简介：红树林湿地是分布于亚热带、热带滨海地区的典型湿地,具有其它湿地类型所不具备的特殊的演化过程,形成独特的水文、土壤和植被特征.由于人类活动的影响,近年来,我国红树林湿地出现了面积锐减、生态系统结构简化、生物多样性降低、生态功能退化等严重问题,使红树林湿地的可持续利用面临严重挑战.从湿地生态、湿地功能及湿地开发利用、保护与管理等方面评述我国红树林湿地生态系统的研究现状,探讨我国红树林湿地未来研究的主要科学问题,进而明确红树林湿地可持续利用研究的方向和途径.

简介：通过对传统污水处理的生化二级处理系统与人工湿地污水处理系统分析和比较,可以看出污水处理厂具有投资大、运行成本费高、并难以解决水质'富营养化'的缺点,而人工湿地污水处理系统具有投资少、运行成本低、出水质量好的优点.根据南充城市化进程的具体形势,提出在规划和建设生态城市方案中,建设人工湿地污水处理系统的设想,并就人工湿地的规模、区位选择、活水公园设计、预期效益分析等问题进行了详细的论证和阐述.

简介：通过测定汞在吉林省双阳泥炭和黑龙江省洪河农场泥炭吸附等温线,利用热力学函数关系计算汞在两种泥炭等量吸附焓、吸附自由能和吸附熵,结果表明汞在泥炭中的吸附是配位离子吸附,且反应极易发生,由于泥炭残体组成和性质的差异,汞在两种泥炭中的吸附性能也有一定区别.最后讨论了泥炭吸附汞的热力学基本原理及由此所产生的汞对沼泽湿地环境和生物的效应.

简介：以新济洲湿地为例,研究了长江洲滩湿地生态恢复的内涵,提出了生态恢复工程方案.新济洲湿地位于长江下游南京市江宁区段,由于自然因素和人为因素的影响,该湿地结构和功能发生了明显的变化.通过对新济洲湿地的野外研究,分析了退化湿地生态系统的特征,从湿地生境、生物、结构与功能方面阐述了生态恢复的总体构想,研究了湿地恢复的工程手段与可持续利用模式.新济洲湿地生境恢复包括栖息地、基底、水体和土壤的恢复;湿地生物恢复途径有提高植被覆盖率、控制外来物种和保护野生动植物;湿地结构与功能恢复内容包括生态序列重建,生态系统、湿地景观与生物多样性恢复.湿地恢复的工程手段有景观建设、功能区建设、生态定位站、血吸虫防治、植被移植、防护林和河道整治等;湿地可持续利用模式包括桑基鱼塘、生态农业与生态旅游.
