内蒙古兴安盟玉米气候适宜度模型构建

CLIMATE SUITABILITY MODEL FOR MAIZE IN XINGAN MENG OF INNER MONGOLIA

本文结合兴安盟实际情况,对温度、降水和日照适宜度函数的参数及权重进行修订,利用突泉县农业观测站1982~2015年逐日气象资料及同期的玉米单产和生育期观测资料,建立了以日为尺度的兴安盟玉米气候适宜度模型。使用该模型对历年突泉县玉米从播种至成熟期间的逐日气候适宜度进行了计算,同时计算出各生育期的综合气候适宜度以及全生育期综合气候适宜度,并将全生育期综合气候适宜度与历年气象产量进行了相关分析,得出二者显著正相关,且在0.01置信水平上等级相关,表明该模型能够较好的反映出兴安盟气象条件对玉米生长状况的影响,可以用来评价兴安盟玉米生长的气候适宜度情况。

In this paper, the parameters and weights of temperature, precipitation and sunshine suitability function are revised, combined with the actual situation of Xingan Meng. Using Xinan Meng Tuquan County Agricultural observation station1982 - 2015 years of dailymeteorological data and maize yield of the same period and growth stageobservation data, established on a daily scale Xin- gan Meng maize climate suitability model. Using the model, the daily climate suitability of maize from sowing to mature of the Tuquan county is calculated. At the same time, the comprehensive climatic suitability of different growth stage were calculated. Through the correlation analysis between climate suitability in the whole growth stage of maize and relative meteorology yield, obtained significant positive correlation, and they are also level correlation at 0.01 confidence level. These shows that the model can reflect the influence of Xingan Meng meteorological conditions on the growth of maizebetter and can be used to evaluate the climate suitability of maize growth in Xingan Meng.
