摘要 遥感技术是湿地资源调查与监测的有效手段之一。以遥感影像资料为基础,结合G IS技术对鸭绿江口滨海湿地进行定量化研究,查明湿地的类型分布、面积,分析其1989—2000年期间土地利用的变化。结果表明:虾田、居民地、滩涂面积增加;芦苇沼泽、水田、浅海水域面积减少;湿地生态环境遭到破坏。这些主要是由城市扩张和经济增长所致。天然湿地的减少,使依赖于湿地生存的动、植物种类大大减少。为保护湿地生态环境,应严禁毁苇开荒,逐步退耕还苇,加强管理,合理开发利用,使本区可持续发展。 Remote sensing technology provides an effective method for survey and monitoring of wetland resources. Integrating RS and GIS technologies, wetland information in seaside wetland around Yalujiang River estuary is obtained quantitatively. The types, distributions and areas of wetland are investigated. Change in the land utilization from 1989 to 2000 is analyzed. With the increase of shrimp field, residential and tidal-fiat area, and the decrease of reed marsh, paddy field and shallow sea area, the ecology environment of seaside wetland around Yalujiang River estuary has been damaged. Urban expansion and economic development are mostly responsible for these damages. The decrease of natural wetland made many species of animals and plants relying on wetland reduce greatly. For the protection of ecology environment, it is necessary to forbid destroying reed and reclamation, convert cropland to reed, adopt rational exploitation and utilize wetland resources, and obtain the objective of sustainable development.
