摘要
利用海南本岛18个国家气象观测站1981~2010的气象观测数据和站点地理信息资料,采用多元线性回归等方法建立海南热量、降水、光照、风速等气候要素的小网格推算模型,并利用部分区域自动站2009~2018年的观测数据对推算模型进行了检验和修正,在GIS技术支持下得到了海南气候资源小网格栅格数据及气候要素分布图。为进一步科学认识海南岛气候特点及分布规律,充分利用海南岛丰富的气候资源优势、克服不利气候因子的影响提供基础的理论支撑。
Based on the observational data of 18 national meteorological stations from 1981 to 2010 in Hainan Island and the geographic information of the observation stations,small-grid prediction models for calculating climate factors such as heat,precipitation,light and wind speed in Hainan Island were established by multiple linear regression.The prediction models established were verified and modified by using the observational data of some regional automatic observation stations from 2009 to 2018,and the small grid data of climate resources in Hainan Island and the distribution map were generated by using GIS.The results might help to further understand the climatic characteristics and distribution in Hainan Island,to take full advantage of the abundant climate resources and to overcome the influence of adverse climate factors.
