Abstract:
The paper considers methodological approaches to assessment of biological and environmental
potential of landscape systems in the southern Kazakhstan soil-climatic conditions to the most complete and efficient
use of natural resources in the design and construction of high-performance agrolandscape systems. Based on
qualitative and quantitative indicators heat, light and moisture availability a mathematical model has been developed
to assess biological and environmental productivity of landscape systems including soil productivity and vegetation
cover.
It should be noted that the developed model of landscapes biological productivity assessment (Cbp) takes into
account the heat availability of the landscape systems soil cover (Ctb), natural moisturization coefficient of the
vegetation cover (Cm), and ecological productivity of landscapes (Cbp). This model is based on the potentially
available energy expended in soil-forming process (Qn) and natural moisturization coefficient of the vegetation cover
(Cm) is one of the modifications of the qualitative and quantitative models of natural system climatic productivity,
widely used in the field of geography and ecology assessment of natural system resources potential.
Based on the developed models of landscape systems biological and environmental productivity a comprehensive assessment of South Kazakhstan region natural resource potential was performed, including Almaty, Zhambyl,
Kyzylorda and Turkestan region using long-term data of 32 meteorological stations located on the territory of the
region.
Use of improved methodologies for assessment of landscape systems biological and ecological productivity can
more accurately determine the biological resources of the landscape systems according to agro-ecological areas and
to assess the efficiency of natural system natural resources potential.
