塔里木河下游斑块类型动态变化遥感监测

Dynamic Remote Sensing Monitoring of Patch Pattern Change in Lower Reaches of Tarim River

研究以1959年、1973年、1989年、2000年和2008年航空和卫星遥感影像为数据源,结合地面调查,运用GIS技术、景观生态学原理和景观分析软件FARAGSTATS3.3,分析塔里木河下游断流段:断流前—断流期—输水后的这3个时间段近50年斑块类型景观格局变化。从斑块类型景观格局变化来定量评价各类型近50年变化动态,为丰富干旱区生态恢复研究理论和方法作出贡献。

By choosing aerial and satellite remote sensing data in the year of 1959,1973,1989,2000 and 2008 as the data source,combining with ground observation and using GIS technology,principles of landscape ecology and the landscape statistical software FRAGSTATS 3.3,the landscape pattern change before zero flow,during zero flow and after water supplement in the lower reaches of Tarim river during the late 50 years is analyzed and then a quantitative evaluation on the changes of each landscape pattern during the 50 years is conducted so as to enrich the theory and method of the study on the ecological restoration in the arid area.
