摘要
本文用2014~2019年主要降雨过程基本雨量站数据,分500mDEM、1kmDEM、2kmDEM三种场景,将ANUSPLIN模型应用到江西省各地形代表区(山丘区:赣州市;丘陵区:吉安市;平原区:南昌市)降雨量插值中.结果显示,ANUSPLIN模型对江西省降雨量插值有较好的适应性,插值精度能达到良好及以上;在相同DEM分辨率的模拟场景下,ANUSPLIN模型降雨量插值精度排序为平原区>丘陵区>山丘区;1kmDEM场景较为适合江西省降雨量插值.
In this paper,the Anusplin model is applied to interpolate precipitation data in diferent terrain representative area(Mountain area:Ganzhou city;Hilly area:Ji'an city;Plain area:Nanchang city)according to precipitation data of main rainfall process from 2014 to 2019 under three scenarios of 500m dem,1km dem and 2km dem.Results show that the ANUSPLIN model is suitable for precipitation interpolation in Jiangxi province,and the interpolation accuracy can reach high level.In the same DEM Resolution simulation scenario,the descending order of precipitation interpolation accuracy of anusplin model is plain area,hilly area,mountain area.The 1 km resolution dem is more suitable for precipitation interpolation in Jiangxi province.
