【Abstract】 This Paper introduces a self-designed equipment of Soil moisture dynamic variation. The equipment is less in investment, simple in observation, convenient in operation and numerous in testing items.The combined application can test many moistuer parameters and laws of soil moistuer dynamic variations.Meanwhele,it can tell soil moistuer conditions. Through the summary and analyses of observed data for years,the various moistuer contents tested are strongly systematic.Thei results are close to the years’ data of local Hydrology Station throuugh the correlation analysis and Comparasion.This has proved that the set of equipmentr is accurate and reliable。更多还原
