摘要
从湿地变化监测与分类方法、湿地景观格局变化分析、湿地生态环境退化研究、湿地生态系统模型研究、湿地生态服务功能价值评估和以往研究中取得的主要成果等几个方面,总结了当前已有的湿地变化监测和分类的各种方法,并举例说明湿地变化监测的主要研究领域。同时,针对当前卫星遥感技术和计算机技术发展特点,指出以大时空尺度、高时空分辨率和高精度数值模拟为代表的遥感手段,与水文、生态、地理等手段有机结合将成为未来湿地变化监测研究领域的重点发展方向。
Wetland is an important ecosystem with great ecological value and environmental benefits.Since the 1960＇s,great changes happened to the wetlands in this world.The serious eco-environmental problems like water shrinking,biodiversity reduction,and water pollution have attracted much attention of the people.This paper summarized the existing methods for wetland change monitoring and classification from the view of the wetland landscape pattern change,wetland ecological degradation,wetland ecological system model,wetland ecological service function and the main achievements in previous studies.It also illustrated the main research fields of wetland change monitoring.In addition,aiming at the characteristics of the development of satellite remote sensing and computer technology,this paper pointed out that the integration of hydrology,ecology,geography and remote sensing which is representative by large spatial and temporal scale,high spatial resolution and high precision numerical simulation will become the main study topics.
