摘要
应用CityStar地理信息系统和多元回归方法建立了偏关县温度、降水要素的小网格推算模型 ,运用这些模型计算了偏关县各网格点旬、月、年平均气温 ,以及月、年降水量的累年平均值和各级界限温度的初终日期、间隔日数和积温 ,效果良好。
The calculation models of temperature and precipitation on scale of 1km×1km grid based on City Star GIS and multiple regression were established in Pianguan county, Shanxi province. The mean temperatures of ten days, month and year; the monthly and yearly accumulated mean precipitations; and the starting and ending dates, interval days and accumulated temperature of each boundary temperature (0℃, 5℃, 10℃ and 15℃) were calculated by applying these models.
