【摘要】：在RS技术支持下,应用气象数据(主要为气温、降水)、基础地理数据及2002—2011年时间序列的Landsat TM、ETM+、MODIS/Terra+Aqua MCD43A4遥感影像产品,对阿勒泰地区地表水资源时空变化特征进行了分析,探索气象因素影响下阿尔泰山冰川积雪和地表水资源之间的相互作用。结果表明:在研究时段内,阿尔泰山6月2日的冰川积雪面积呈波动增加趋势,8月21日的冰川积雪面积则呈波动减少趋势。从景观格局的特征来看,随着夏季冰雪融水量增加,水资源量总体呈上升趋势,在研究时段内水域总面积增加了57.91km2,增加面积主要来源于湖泊和水库,2011年的湖泊和水库面积分别为1 044.33km2和196.27km2,比2002年分别增加了16.67km2和101.79km2;沼泽湿地和坑塘湿地的面积变化呈一定的起伏,2002—2011年间面积分别减少了35.91km2和24.27km2,湖泊和水库的破碎度较低,沼泽湿地、河流和坑塘湿地的破碎度高,表明沼泽湿地、河流和坑塘湿地对气象因素变化较敏感。
[Abstract]:Under the support of RS technology, the application of meteorological data (such as temperature, precipitation), basic geographic data and from 2002 to 2011, the time series of Landsat TM, ETM+ MODIS/Terra+Aqua, MCD43A4 remote sensing images, the variation characteristics of surface water resources in Aletai area were analyzed, to explore the interaction between meteorological factors under the influence of Al snow and glacier in Taishan the surface water resources. The results showed that during the study period, Al Taishan June 2nd snow and ice area of increased volatility in August 21st, snow and ice area was decreasing trend. From the characteristics of landscape pattern, with the summer ice melt water to increase the amount of water resources, the overall upward trend in the study period, the total water area increased 57.91km2, increase the area mainly comes from lakes and reservoirs, lakes and reservoir area in 2011 were 1 044.33km2 and 196.27km2, 2002 16.67km2 and 101.79km2 were increased; the area change of marsh wetland and pond wetlands showed some ups and downs, 2002 to 2011 area were reduced by 35.91km2 and 24.27km2, the fragmentation of lakes and reservoirs is low, wetlands, rivers and ponds wetland fragmentation is high, that is sensitive to wetlands, rivers and ponds wetland the change of meteorological factors.
