| 摘 要： | 应用陆地卫星TM资料和遥感图像处理ENVI3.2软件，以监督分类波谱角法、人机交互等方法提取冬小麦面积及分布信息。采用图像复合分类监测、比值（差值）图像监测、分类结果叠加监测和信息复合人机交互目视提取等方法研究了垦利县1987～1998年冬小麦播种面积及其空间分布的动态变化。结果显示，垦利县冬小麦播种面积呈不断增加的趋势，11年间共增加了11 264.5 hm2，其中从1992～1996年增加幅度较大。麦田面积的增加主要在垦利县中部和靠近黄河口的两侧地区，其减少则主要分布于西南和东北两个原小麦集中分布区。研究结果为该县冬小麦生产的管理及决策提供了科学依据。

| Abstract: | Using TM data and image process software ENVI3.2, the winter wheat area and distribution information were obtained by methods of Spectral Angle Mapper and man machine interactive interpretation etc. The dynamic changes of winter wheat area and its distribution between 1987 and 1998 at Kenli County were studied by the methods of images compound and classification, image ratioing, interactive visual interpretation and classification results overlay. The results showed that the winter wheat planting area of Kenli County increased by 11 264.5 hm2 in 11 years, which increased obviously from 1992 to 1996. The increased winter wheat area mainly distributed on the center and the places near Yellow River Outlet at Kenli County, the decreased area was mainly located on southwestern and northeastern parts, which were formerly the winter wheat main distribution areas. The results give scientific support for the management and decision making on winter wheat production of Kenli County. |
