In Huanghuaihai,the main crop—winter wheat—will be harvested in two months. As shown by theNDVI development graph, crop condition was generally below the five-year average during the monitoring period and worse than the previous year. The overall situation, however, appears to be good in most of the region, as shownby the spatial NDVI patterns; crop condition was above average in almost the entire region except for northern Tianjin, southern Hebei, eastern Shandong,and northern Jiangsu. Besides, parts of Henan and Shandong were above average in January but deteriorated in February. Satisfactory crop condition can be also inferred from the prevailing agroclimatic conditions in Huanghuaihai: 23 percent above average rainfall, 0.5°C above average temperature, and 1 percent above average PAR, resulting in a large improvement in the biomass productionpotential (35 percent). The maximum VCI presents high values in eastern Hebeiand northern Shandong, while low values occur in central and eastern Henan.Overall, favorable climatic conditions will greatly benefit the development of winter wheat and the sowing of the next season crop.

在黄淮海区域，主要作物冬小麦将在两个月内收获。NDVI过程线显示，该区域的作物长势总体上低于近五年平均水平，且相比去年较差。然而，NDVI距平聚类及其相应过程线显示，作物总体长势在大部分区域来看显示较好。除天津北部、河北南部、山东东部和江苏北部外，其余地区的作物长势均位于平均水平之上。此外，河南部分地区以及山东作物长势在1月份时位于平均水平之上，在2月份开始下降。这种良好的作物长势同样体现在黄淮海区域的农气条件上：降水较平均水平增加23%，温度高于平均水平0.5°C，光合有效辐射较平均水平增加1%，这些因素直接导致潜在生物量大幅增加（35%）。植被状态指数最大值出现在河南中部和东部地区。总体来说，良好的气候条件将十分有利于冬小麦的生长，衣有利于下一季作物的播种。
