随着地统计学方法的应用,土壤水分空间变异性研究不断深入。本文首先以地统计学方法指导土壤水分采样数和采样点的确定为出发点,论述了国内外基于地统计学的土壤水分空间变异性的研究现状,并指出了其存在的一些问题;然后,简述了GIS、遥感、神经网络、分形、无线传感器网络等技术和方法在土壤水分空间变异性研究中的研究现状、应用前景及面临的困难。
With the application of geostatistical methods, the research on spatial variability of soil moisture has been deepened. In this paper, we first use geostatistics to guide the determination of soil water samples and sampling points. The current research status of the spatial variability of soil moisture based on geostatistics both at home and abroad is discussed, and some existing problems are pointed out. Then, The research status quo, application prospect and difficulties in the research of spatial variability of soil moisture by GIS, RS, neural network, fractal and wireless sensor networks are described.
