欧洲中部与俄罗斯西部主产区Crop and environmental conditions in major production zones

Authors: 超级管理员 | Edit: Miao

欧洲中部与俄罗斯西部大部分地区的冬季作物和夏季作物长势良好,最佳植被状态指数达到0.94。主产区在监测期内的农业气象条件对作物生长有利,降水较多年平均水平增加了11%,温度微增0.1℃。光合有效辐射较平均水平偏低了1%。

降水距平聚类空间分布与过程线结果显示,俄罗斯西南部和乌克兰东北部从2月起降水量高于多年平均水平,在5月份降水达到峰值。除了主产区西南部包括罗马尼亚和乌克兰南部等地区,主产区的大部分地区从6月开始降水处于平均水平或低于平均水平。整个主产区在2月经历了高温天气,俄罗斯东部地区温度较平均水平偏高达7℃,然而,大部分地区的温度从4月开始逐渐降至平均水平,波兰在4月中旬温度较平均水平偏低5℃。

本监测期内,主产区内的耕地种植比例高达100%。受东南部地区良好的水分条件影响,该地区大部分像元的最佳植被状态指数均大于1,同时潜在累积生物量较近5年平均水平偏高20%以上,使得整个主产区的生物量水平显著增长,增幅达到12%。


During the current monitoring period, most parts of the Central Europe to Western Russia MPZ presented favorable conditions of winter and summer crop (average VCIx=0.94). The agroclimatic indicators showed favorable condition for crop growing, with a 11% increase of rainfall and a slight 0.1°C increase of temperature compared with the average, while RADPAR was slightly below average by 1%.

As indicated by the rainfall profile analysis, the west and south of Russia and northeastern Ukraine received well above average rainfall since February, with significant rainfall peaks in May. Most regions of the MPZ presented average or below average moisture conditions from June except the southwestern part, including Romania and most parts of south Ukraine. Temperature profiles showed correlated variations among most countries of the MPZ. The whole region experienced high temperatures in February (as much as 7°C above average in the east part in Russia). However, temperature dropped to average from April, with more than 5°C below average in across Poland in mid-April.

Almost all of the arable land was actually cropped during the reporting period. Due to the favorable moisture condition in the southeastern part of the MPZ, the accumulated potential biomass (BIOMSS) is much above the five-year average (>20%), and many pixels’ maximum VCI value were greater than 1 in this region; correspondingly, the BIOMSS of the whole MPZ shows a significant increase of 12%.
