A method for assessing the environmental-ameliorative state of irrigated lands includes measuring the parameters of environmental-ameliorative state in observation points at an irrigation plot as well as determining thereof in the laboratory conditions, contouring analytic maps, evaluating and formalizing the data of each of the indices, according to computer geographic information technology, in each of the nodes of settlement, contouring maps of the complex assessment of the state of the lands. In doing so an integrated approach and a score principle of criterion evaluations are used. Their essence lies in the use of complex hydrogeological, soil-ameliorative, geotechnical and environmental estimated parameters and ranking thereof according to the intensity and expressiveness with distribution into categories of the state. |
