基础结构管理:美国和日本系统比较     

韩路  王庆生 《地理科学进展》1996,15(2):20-27

尽管很少有文章去比较美国的市政工程管理系统,但是美国的土木工程师和市政建设的决策者们可以向日本学习,且日本也可以向美国学习。1992年笔者作为美国赴日本市政工程考察团的成员之一,受命去考察日本的交通、城市发展、固体废弃物、住房、供排水系统工程。在日本,拜会了市政工程的领导人,而且学到了由市政工程官员们实践过的日本管理文化。  相似文献

Approaches to environmental restoration of a polluted harbour with submerged archaeology: the Alexandria case study     

El-Rayis OA  Hemeda EI  Ismael AM  Jammo K 《Marine pollution bulletin》2003,47(1-6):193-197

Many invaluable underwater buildings of archaeological interest in Alexandria were discovered in 1996 at different sites in the Eastern Harbour of Alexandria. There is a belief that the best way to protect these invaluable heritages is to transfer them to an underwater park or museum. Obviously, the execution of such a project depends essentially upon the water quality (including water transparency) improving in the future. The harbour is presently polluted by discharge of wastewater effluents from different sources. It has recently been decided to restore this important coastal area through: (1) stopping the direct discharge of wastewater effluents into this semi-enclosed harbour in 1993 and (2) gradually reducing the discharge of the municipal wastewater through marine outfalls at two sites lying at the outer sides of the harbour. Zero discharge is expected to be effective by the end of the year 2001. The present work, therefore, is a follow up of the study of water quality in the harbour after 1993: in 1996 and 1999-2000. The water quality of an open sea reference station was also studied for comparison. The results reveal occurrence of an improvement of the environmental conditions in the harbour. The water has turned from being eutrophic to mesotrophic. The harbour is expected to become meso/oligotrophic as soon as the complete cessation of the discharge from the two outside sources is attained.  相似文献   

从成果看未来——河南地理所三十年发展透视     

王庆生  荆海军  张继红 《地域研究与开发》1990,(Z2)

河南地理所筹建于1958年秋,1959年正式开展研究工作,原名为中国科学院河南分院地理研究所。1980年划归河南省科学院领导,1987年9月实行省科学院与省计经委双重领导至今。三十年来,我所紧密结合国民经济建设需要,开展了多方面的科学研究工作。截止1989年底,我所共主持完成和参与完成科研成果209项,仅1978年以来已有53项科研成果获省(部)级科研成果奖和科技进步奖。各类成果在各级领导决策和生产建设中发挥了重要作用。  相似文献

Stramonita haemastoma as a bioindicator for organotin contamination in coastal environments     

Limaverde AM  Wagener Ade L  Fernandez MA  Scofield Ade L  Coutinho R 《Marine environmental research》2007,64(3):384-398

Stramonita haemastoma was investigated as a suitable bioindicator of TBT and TPhT contamination in the tropical Atlantic Ocean by: 1. Imposex induction in healthy females after inoculation with TBT and TPhT in the laboratory; and 2. Determining incidence of imposex in S. haemastoma collected from areas with various levels of tributyltin (TBT) and triphenyltin (TPhT) and determining the concentrations of these chemical in its tissues and that of its prey, the mussell Perna pernas. Imposex intensities and organotin concentrations in tissues showed good correlation, indicating S. haemastoma as a reliable bioindicator of TBT and TPhT contamination in coastal waters. Body burden threshold of TBT and TPhT for imposex induction was estimated to be 10-20 ng g(-1).  相似文献   

A Paddock to reef monitoring and modelling framework for the Great Barrier Reef: Paddock and catchment component     

Carroll C  Waters D  Vardy S  Silburn DM  Attard S  Thorburn PJ  Davis AM  Halpin N  Schmidt M  Wilson B  Clark A 《Marine pollution bulletin》2012,65(4-9):136-149

Targets for improvements in water quality entering the Great Barrier Reef (GBR) have been set through the Reef Water Quality Protection Plan (Reef Plan). To measure and report on progress towards the targets set a program has been established that combines monitoring and modelling at paddock through to catchment and reef scales; the Paddock to Reef Integrated Monitoring, Modelling and Reporting Program (Paddock to Reef Program). This program aims to provide evidence of links between land management activities, water quality and reef health. Five lines of evidence are used: the effectiveness of management practices to improve water quality; the prevalence of management practice adoption and change in catchment indicators; long-term monitoring of catchment water quality; paddock & catchment modelling to provide a relative assessment of progress towards meeting targets; and finally marine monitoring of GBR water quality and reef ecosystem health. This paper outlines the first four lines of evidence.  相似文献
