Continuous grazing is a factor that impacts on the spatial distribution and weakens the spatial heterogeneity of soil moisture and salt content in saline grassland.

持续放牧已经成为一种稳定影响盐化草场水盐空间分布的结构性因素，使盐化草场的水盐空间异质性减弱。

The study on the distribution of soil moisture provides scientific foundation for variable irrigation in a field.

田间土壤墒情分布特性的研究，为田间精量灌溉提供了科学依据。

It also carries the risk of producing an inaccurate picture of the overall distribution of moisture, as the spots chosen for sampling may be considerably damper or drier than the soil just a few metres away.
