摘要：以磴口县1990年和2003年2期秋季相TM遥感影像为基础数据,采用遥感影像解译与地面调查相结合办法,对磴口县13 a沙荒土地农业综合开发过程中的土地景观变化状况进行了监测。根据磴口县的土地沙漠化和土地覆盖的特点,采用遥感影像监督分类方法获得监测区2个时期的土地利用图,通过野外考察和抽样调查,对分类结果进行了验证。监测结果显示,13 a中,由于开荒和水资源的不合理利用等,磴口县的沙漠化仍在发展之中。结合同期的气象和统计资料,对土地利用变化产生的环境影响进行了分析评价,提出了可持续发展对策。
Taking advantage of the methods of combination interpretation of TM Imagery with on-the-spot investigation,Double date Remote sensing TM Imagery of Denkou in 1990 and 2003 were interpreted.The Monitoring for land utilization types and cultivated land dynamic changes during Agriculture Synthetical Development of sandy waste land was performed in recent 13 years in Denkou County.According to the desertification and land cover characteristics,two land use maps were draw by the methods of Remote sensing image supervised classification.On the basis of their changes and environment effects and interrelated information,the reclamation results of sandy waste land were analyzed and evaluated.The Sustainable strategies and measures,which were suitable for utilization sandy waste land,were put forward to local area.
