| 摘 要： | 目前土壤属性的曲面建模面临两大问题,一是缺乏足够多的采样点进行模拟,二是采样点的土壤属性与环境变量间存在非线性关系.高精度曲面建模(HASM)方法在如何融合地学信息对土壤属性进行空间插值,尚需深入研究.本文提出高精度曲面建模与地学信息相结合的土壤属性空间插值方法(High accuracy surface modeli...

| Abstract: | There are two main limitations in surface modeling of soil property.One is the small number of available observations,and the other is the nonlinearity of the relationship between environmental variables and soil properties.It is still needed to research how high accuracy surface modeling(HASM)is combined with geographical information in soil property interpolation.This paper presented the method of HASM combined geographical information for soil property interpolation(HASM-SP).Based on types of soil,land u... |
