摘要
随着社会经济的发展,城市用地向外扩张,农用地受到直接影响,面积不断缩减。随着遥感技术日趋成熟,可通过遥感技术获取的影像图片来分析农用地的面积形态。以达州市农用地的缩减为例,引入缩减强度指标,分析和总结了达州市农用地的缩减规律及特征。
With the development of the economy and urban land expansion,agricultural land's area is shrinking.Due to the mature of remote sensing technology,we can use the images acquired by remote sensing technology to analysis the area form of agricultural land,Taking agricultural land shrinking in Dazhou City for example,we introduced the strength index,and analyzed and summed the shrinking rule and characteristics of agricultural land in Dazhou City.
