底泥疏挖工程对草海水生生态环境的影响预测

草海底泥疏挖工程的实施，必将对草海水生生态环境产生影响，预测结果表明，疏挖后草海水质有所改善，基本达到国家地面水Ｄ类标准，但相当长时间内仍疳保持富营养化状态，生态系统短期内改善不大，需较长时间，依靠人工强化恢复和自然恢复。草海水生生态系统方能逐步恢复。     

Ecological networks and greenways in Europe: reasoning and concepts

The paper gives an overview of approaches towards ecological networks throughout Europe.It does not intend to present a complete picture,but to highlight comon developments within countries and regions and show common principles and differences between countries and regions that have to be taken into account when developing a joint European intiative,Countries or regions that have not been included can be active in the same way ,but information was not accessible to be authors for different reasons.This overview shows the comparable trends in decline of landscapes and the diversity in approaches to biodiversity conservation and nature conservation planning.Understanding the differences and common issues are of utmost imprtance to generalise common principles and to understand the way neighbours and other European partners approach problems.     

大学生生态教育现状调查研究

环保教育是全方位的环境保护和可持续发展意识的教育，是全民教育、全程教育和终身教育，大学生的生态教育是大学生素质教育的重要环节。通过对云南大学1000名学生的问卷调查，分析了大学生生态意识的现状并提出大学生生态教育的对策。     

海水养殖对近岸生态环境的影响

海水养殖对近岸生态环境的影响一般包括它对养殖水休自身生态环境的污染和对近海水域生态环境的破坏两个方面。它对养殖水体的污染主要是营养物的污染、药物的使用污染以及底泥的富集污染 ,而它对近海生态环境的破坏主要表现为对近岸海洋生物生态系统的破坏和沿岸滩涂、红树林资源的破坏。本文就海水养殖对近海生态环境的影响作了详细的综述 ,然后从调整生态结构和改善管理水平出发 ,提出了为海水养殖可持续发展可采取的措施和对策。     

Spatial distribution of ecological security status assessment of West-Liaohe River based on geographic information system

Eco-security assessment is a hot research area in resource and environmental science, which involves data with much spatial, non-linear, and random features. Geographic information system (GIS), as a useful tool to analyze and manage spatial information, has a superior advantage in this field. A case study in the western part of the Liaohe River featuring a method of eco-security spatial differences (ESSD) based on GIS is developed in this paper. The method includes four steps: 1) developing the pressure-state-response (P-S-R) framework with site data; 2) digitizing West-Liaohe River and setting its GRID database of ecosecurity assessment indicators; 3) figuring out the relative membership degree (RMD) of eco-security indicators by using the analytical hierarchy process with the weight of indicator; 4) classifying the security zone and mapping the assessment result of eco-security status in grid by GIS method of assigning and clustering. The visual spatial differences of eco-security based on GIS enables decision makers to know the status of eco-security better in making policies for achieving sustainability. __________ Translated from Environmental Science, 2005, 26(5): 28–33 [译自: 环境科学]

松华坝水库水体营养状况评价与污染控制

采用中国环境监测总站<湖泊(水库)富营养化评价方法及分级技术规定>(2001年12月)中的综合营养状态指数法评价2004年松华坝水库水体的营养状况枯水期均处于贫营养状态;平水期处于贫营养和中营养状态;丰水期均处于中营养状态,出现了富营养化的征兆.针对丰水期水体已面临轻度富营养化的威胁,提出防治对策与建议.
