浙江省1：25万累年月平均极高气温特征值空间分布图（1971-2000年）

数据内容：以浙江省65个气象站1971到2000年累年平均数据、测站经纬度、高度,浙江省1：25万的DEM数据为基础,采用"多元回归+残差"的方法计算得到结果，然后可视化后的结果图。格式：ArcGIS栅格（Grid）格式。格网分辨率：250m。考虑经纬度和海拔高度等因素，建立最高温度的多元回归方程，再利用验证站计算最高温度残差，通过克里格插值方法对残差进行内插，将回归值加上残差分配值得到最终的最高温度栅格值。

Data Content: The visualization results were generated via calculations using the "multiple regression + residual" method, which is based on three types of datasets: 1) the annual average meteorological data from 65 meteorological stations in Zhejiang Province from 1971 to 2000, along with the longitude, latitude and elevation of each station; 2) the 1:250,000 DEM data of Zhejiang Province. The specific workflow is as follows: First, a multiple regression equation for maximum temperature was established by considering factors such as longitude, latitude and elevation. Next, the residuals of maximum temperature were calculated using validation stations, and then interpolated with the Kriging interpolation method. Finally, the final maximum temperature grid values were obtained by adding the regression values and the interpolated residual values. Format: ArcGIS Grid format. Grid resolution: 250m.
