摘要
利用兴安盟科右前旗农业气象观测站2010年～2022年逐日气象资料和水稻生育期观测资料,以温度、日照时数为影响因子,构建了以日为尺度的兴安盟水稻综合气候适宜度评价模型.首先结合兴安盟实际情况,对水稻温度和日照气候适宜度函数的参数进行修订,然后采用熵权法确定了二者的权重系数.最后使用该模型对科右前旗历年水稻从移栽至成熟期间的逐日气候适宜度进行了计算,同时计算出历年全生育期综合气候适宜度,并将水稻历年气象产量与全生育期综合气候适宜度进行相关分析.结果显示二者显著正相关,且在0.05置信水平上等级相关,表明该模型能够较好地反映出兴安盟气象条件对水稻生长状况的影响,可以用来评价兴安盟水稻生长的气候适宜度情况.
Abstract
Using the daily meteorological data and growth period observation data of Horqin Right Front Banner Agricultural Observation Station in Xingan League from 2010 to 2022,taking temperature and sunshine hours as influencing factors,an evaluation model of rice climate suitability in Xingan League on a daily scale was constructed.First,the parameters of rice temperature and sunshine climate suitability function were revised according to the actual situation of Xingan League,and then the weight coefficients of temperature and sunshine were determined by entropy weight method.Finally,the model was used to calculate the daily climate suitability of rice from transplanting to maturity over the years in Horqin Right Front Banner,and the whole growth period climate suitability were calculated.The correlation analysis between the comprehensive climate suitability of the whole growth period and the meteorological yield of rice over the years shows that they are significantly positive correlation,and the grade correlation is at the 0.05 confidence level.These shows that the model can better reflect the impact of meteorological conditions on rice growth in Xingan League,and can be used to evaluate the climate suitability of rice growth in Xingan League.
