本文采取遥感图像光学增强、地学分析和历史资料论证的方法,研究了太原断陷盆地古湖泊的演变与生态环境的变化。研究中应用了1973年12月11日,1977年5月9日和1979年10月23日三个年代的春、秋、冬季节的MSS5(+)与MSS7(-)的图像,并采用比值法提取信息,共选用了11个组合,提取了不同历史时期的古湖泊的轮廓界线,同时还应用光电扫描仪量算面积,进行定量分析。最后,结合历史资料,分析、确定了古湖泊的时代、森林植被的破坏及湖泊收缩乃至灭亡对环境的影响。
In this paper, the evolution of the ancient lakes in the Taiyuan fault depression basin and the change of the ecological environment are studied by means of optical enhancement of remote sensing images, geo-analysis and historical data verification. The images of MSS5 (+) and MSS7 (-) in the spring, autumn and winter seasons of the three generations of December 11, 1973, May 9, 1977 and October 23, 1979 were applied and the ratio Law extracted information, a total of 11 combinations were selected to extract the different historical periods of the ancient boundaries of the lake, but also the application of photoelectric scanner area, the quantitative analysis. Finally, combined with historical data, analysis and determination of the ancient lake era, the destruction of forest vegetation and the lake shrink or even the impact of the demise on the environment.
