摘要
利用网络文献数据库,对1995年以来以CNKI为主的数据库检索的相关文献进行综述,从遥感在湿地分类和制图、湿地监测、湿地生态及技术和方法等方面的应用归纳出目前湿地遥感研究存在如下问题:地理时空分布不均,以中小尺度为主;区域特殊性研究较多,缺少区域共性研究;研究方法可操作性差;学科综合少;湿地信息系统不健全。基于以上问题,湿地遥感研究趋向以下方向:大尺度监测和制图;结合湿地特征,实现区域模块化;建立湿地信息系统平台,加大湿地开放型遥感应用;遵循湿地系统性,加强湿地综合和对比研究;重视学科综合和合作;重视技术交互,实现湿地遥感应用发展。
Due to the objective,highly effective, real-time and macroscopic traits, the remote sensing has been gradually approved and largely promoted in wetland research. Retrieving document with the platform of web database since 1995 ,the RS-based re search of wetland is discussed mainly on several aspects：classification, mapping and monitoring of wetland, ecosystem, applica- tion of remote sensing technology and methods. The main problems include geographical space unevenly distributed with the me- so-microscale primarily; the subject research and study is the main part for the regional study,and lack of integrated and com- parative study;more mechanical imitation for the methods,and lack of maneuverability;less intelligent application of RS. Related research prospects should be to carry out such as monitoring and mapping on large scale,characteristic methods innovating con- bined with the trait of wetland,establishing combining platform,increasing the application of open RS, to give more attention on wetland system, to expand integrated study on region;to emphasize the ability of discursion, and to increase the application of in- telligent RS. The future potential study is analyzed aiming to better understanding the current development of wetland science and serving for wetland remote sensing research towards wetland sustainable management.
