高精度的空间化降水信息对于区域水资源管理、生态环境治理、作物适宜性评价等方面都具有重要意义.选取浙江省72个气象站点1971 - 2008年38年的年平均降水量资料,在地统计学和地理信息系统(GIS)支持下,结合了坡度、坡向、到海岸线距离、周围10 km范围内的平均海拔高度和周围10 km范围内的最高海拔高度等地形地理因素,采用回归逆距离权重插值法、回归克里金插值法、回归样条插值法和回归趋势面插值法等多种插值方法对研究区年降水量的空间分布进行了插值研究,通过10个检验站点的插值误差来分析不同插值方法,并对模拟的年降水量空间分布图进行了比较分析.结果表明：回归逆距离权重插值法误差最小,效果最好.
