额尔齐斯河流域1990-2010年湿地遥感监测分析
Remote sensing monitoring and analysis of wetland in Irish River Basin during the period from 1990 to 2010
摘要
Abstract
By means of the techniques of remote sensing and geographic information system, a spatial database for the wetland in Irtysh River Basin for the years of 1990, 2000, 2005, 2008 and 2010 is developed through the man-machine interactive interpretation approach based on its Landsat TM images of 1990, 2000 and 2010, CBERS-02 images of 2005 and 2008, database of environmental factors and field investigation data. The spatial database is analyzed. The variation characteristics of the wetland in Irtysh River Basin during the period from 1990 to 2010 are summarized. The results show that the area of the natural wetland has a fluctuating variation. Generally, the area of the natural wetland in 2010 is larger than that in 1990. The incremental area mainly comes from lakes, swamps and swamped grasslands, but the area of the valley forests and beaches has a gradual decreasing trend. The area of the artificial wetland has an obvious increase owing to the dramatic increase of the irrigated area, while the area of reservoirs and ponds has a fluctuating change and also has an increasing tendency.关键词
