【摘要】：針對傳統(tǒng)的農(nóng)田灌溉面積提取方法單一且費時費力的問題,提出基于遙感地表溫度反演及植被供水指數(shù)(VSWI)的方法對石津灌區(qū)農(nóng)作物的灌溉面積進行了提取。在利用Landsat 8影像提取灌溉面積的同時通過高分1號影像提取的小麥種植結(jié)構(gòu)對灌溉區(qū)域進行了約束,從而減少了其它地物對灌溉面積提取的影響。結(jié)果顯示,兩種方法計算得到的灌溉區(qū)域重疊率達87%,同時將利用遙感方法提取的灌溉結(jié)果與實地調(diào)查的結(jié)果相比較,發(fā)現(xiàn)在灌溉時間和面積上具有較好的一致性,因此認為所得結(jié)果較為可靠。該方法不僅可以快速、高效的獲取到較高精度的灌溉面積數(shù)據(jù),同時大大減少了外業(yè)工作量,因此可以為農(nóng)業(yè)灌溉區(qū)域的調(diào)查和監(jiān)測提供有效的技術(shù)支撐。
[Abstract]:In order to solve the problem that the traditional method of farmland irrigation area extraction is simple and time-consuming, a method based on remote sensing surface temperature inversion and vegetation water supply index (VSWI) is proposed to extract the irrigated area of crops in Shijin irrigation area. The irrigated area was extracted by Landsat 8 image and the wheat planting structure extracted from the high score 1 image was used to restrict the irrigated area, thus reducing the influence of other ground objects on the irrigation area extraction. The results showed that the overlap rate of irrigation area calculated by the two methods was 87%, and the irrigation results obtained by remote sensing method were compared with the results of field investigation. It was found that the irrigation time and area were in good agreement with each other. It is considered that the results obtained are more reliable. This method can not only obtain high precision data of irrigation area quickly and efficiently, but also greatly reduce the workload of field operation, so it can provide effective technical support for the investigation and monitoring of agricultural irrigation area.
