以新疆冬小麦主要产区之一的伊宁县为例,从冬小麦生长季候性特征角度出发,结合Terra/MODIS这种新型的卫星传感器,通过建立植被指数ndvi变化时间序列,提取冬小麦种植面积;利用多元回归方法建立了NDVI植被指数与冬小麦产量间的估产模型。
Taking Yining County, one of the main winter wheat producing areas in Xinjiang, as an example, the winter wheat planting area was extracted by establishing a seasonal sequence of ndvi vegetation index from the perspective of winter wheat growth characteristics and using a new Terra / MODIS satellite sensor. A regression model was established to estimate the yield between NDVI vegetation index and winter wheat yield.
