摘要:
通过对遥感数据进行分析，采用非监督分类法对影像进行分类，最终得到灌区土地分类及耕地种植结构。利用高分辨率IKONOS影像对分类结果进行精度评估，证明TM影像应用于灌区尺度土地利用分类具有较高的精度，能有效克服人为因素的影响，较为准确地提取灌区耕地种植面积及其空间分布。利用SEBAL模型对蒸散发进行反演，反演结果与实测值误差在允许范围内。研究结果可为河套灌区用水量研究提供新的方法。
Abstract:
Based on the analysis of romote sensing data, used non-supervised classification to classify the image, and at last the land classification and crop planting structure were determined. High-resolution IKONOS was used to assess the accuracy of image classification results.It proved that TM image had high accuracy for the land-use classification on the irrigation district scale. The results showed that it could effectively overcome the impact of human factors. Crop acreage and its space distribution could be extracted more accurately. The SEBAL model was used to invert evapotranspiration. The inversion results were closed to the measured values. This study provides a new method for the research of water consumption in Hetao irrigation district.
