Abstract

The article presents the results of engineering and geoecological studies of the salinity of the soils of the city of Nukus to the ground water level. The results of observations of changes in the city’s ground water level are presented. It was found that the increase of the water level leads to additional salinization of the soils, which worsens the ecological situation of the city, has a negative impact on green spaces and reduces the longevity of plants. According to the results of research, maps-schemes of salinization of the city’s soil were compiled. Studies have shown that the soils of the territory of Nukus are saline and mainly belong to the chlorine-sulphate type of salinity.

Highlights

The city of Nukus is located in the southern part of Karakalpakstan (Uzbekistan), on the right bank of the Amu Darya, 800 km northwest of Tashkent (1255 km by road)
This circumstance indicates an increase in the aggressiveness of underground water, which in turn contributes to the suppression of green spaces
It should be noted that salt-tolerant plants lead to a decrease in soil salinity

Summary

Introduction

The city of Nukus is located in the southern part of Karakalpakstan (Uzbekistan), on the right bank of the Amu Darya, 800 km northwest of Tashkent (1255 km by road).The southern and eastern parts of the city are surrounded by the Kyzylkum desert. The city of Nukus is located in the southern part of Karakalpakstan (Uzbekistan), on the right bank of the Amu Darya, 800 km northwest of Tashkent (1255 km by road). One of the ecological features of the city of Nukus is the salinity of the soil. The results of the studies show that there is an increase in the salinity of the soil. Studies show that due to increased salinity in Karakalpakstan, the longevity of woody and shrubby plants decreases and the ecological balance is disturbed. This is observed throughout the entire territory of Karakalpakstan [1,2]
