- Аннотация: А quantitative and detailed information on spatially distributed physical properties of soils is required in the design of land reclamation activities, the organization of the territory and other soil-engineering projects. In particular, in the design and construction of drainage systems, information is needed on the spatial distribution of the projected area of hydraulic conductivity over the area; in the organization of irrigation systems, spatial distributions of the properties of water retention of soils, with precise farming, the distribution of agrochemical properties, etc. Taking into account that the properties of soils vary enormously in space, a method of calculating the desired soil properties (filtration coefficient, water retention, thermal diffusivity, etc.) by simple easily determined parameters of the parameters of soils, so that subsequently, using the easily identifiable spatially distributed property, calculate the necessary hydrological parameters of the soil cover and create the required physical property, hydrology or temperature regime of the soil cover necessary for the production of the GIS map project. This method is pedotransfer functions, which allow for fairly easy properties to statistically justify the spatial distribution of the required property. Examples of calculation and use of pedotransfer functions are given.
