大庆湿地景观动态变化

摘要

基于遥感技术(RS)和地理信息系统(GIS)平台,以2007年SPOT5影像和Landsat TM5遥感图像为基础数据源,结合1986年和2001年数据资料,分析了近20年大庆湿地面积的时空演变过程.针对目前斑块特征对湿地现状进行分析,找出湿地存在的问题,从建立稳定的湿地生态系统、建立重点水域的污染系统控制工程、实施油田开发区退化湿地生态恢复、开展湿地保护宣传教育四方面给出合理建议,从而为有效地保护大庆湿地生态系统及其环境功能提供科学依据.%Based on the technology platfom of Geographic Information Systam and Remote Sensing .using the Landsat TM sensing image and SPOT 5 of 2007, and the data of 1986 and 2001 as the basic data resources, this paper studied the dynamic change of the ecological landscape pattern in the last 20 years.
