生态农场的建设与可持续发展

黑龙江省庆阳农场位于延寿县东部,总土地面积为7640公顷,但由于连续多年不停息的耕种,农场良好的生态环境遭到破坏,直接影响到农场的持续发展.建设生态农场是恢复生态环境,实现农场持续发展的根本途径.     

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.

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]
