Wetland use and impact on Lake Victoria, Kenya region

This article reports on a study of wetland use and impact on Lake Victoria conducted in March and April 1995. A field survey and interviews were used to study wetland use and their impact on Lake Victoria. This article identifies management issues and establishes a broad vision for the future. It also addresses the need to balance the competing demands for wetland use and development with the need to conserve a healthy and functional Lake Victoria. Investment proposals are made that would minimize destruction of the wetlands and negative impacts on the lake. General recommendations for planning and management issues, as well as suggestions of specific research needs that should form the basis of action and investment initiatives, are given.     

湿地保护范围的量化确定方法

本文探讨了一种定量确定湿地保护范围的方法。首先根据区域地形地貌和水环境等自然条件初选数个可能的湿地保护规模的方案，然后计算各方案表征社会经济、生态环境和水环境条件的6个特征指标：湿地初级生产力产值、淹没投资、环境影响指标、蓄滞洪水量、湿地补水难度系数和湿地水体更新难度系数。最后采用灰色系统关联度法和权重图解法量化确定整体效益相对最佳的湿地保护规模的方案。文中以吉林省查干湖湿地为例进行了计算，取得了较符合实际的计算结果。     

Temporal changes in macroinvertebrate assemblages following experimental flooding in permanent and temporary wetlands in an Australian floodplain forest

The River Murray, Australia, is a highly regulated river from which almost 80% of mean annual flow is removed for human use, primarily irrigated agriculture. Consequent changes to the pattern and volume of river flow are reflected in floodplain hydrology and, therefore, the wetting/drying patterns of floodplain wetlands. To explore the significance of these changes, macroinvertebrate samples were compared between permanent and temporary wetlands following experimental flooding in a forested floodplain of the River Murray. Weekly samples from two permanent wetlands and four associated temporary sites were used to track changes in macroinvertebrate assemblage composition. Non‐metric multidimensional scaling was used to ordinate the macroinvertebrate data, indicating consistent differences between the biota of permanent and temporary wetlands and between the initial and later assemblages in the temporary sites. There were marked changes over time, but little sign that the permanent and temporary assemblages were becoming more alike over the 25‐week observation period. The apparent heterogeneity of these systems is of particular importance in developing river management plans which are likely to change flooding patterns. Such plans need to maintain a mosaic of wetland habitats if floodplain biodiversity is to be supported. Copyright © 2002 John Wiley & Sons, Ltd.

天津湿地现状及其保护利用对策分析

由于近年来气候连续干旱和长期人类不合理的开发利用,目前天津湿地存在着面积减少、污染严重和生物多样性下降问题。为了科学合理地保护利用天津湿地,必须加大宣传力度、制订政策法规、建立管理机制、增加生态用水、加强生物措施建设、划定重点保护区、保证必要的资金投入和扩大对外合作和交流等。     

湿地保护与我国水资源安全

一、我国湿地的基本概况 湿地是泛指陆地系统与水体系统相互作用形成的、具有陆地系统与水体系统间过渡性质的特殊系统。主要包括地表经常和季节性积水、生长和栖息喜湿生物、土壤严重潜育化的地段,主要包括沼泽地、河湖滩地、泥炭
