摘要:

利用1961—2018年内蒙古自治区119个气象站常规气象观测资料和1981—2018年11个农气站马铃薯生育期观测资料,采用逐级订正法,模拟分析马铃薯生育期气候生产潜力的时空变化特征,探讨马铃薯气候生产潜力对辐射、气温、降水变化的响应。结果表明:(1)内蒙古马铃薯生育期气候生产潜力多年平均为18 889 kg·hm-2,明显低于光合(32 095 kg·hm-2)和光温(30 829 kg·hm-2)两级生产潜力。(2)近58 a各级生产潜力均呈不显著减小趋势,且年际波动较大,其中气候生产潜力的年代际波动幅度更大,其变化与降水量变化存在显著正相关。(3)内蒙古马铃薯生育期光合生产潜力自西向东递减,光温生产潜力东西两侧低、中部高,而气候生产潜力高值区主要在中部偏南地区。(4)内蒙古大部地区马铃薯生育期气候生产潜力呈减小趋势,仅呼伦贝尔市中北部、兴安盟西北部、锡林郭勒盟东北部及赤峰市西部等地区为增大趋势。(5)辐射变化对马铃薯生育期气候生产潜力影响大部地区不明显。气温变化对马铃薯生育期气候生产潜力影响多为负效应,中西部大部地区和东南部地区负效应最为明显;正效应仅集中在呼伦贝尔市中北部、兴安盟西北部地区。内蒙古西部大部地区、呼和浩特市、赤峰市西部及兴安盟东部等地区降水变化对马铃薯生育期气候生产潜力的影响为正效应,而乌兰察布市南部、赤峰市东部和呼伦贝尔市西部和东部等地区为负效应。

Abstract:

Based on the conventional meteorological observation data at 119 weather stations of Inner Mongolia from 1961 to 2018 and the observation data during the growth period at 11 agro-meteorological stations from 1981 to 2018, the temporal and spatial variation characteristics of potato climatic production potential were simulated and analyzed by using step-by-step correction method, and the response of potato climatic production potential to radiation, temperature and precipitation changes were discussed. The results are as follows: (1) The average climatic production potential of potato during the growing period was 18 889 kg·hm-2 in Inner Mongolia, and it was significantly lower than photosynthetic production potential (32 095 kg·hm-2) and light-temperature production potential (30 829 kg·hm-2). (2) The production potential of potato with each level during the growing period decreased non-significantly in Inner Mongolia in the past 58 years, and their inter-annual fluctuations were large, while that of climatic production potential was the largest, it was significantly and positively correlated with precipitation change. (3) The photosynthetic production potential of potato decreased from west to east in Inner Mongolia, the light-temperature production potential of potato was low in eastern and western Inner Mongolia and high in the central, while the high value of climatic production potential of potato mainly appeared in the south-central area. (4) The climatic production potential of potato in most areas of Inner Mongolia decreased non-significantly from 1961 to 2018, while that in central and northern Hulunbuir, northwestern Xing’an League, northeastern Xilin Gol League and western Chifeng increased. (5) The effect of radiation change on climatic production potential of potato wasn’t obvious in most areas of Inner Mongolia. The impact of temperature change on climatic production potential of potato was negative in most areas, and the negative effect was the most obvious in most regions of the central and the west and southeastern Inner Mongolia, while the positive effect concentrated in north-central part of Hulunbuir and northwestern part of Xing’an League. The influence of precipitation change on climatic production potential of potato was positive in most areas of western Inner Mongolia, Hohhot, western part of Chifeng and eastern part of Xing’an League, while that in southern Ulanqab, eastern Chifeng and western and eastern Hulunbuir was negative.

Key words: potato, climatic production potential, simulation, Inner Mongolia Autonomous Region
