The firstquarter of the year covers planting of maize and single rice, and the growingperiod of winter wheat in southwest China. The season can generally becharacterized as somewhat below average. Between January and February, the cropcondition was average. From March, it dropped below average, possibly due tothe heavy rain during that period, and reverted to average again fromApril. The maximum VCI of 0.66 further confirms this result, although the CALFkept a stable level (+4%), in line with the agroclimatic indicators (RAIN,+36%;TEMP, -0.3°C; RADPAR, -8%).

本年的第一季度覆盖中国西南地区玉米和单季稻的种植季节以及冬小麦的生长季节，作物长势一定程度上低于平均水平。从1月至2月份，作物长势达到平均水平，从3月份伊始呈现下降态势，低于平均水平，很可能是由于该时段内降水过多导致，从4月份开始有恢复至平均水平迹象。尽管中国西南地区作物种植比例增长4%，基本保持稳定，但。农业气象指标中，降水偏多36%，气温偏低0.3°C，光合有效辐射偏低8%，最佳植被状态指数仅为0.66，进一步证明了上述长势水平。

Compared to the recent 5 year average,parts of North Chongqing and Northwest Hunan both show below average conditionin February and March with different levels from the spatial NDVI patterns andNDVI profiles. Compared to the recent average, a 47% increasing of rainfall inChongqing and 53% in Hunan have been monitored, which will probably have anegative effect on the local crops.

根据NDVI空间分布和过程线，与过去5年平均水平相比，重庆北部和湖南西北部部分地区的作物长势在2月和3月份不同程度地低于平均水平。就其降水而言，与近年平均水平相比，重庆偏高47%，湖南偏高53%，很可能对当地作物造成不利影响，需要持续监测。
