| 摘要: |
| 利用2001年12月28日、2002年3月18日、7月24日、9月26日、12月15日五期ETM+遥感影像, 提取了巴丹吉林沙漠湖泊年内季节变化信息, 并分析了湖泊季节变化的统计特征与空间分布特征.结果显示, 巴丹吉林沙漠湖泊总面积和数量随季节更替呈现出明显的统计特征与空间分布特征.湖泊总面积和数量在当年春、夏、秋、冬季均依次减少, 到第二年春季又逐渐恢复到前一年春季状态;湖泊面积季节变化萎缩与增大区域呈集聚、连片分布态势, 部分时段湖泊面积变化表现出渐变分布特征.研究结果可为进一步深入研究巴丹吉林沙漠湖泊水循环、湖泊水量平衡、湖泊生态系统提供科学参考。 |

| Abstract: |
| Using ETM+ remote sensing images acquired on Dec.28 in 2001, March 18, July 24, Sept.26, Dec.15 in 2002, re-spectively,this study extracted the information of seasonal changes of the number and areas of lakes and analyzed the statistical char-acteristics and spatial distribution of them.The following conclusions were drawn.Firstly,the number and total area of desert lakes showed a decreasing trend from spring, summer, autumn to winter in the first year and regained the original condition gradually in the next spring.Secondly,the seasonal variation of lake area displayed an obvious characteristic that the atrophic and increased area of lake present a distribution of gathers and continual pieces and gradual changes in the spatial distribution showed in some time section.The automatic weather observation station of Badain Jaran Desert had been completed in winter in 2009.Our next focus is to study the scientific issues of lake water cycle further,water balance both using RS imagery data and meteorological observation data. |
