- 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 10years were interpolated spatially with CoKriging meth-od, supported by ArcGIS Geostatistical Analyst software, using ground elevation and aspect assisted, while the averages ofmean error, mean standardized error and mean-root -square standardized error was 0.0024℃,0.0006 and 1.124 s, respective-ly .On the basis of 10-day period of air temperature surfaces interpolated and data relating to them, an spatial air temperaturedatabase based on geodatabase model hadbeenestablishedin order to lay a foundation to study air temperature change moni-toring , agricultural regionalization and crop yield estimation.
