基于ArcGIS的近10年黑龙江省旬平均气温插值与建库
The Spatial Interpolation and GeoDatabase Foundation of Average 10-day Air Temperature of Heilongjiang Province in Recent 10 Years Based on ArcGIS
【摘要】 以ArcGIS Geostatictical Analyst为支撑,利用高程、坡向数据作为辅助,采用协同克里格(Cokriging)方法,对黑龙江省近10年旬平均气温进行空间插值,36个旬平均气温插值结果均误差、平均标准差和均方根标准差的平均值分别为0.0024℃、0.0006和1.124。基于全部旬平均气温插值结果及其相关数据,建立旬平均气温Geodatabase空间数据库,为气温变化监测、农业区划和实现千亿斤粮食的作物估产等研究奠定基础。
【Abstract】 All of 10-day period of average air temperature in recent 10 years were interpolated spatially with CoKriging method,supported by ArcGIS Geostatistical Analyst software,using ground elevation and aspect assisted,while the averages of mean error,mean standardized error and mean-root-square standardized error was 0.0024℃,0.0006 and 1.124 s,respectively.On the basis of 10-day period of air temperature surfaces interpolated and data relating to them,an spatial air temperature database based on geodatabase model had been established in order to lay a foundation to study air temperature change monitoring,agricultural regionalization and crop yield estimation.
