, the campus of Iskenderun Technical College and the campus of Mustafa Kemal University. Samples were analysed for pH, NO₃ ⁺, Cl^-. Ca, Al, Ba, Na, Cd, Co, Cr, Cu, Pb, Li, Mg, Mn, Ni, Zn, Fe, K. Concentrations of metal ions were determined by ICP-AES. NO₃ ^- ions and pH were determined by using NO₃ ^- selective electrode and pH meter, respectively.pH values of the collected samples at the industrial zone and at Payas city center, ranged between 5.02 and 7.38, respectively. NO₃ ^- and metal ions concentrations were highly variable. Concentrations of Ca and Fe ions were higher in the industrial zone and Payas city center. In the other three stations, concentrations of metal ions and NO₃ ^- ion were lower than that of industrial zone and the values of pH ranged between 6 and 7.4. The average pH values at Iskenderun Gulf showed that the precipitation was not acidic, because of the high concentration of Ca. The highest concentrations of Na and Cl ions were recorded in the University campus because the campus is located by the Mediterranean Sea.     

基于多媒体技术的<中国自然灾害>教育软件开发

根据社会公众对中国自然灾害信息的需求，开发了《中国自然灾害》多媒体教育软件。软件以区域灾害系统理论为指导，设计了内容框架、基本体系。通过声音、影像、动画和文本等媒体形式可向社会深层次、多角度地介绍中国自然灾害信息，普及减灾知识，增强社会防灾减灾意识。

1978—1994年分省农业旱灾灾情的经验正交函数EOF分析

本文利用１９７８～１９９４年各省、市、自治区的农业旱灾受灾面积及播种面积的资料，以旱灾受灾率（即旱灾受灾面积与播种面积之比）作为刻划旱灾灾情的指标。对标准化的旱灾受灾率进行经验正交函数分析，发现前五个典型场方差贡献达７０．７％，可以概括我国旱灾灾情的空间分布主要类型。其中，前三个典型场的正负区域分界线的大体位置分别为长城一线、秦淮线和江南丘陵北缘
