摘要
介绍了聊城市冬小麦面积遥感提取研究的意义、背景、方法,阐述了研究思路和技术路线,得到了聊城市冬小麦面积遥感提取的分类结果,计算出了冬小麦种植面积,并对其进行了精度评价,指出聊城市各县(市、区)冬小麦面积都在不同程度地减少,提出应当采取措施保护耕地面积、调动农民种粮的积极性,确保该地区粮食产量的增长,该研究对粮食生产和粮食安全具有非常重要的意义。
In this paper, the author introduced the significance, background and method of remote sensing extraction of winter wheat area in Liaocheng City, and expounded the research ideas and technical routes. On above foundations, the authors obtained the classification results of remote sensing extraction of winter wheat area in Liaocheng City, and calculated planting area of winter wheat. Then, the author evaluated its accuracy, and pointed out that the area of winter wheat in counties（cities,districts） of Liaocheng City has been reduced to varying degrees. The author proposed that measures should be taken to protect the area of cultivated land, mobilize the enthusiasm of farmers to grow grain and ensure the growth of grain yield in this region. This study has significant meaning on food production and safety.
