INTRODUCTION (abstract of PhD thesis)
The aim of the research is to assess the formation
of ameliorative regime
with depending on changes in the water-salt balance at current conditions of
irrigated areas of the Kashkadarya region where was
changed the ameliorative
condition under the influence of anthropogenic factors.
Object of the research work is irrigation massifs which located in irrigated
territories of Kashkadarya region.
The scientific novelty of the research is as follows:
the methods of assessing the efficiency of use of water and land resources of
the Kashkadarya Province in modern conditions has
been improved with taking
into account their shortage;
the assessment method of amelioration condition of irrigated fields has been
improved in the basis of the
water-salt balance equations;
the variability identification method of soil salinization and water – physic
properties in the irrigated areas of the Province has been improved in the basis of
mathematic statistical and hydro chemical calculations;
determining method for the length of the path of
formation of the required
concentration when mixing fresh and drainage water has been developed with
taking into account water
mineralization;
the assessment method of amelioration regime of irrigated fields has been
developed with taking into account water-salt regime and water ensure.
