| 摘 要： | 采用多时相陆地卫星TM数据，以分类后比较法和历史土地利用专题图支持下的目视检测方法进行黄河口耕地变化动态监测。建立了基于TM数字图像的耕地变化及其相关自然和人为因素变化的指标，对与耕地变化相关的自然环境要素变化及人为影响进行了分析。结果表明：从1987∽1998年，垦利县耕地增减变化较大，面积减少了5321．8hm^2，平均每年减少483．8hm^2。耕地的变化反映出该区土壤盐渍化的加重和水源的匮乏，以及人为不良活动的影响。在此基础上提出了该区生态环境安全的对策措施。

| Abstract: | Using digital satellite remote sensing TM data, the monitoring of cultivated land changes in the region of Yellow River mouth were carried out by methods of classification results overlay and land use map supported visual change detection. Indices of cultivated land change as well as its related natural and human-related factors were derived from TM data. Correspondent natural environment factors and human influences were analyzed accordingly. Results show that obvious change in cultivated land occurred in Kenli County, which decreased by (5 321.8) hm~2 from 1987 to 1998, i.e. 483.8 hm~2 every year. These changes indicated the aggravation of soil salinization, and the influence of adverse human activities. The countermeasures of ecological environment security of the study area were proposed. |
