Cuts were made in the soil of the area to determine the negative impact on the soil cover caused by the construction on 10 hectares of the Ar Zaisan area of Bogdhan Mountain and to estimate the amount of damage to the soil. Soil physics and chemistry feature quality specific year focus by indicator Areas of the same typology that have been fenced for more than 10 years  soil feature quality in comparison study wax. According to the research results, the content of humus in the soil of the area decreased by 2.3%, the content of mobile phosphorus and potassium as nutrient elements decreased by 61.1-83.3%, the content of physical clay decreased by 78.8%, the salt content decreased by 1.55%, the volume weight or density increased by 18.1% and sand content increased by 65.5%. Based on this, it is reasonable to believe that the properties of the soil in the built-up area have deteriorated significantly.
