我国湿地评价研究综述

湿地评价研究已成为新世纪湿地科学前沿研究领域的热点问题。近年来 ,随着对湿地认识的不断深入 ,我国湿地评价研究内容不断丰富 ,研究水平提高幅度较大 ,研究方法由过去仅局限于湿地特征描述的定性评价 ,发展到湿地价值评价、湿地生态系统健康评价、湿地环境影响评价以及湿地生态风险评价等方面 ,3S技术和数学方法在湿地评价研究中也得到了较为广泛的应用。今后我国湿地评价研究应侧重于湿地评价理论、湿地评价指标体系和模型、湿地对比评价研究、退化湿地评价研究、湿地与全球气候变化以及新技术和新方法应用等方面

A review on the study of wetland assessment in China

Researches on wetland assessment were become hot points in the field of wetland science.In recent years,with the deep development of the study on wetland,much progress has been made in the content and the level of wetland assessment.The measures have been changed from single qualitative assessment on wetland resource to the quantitative assessment,the wetland value assessment,the ecological healthy assessment,the environmental impact assessment and the ecological risk assessment and so on.3S techniques and mathematics were widely applied.In the future,the research on wetland assessment should focus on the theory of wetland assessment,the index and model of wetland assessment,comparison studies among different regions,the assessment of degraded wetland,wetland and global change,and the application of new techniques and methods.
