摘要

保持地表径流和保持土壤水分是最重要的与水有关的生态系统服务。除了实地监测外,还设计了先进的遥感技术来揭示农业用地上的土壤水分动态。本研究比较了三个不同土地利用类型农区TWI和SAVI两种土壤水分指数。SAVI可以很好地反映气包带水分状况的空间变化。

Comparison of soil moisture indices and field measurements in hilly agricultural lands of SW Hungary
The retention of surface runoff and the preservation of soil moisture are among the most important water-related ecosystem services. In addition to field monitoring, advanced remote sensing techniques have been devised to reveal soil moisture dynamics on agricultural land. In our study we compare two soil moisture indices, TWI and SAVI, in three agricultural areas with different land use types. The SAVI has been found suitable to point out spatial variation on the moisture conditions of the vadose zone.
