西南三省山地剖面气象资料管理服务系统

利用云、贵、川三省主要山系哀牢山、大娄山、大巴山的２５个山地剖面气候站点，自１９８７－２１－１９９０．２－２８，１９个气象要素的逐日观测资料，首次建立了西南三省山地剖面气象资料管理服务系统。系统具有资料管理、气候统计分析、资料比较等功能，适于科研、气候资料业务管理应用．     

气象因子对近地面臭氧污染影响的研究

本文通过对１９９３年春季和春夏之交的O3浓度逐日变化、日变化和气象因子关系的分析，提出了影响O3浓度的主导气象因子和不同情况下形成高浓度O3的主要因子，提出了大风速对逐日变化中O3浓度特高及浓度日变化峰值的重要作用，并指出高温、低湿、小风并不是在所有情况都是促成高浓度O3的因子。另外，雾也可以成为近地面O3浓度增值的因素，主要原因是雾内湍流发展将高浓度O3大量输向下方。     

梧州市森林火险气象预报

使用１９８０－１９９１年森林火灾及相应的气象资料，分析了森林火灾与有关气象要素的相关性。在此基础上，计算了森林火险天气预报指标，建立了预报模式，开展了森林火险天气等级预报。经试用效果较好。     

厦门酸雨与气象要素的关系及污染源的分析

根据厦门市１９８３－１９９１年９年春雨，梅雨及台风雨酸度的观测结果，结合各场雨水同步观测的气象要素资料，分析各类型雨水酸度与气象要素的关系。同时依降水的酸化原理估计了外来源及局的地源对厦门酸雨形成的贡献。     

用现代企业制度改造和重塑多种经营企业加快发展部门产业经济

地勘经济改革的战略思想是建设适应社会主义市场经济的新体制，将现有的地勘队伍组建为＂地质找矿的野战军＂和＂实行企业化的地方军＂．分别按事业机制和企业机制运行。如何实现地勘单位（地方军）的企业化，笔者认为首先必须用现代企业制度改造和重塑现有的多种经营企业，并分析了困难和有利条件，提出了相应的对策和措施，使多种经营企业真正成为符合现代企业制度要求的经济实体。加快发展部门产业经济，才能逐步推进地勘单位的企业化。     

MONITORING OF 1991 EASTERN CHINA FLOODING WITH POLAR ORBITING METEOROLOGICAL SATELLITES FY-1 AND NOAA

With polar orbiting meteorological satellites FY-1 and NOAA,flooding was monitored in the areas of the HuaiheRiver basin and the Taihu Lake region during June and July 1991.All satellite images from FY-1 and NOAA for concerned areas before and during flooding were examined.Thoseof cloud-free,with small amount of cumulus or thin cirrus were selected to exam the situation.Navigation and projec-tion were carefully performed,to ensure the projected images at different time overlap accurately with each other in 1—2pixels.Channel 1 (CH1) and Channel 2 (CH2) data of FY-1 and NOAA satellites with wavelength of 0.58—0.68μm and0.725—1.1μm were used to monitor the flooding.Albedo of Channel 2 and normalized vegetation index (NDVI) wereadopted as indicators to identify water body from land.With histogram and man-machine interactive methods,analysiswas done.In cloud-free condition,the two indicators identified the same area and scope of the water body.Totally cloud-free image in a large area is quite rare.To understand flood process,it is necessary to use more fre-quent images.It was investigated to distinguish water from land in partly cloudy condition.The result showed that whenthere is small amount of cumulus or thin cirrus,satellite images are still valuable in monitoring water body.In case ofmonitoring area covered with cirrus,vegetation index is useful,and while there is small amount of cumulus on land,albedo of Channel 2 can be used.Ten images from May 16 to August 18 of 1991 were examined.The results show that in the Lixiahe area,JiangsuProvince,the area submerged in total was the largest;along main stream of the Huaihe River,the Chuhe River,andaround the Chaohu Lake,a large percentage of area submerged;while in the Taihu Lake area,less field submerged.Flood monitoring was performed for 87 counties in the region concerned.These counties were put in order accord-ing to the percentage of submerged area in total.This order showed the extent of disaster at one view point.     

贵州省矿业开发引起的环境问题及其成因探讨

矿业开发给贵州省造成严重的生态环境问题,主要包括环境污染,矿业荒漠化和环境地质灾害。虽然贵州省矿产开发的历史比较悠久,但解放前的生态破坏和矿业污染仅局限在个别地区,解放后出现的三次大规模资源环境破坏,给贵州省矿业可持续发展带来严重影响,特别是改革开放以来矿山资源的无序开发对环境的危害最重。导致贵州省矿业环境问题的主要因素包括：矿产资源价值的严重扭曲,乡镇企业的超常规发展,部分政府官员的权力寻租,以及资源导向型的脱贫模式等。     

Mapping the Globalization of the Temporary Staffing Industry*

Very little is currently known about the globalization of the temporary staffing industry, a strategically significant sector given its role in promulgating wider labor market flexibility. This article starts to rectify this research lacuna in four ways: by conceptualizing the international expansion of temporary staffing and comparing it to other business service sectors, by identifying and mapping the top twenty transnational staffing agencies, by offering a typology of the leading transnational agencies based on their functional and geographic characteristics, and by charting a research agenda for future work on this sector.     

影响我国主要粮食作物产量的气象因子研究
