Current changes in ecosystems Delta Ile due to the influence of natural factors and regulated flow

Abstract

Were represented results of a study the transformation of different ecosystems Delta Ili during 1979­2014 years. Based on the analysis of data on
the dynamics of the hydrological regime, changes in weather conditions and
studying satellite photographs over the past few decades, it was concluded
that determines the value of the conductivity p. Ile in the negative changes,
and environmental degradation in delta areas. The growth of water demand
in the Chinese and Kazakh part of the Ile­Balkhash basin drying and desertification caused on many hydromorphic delta ecosystems and reduced river
flows into Lake Balkhash. It is shown that a significant reduction in water
content of delta areas could drastically accelerate the degradation of arid
and hydromorphic ecosystems. Transformation processes delta ecosystems
while reducing runoff usually begin in the head and gradually spread to the
north and north­westerly direction towards the periphery of the delta. Most
clearly expressed in the desertification area drainage system Topar.
Key words: GIS technology, Ili­Balkhash basin, Ile delta, water content, the hydrological regime, the transformation of ecosystems.
