Environmental Assessment for Soil Cover of Urban Recreational Objects (Using the Example of Novosibirsk)

Abstract

In this paper has been presented an environmental assessment for the soil cover of Novosibirsk city’s one of the largest recreational objects — culture and recreation park “Zaeltsovsky”. Has been analyzed dynamics of such soil indicators as medium reaction (water and salt soil extracts), hydrolytic acidity, total absorbed bases, soil organic matter, solid residue of soil’s aqueous extract, dry matter’s mass fraction, moisture content and phytotoxicity. An analysis of above mentioned soil’s parameters dynamics has been carried out taking into account a digression stage for ecosystems in recreational facility’ territory. A negative correlation is observed between the ecosystem state and such soil indicators as amount of organic matter and moisture content. A positive correlation is observed between the ecosystem digression stage and soil phytotoxicity indicators. Revealed trends of changing in the soil’s physical-chemical and biological properties give an idea of the ecosystem digression relationship with the above mentioned indicators.
