Phytotesting of the Soils of Urban Pedocomplexes in Residential Areas of Perm, Russia

Abstract

The response of watercress Lepidium sativum L. to the basic properties and toxicity of the soils has been established. When assessing the ecological state of the soil cover in residential areas of the city of Perm, the concept of the urban pedoсomplexes as combination of soil and man-made surface formations on the same soil-forming rocks within a certain functional zone was applied. The problem of choosing a test control was solved by using vermiculite with Knop solution as a root substrate. Phytotesting showed mainly satisfactory conditions of the upper layers of the soils in urban pedoсomplexes. At the same time, in the area of relatively old buildings, a trend towards the emergence of soil toxicity was revealed.

Ecological scales of indicator plants in an industrial region

“…Sampling points (survey sites) were set in such a way as to evenly represent the entire area of industrial Donbass with the centre in the city of Donetsk and large industrial facilities in the cities of Yenakiyevo, Makeevka, Gorlovka, Khartsyzsk. We used the methods of monitoring studies in urbanized areas [22,23]. The territories of the natural reserve fund were used as a control area (42 sampling points) for background monitoring in accordance with the general principles of ecological studies of landscape complexes and floristic observations [24,25].…”

Ecological phytomonitoring in Donbass using geoinformational analysis

“…Geodata are widely used to study and comprehensively control situations in technologically disturbed and urbanized areas [7,8].…”
