摘要: 目的】评估新疆棉花障碍型冷害精细化风险,为新疆棉花种植业规避冷害提供科学依据。【方法】以1951~2015年新疆66个农业气象站点逐日数据为基础,利用并分析MODLT1M中国1KM地表温度月合成产品2000~2016年每年9月LTN AVG数据资料,以日平均气温连续3 d≤20oC为棉花障碍型冷害判定指标。根据已有的冷害风险评估指标概念模型,计算冷害强度与频率分指标。通过将次冷害强度和次冷害频率升尺度为年冷害强度和冷害年频率构建综合冷害风险指标,将原本松散的冷害频率和强度关系突显出来,依据二者之间的稳定函数关系,确定冷害年频率等级来对应冷害年强度等级,划分冷害风险指标各临界阈值。以地理因子归一化加合趋势面+温度趋势面校正的方法,准确推算新疆棉花冷害风险指标。紧密结合风险等级划分与风险指标推算结果,评估新疆棉花冷害风险。【结果】新疆棉花障碍型冷害发生风险北疆高于南疆和东疆,北疆西部沿天山一带棉花种植区冷害风险自西向东逐渐增加。模型模拟冷害风险指标值与站点实测计算值之间无明显差异,两者散点图线性拟合R2为0.97,结果准确。【结论】研究构建的评估方法能够实现对新疆棉花障碍型冷害风险的客观评价,所构建的方法论不仅适用于棉花,还可适用于其他作物冷害的风险评估。

Abstract: Objective】 To realize the fine risk assessment of obstacle chilling injury of cotton in Xinjiang in the hope of providing scientific basis for avoiding chilling injury of cotton in Xinjiang.【Method】 Based on the daily data of 66 agricultural meteorological stations in Xinjiang from 1951 to 2015, the LTN AVG data of MODLT1M China 1KM surface temperature synthetic products from 2000 to 2016 were analyzed and used, and the daily average temperature ≤20℃ for 3 consecutive days was used as the determination index of cotton obstacle chilling injury. Based on the existing conceptual model of chilling injury risk assessment index, the indices of chilling injury intensity and frequency were calculated. By increasing the intensity and frequency of secondary chilling damage to the annual chilling damage intensity and the annual frequency of chilling damage, the comprehensive cold damage risk index was constructed, and the relationship between the original loose chilling damage frequency and intensity was highlighted on the basis of the stability of the function relation between the two. By determining the annual frequency grade of cold damage to correspond to the intensity grade of cold damage year, the objective division of each critical threshold of cold damage risk index was realized. By using the method of geographic factor normalization plus trend surface and temperature trend surface correction, the risk index of cotton chilling injury in Xinjiang was calculated accurately. The risk grade classification and risk index calculation results were closely combined to realize the risk assessment of cotton chilling injury in Xinjiang.【Result】 The risk of obstructed chilling injury of cotton in Xinjiang was higher in northern Xinjiang than in southern Xinjiang and eastern Xinjiang, and increased gradually in western Xinjiang along the Tangshan Mountains. The results proved that there was no significant difference between the model simulation chilling injury risk index value and the measured calculated value of the site, and the linear fitting R2 of the scatter diagram of the two was 0.97, so the research results were accurate. 【Conclusion】 The evaluation method constructed in this study can achieve objective evaluation of the risk of obstacle type chilling injury of cotton in Xinjiang, and the methodology constructed is applicable not only to cotton, but also to other crops' risk assessment of chilling injury.
