| 摘 要： | ［目的］研究康平县热量资源变化趋势，为农业可持续发展提供气候依据。［方法］应用最小二乘法进行线性拟合及Excel程序，分析热量资源趋势变化及差异。［结果］在近50年里，平均气温升高1.6 ℃，∑T≥0 ℃积温增加了315 ℃，∑T≥10 ℃积温增加了280 ℃。50年经历3个温度“拐点”，从1989年后温度上升趋势明显。冬半年气温升高幅度较大，夏半年气温升高较缓。［结论］热量条件的改变，农业结构需要重新整合，“陈旧的农业气象指标”需要重新确认研究，才能适应农业的可持续发展。 |

| Abstract: | Objective]To study the trend of Kangping County Change heat resources for sustainable agricultural development based on the provision of climate.Method] The linear least squares fitting and Escel procedures, changes of heat resource trends and differences were analyzed.Result] The average temperature raised 1.6℃, ΣT ≥ 0℃ accumulated temperature increased 315℃, ΣT ≥ 10℃ accumulated temperature increased 280℃ in recent 50 years.Through the three "inflection point", temperature upward trend became significant from 1989.Temperature range was larger when in winter, more moderate in summer.Conclusion] The changes in heat conditions, required the new integration of the agricultural structure,"the old agro-meteorological indicators"confirmed needing new research to adapt to the sustainable development of agriculture. |
