以ArcGIS地理信息系统为支撑,气象站点观测的1997～2006年的旬平均气温为插值变量,采用径向基函数(Radial Basis Function)方法,对黑龙江省旬平均气温进行空间插值.结果表明,拟合出全省1 km×1km单元的各旬平均气温表面数据.36个旬插值结果的均误差、均方根误差的平均数分别为0.0562和0.765℃.根据插值结果分别计算全省≥0℃和≥10℃旬、月和年积温表面.研究结果为气温变化监测、农业区划、土地生产潜力计算和千亿斤粮食背景下作物估产等研究工作奠定基础.

A total of 36 10-day air temperature was interpolated spatially to obtain air temperature surface in 1 km × 1 km square in Heilongjiang Province with Radial Basis Function method, supported by ArcGIS software, adopting 10 years of 10-day air temperature during 1997-2006 from weather stations as interpolation variables. Cross-validation results showed that the average of mean, root-mean-square errors were 0.0562 and 0.765 ℃, respectively. By the use of interpolation results of the average 10-day air temperature, the active accumulated temperature of 10-day, monthly and yearly period had been worked out to show spatiotemporal variation by which spatiotemporal variation of air temperature had been analyzed in order to lay a foundation to study air temperature change monitoring, land capability evaluation, agricultural regionalization and crop yield estimation.
