摘  要：
根据四川省南充市1960-2014年逐日气象数据,借助气候适宜度模型分析该市温度、光照、降水适宜度和气候适宜度的时空分布规律,并结合营山县一季稻产量资料,将气候适宜度划分为4个等级,最后对南充市一季稻的气候适宜性进行区划。结果表明,温度、降水适宜度未表现出明显的变化趋势,光照适宜度明显下降,气候适宜度在一定程度上下降但变化趋势系数不显著;气候适宜度与空壳率的相关系数为-0.603,通过了0.01水平显著性检验;研究区气候适宜度介于0.60~0.70,处于中适宜区和低适宜区,中适宜区主要集中在南充市东北部和西充县附近,其余地区为低适宜区。

摘  要：
Based on the daily meteorological data from 1960 to 2014 in Nanchong city, Sichuan province, climate suitability model was used to analyze the temporal and spatial variability of temperature, sunshine, precipitation suitability and climate suitability. Meanwhile, by using the rice yield data of Yingshan county, the climate suitability was divided into 4 levels.Finally, climate suitability regionalization of single-season rice was carried out in Nanchong city. The results showed, the temperature and precipitation suitability showed a no obvious trend while sunshine suitability presented a significant downward trend; Climate suitability showed a decreased trend but the trend coefficient was not significant. The correlation coefficient between climate suitability and the shell rate was-0.603, which passed the 0.01 level of significance test; Since climate suitability of study area were between 0.60 and 0.70, the whole study area were in middle climate suitability and low climate suitability. Middle suitability areas were mainly concentrated in northeast of Nanchong city and nearby Xichong county, and the rest of study areas were low climate suitability area.
