| 摘 要： | 基于遥感技术，对内蒙古4个大型引黄灌区（河套灌区、黄河南岸灌区、镫口灌区、麻地壕灌区）近30 a的种植面积及种植结构的时空演变进行分析，并利用河套灌区7 a实测调查样本,对解译结果进行检验，确定遥感方法的可行性及精度。通过遥感解译得出，灌区的控制面积为17 845.55 km2，对比官方统计数据相差-1.73%。灌区种植面积及土地利用率近30 a来变化不明显，整体呈微增加趋势。近30 a灌区的种植结构发生了明显变化，由单一小麦种植结构演变成现今小麦、玉米、葵花的多元化种植结构。

| Abstract: | In this Paper, the remote sensing image information in recent 30 years was extracted and interpreted for 4 main irrigated areas (the Hetao Irrigated Area, South Yellow River Irrigated Area, Dengkou Irrigated Area and Madihao Irrigated Area) along the Yellow River in Inner Mongolia, and the spatiotemporal evolution of their planting area and planting structure was analyzed based on the remote sensing means. The measured samples of the Hetao Irrigated Area in 7 years were used to verify the interpreted results, interpretation accuracy and the feasibility of the remote sensing means. The remote sensing interpretation showed that the total control area of the 4 irrigated areas was 17 845.55 km2 and 1.73% smaller than that of the official statistic result. The planting area and land use rate of the 4 irrigated areas were changed insignificantly and in a very low increase trend in recent 30 years. The planting structure of the 4 irrigated areas, however, was changed significantly and evolved from the single wheat planting structure in the early years to the diversified planting structure of wheat, corn and sunflower afterwards in recent 30 years. |
