| This study was based on experimental Zengcheng teaching and research base of South China Agricultural University. Soil water samples were designed and optimized for wireless sensor networks, for obtaining real -time and dynamic data of soil moisture. The paper analyzed spatial variability of soil moisture through combining GIS with geostatistics. The results showed that the moderate variability was in soil water and topography, elevation, vegetation and human activity had an evident effect on the soil moisture. |
