Современное развитие городов приводит к изменению сохранившейся на их территории частички природы, изучением которой занимаются на протяжении продолжительного времени. Анализ почв лесопарков города Екатеринбурга Свердловской области проводился на основе изучения морфологических и химических свойств почв. Почвенные разрезы были заложены в лесопарке им. Лесоводов России, в Юго-Западном, Санаторном, Уктусском и Шарташском лесопарках. В составе древостоя лесопарковой зоны Екатеринбурга преобладает сосна обыкновенная (Pinus sylvestris L.), отмечено отсутствие или неравномерное распределение подроста и подлеска. Чаще всего произрастают следующие подлесочные виды: ракитник русский (Суtlsus ruthenicus Fisch. ex Bess.), черемуха обыкновенная (Prunus padus L.), рябина обыкновен- ная (Sorbus aucuparia L.) и роза иглистая (Rosa acicularis Lindl.). В задачи исследования входило изуче- ние почв, на которых произрастают данные подлесочные виды. На бурых лесных почвах состав подлеска разнообразней, чем на дерново-подзолистых. В каждом лесопарке было заложено по 2–3 почвенных раз- реза и взяты образцы почв для определения агрохимических свойств каждого выделенного почвенного горизонта. Были определены скелетность, удельный вес, объемный вес, порозность, обменная кислотность рНКСl, обеспеченность доступными калием и фосфором, гидролитическая кислотность, сумма обменных оснований, емкость поглощения и степень насыщенности основаниями. В изученных лесопарках были выявлены два типа почв: бурые лесные и подзолистые. Бурые лесные почвы представлены двумя подтипами – типичными и оподзоленными, а подзолистые – дерново-подзолистыми. В почвах лесопарков не обнаружено горизонтов урбик, свойственных антропогенно преобразованным почвам, но отмечено присутствие антропогенных включений в поверхностных горизонтах. The modern development of cities leads to a change in the preserved, on their territory, pieces of nature, the study of which is engaged for a long time. The analysis of the soils of forest parks in the city of Yekaterinburg, Sverdlovsk region, was carried out on the basis of studying the morphological and chemical properties of the soils. Soil sections were laid in forest parks: Forest Park of Foresters of Russia, South-Western. Sanatorium, Uktussky and Shartashsky Forest Park. The stand of the Yekaterinburg forest park zone is dominated by scots Pinus sylvestris, and there is no or uneven distribution of undergrowth and undergrowth. The most common subshrub species are Cytisus ruthenicus, Prunus padus, Sorbus aucuparia, and Rosa acicularis. The objectives of the study were to study the soils on which these undergrowth species grow. On brown forest soils, the composition of the undergrowth is more diverse than on sod-podzolic soils. In each forest park, 2–3 soil sections were laid and soil samples were taken to determine the agrochemical properties of each selected soil horizon. Have been identifi ed skeletality, specifi c gravity, volume weight, porosity, pHKCl, К2О, Р2О5, Н, S, Е, V. In the studied forest parks, two types of soils were identifi ed: brown forest and podzolic. Brown forest soils are represented by two subtypes – typical and landslide, and podzolic – sod-podzolic. In the soils of forest parks, no urbic horizons characteristic of anthropogenically transformed soils were found, but the presence of anthropogenic inclusions in the surface horizons was noted.

The research work was conducted on eroded soil in the Keroua forest of Saida, Algeria, whose objective is to know the changes in the physicochemical and biological properties of forest soils subjected to the effect of water erosion. The samples were taken to a depth between 0-10 cm in each zone (eroded zone and control zone). Our results show that the biological properties are the most affected by water erosion where there was a significant decrease in basal respiration and microbial biomass, which had a negative influence on the metabolic quotient (higher values in the eroded area). For chemical properties, there was an increase in organic matter and total limestone, while the pHWater decreased in the eroded zone. For the physical properties. We raised a slight difference between the two areas, but which was not statistically significant.

AbstractNatural disturbances, such as forest fires, cause significant changes in the structure and functioning of semi-arid ecosystems. After such disturbances, the impact on the soil ecosystem in its entirety is misunderstood. In this study, two years after the last fire, changes in the physicochemical and biological properties of Aleppo pine forest soils in the semi-arid zone were observed. Among all physical properties analysed, only the soil moisture remained significantly lower in the burnt zone in contrast to control zone. Considering the chemical properties, the only negatively affected parameter is the rate of organic matter. In terms of biological properties, results showed that the fire caused a significant decrease in soil microorganisms by decreasing basal respiration and microbial biomass. Conversely, the metabolic quotient recorded higher values in the fire zone than in the control zone. These results indicate that microbial communities in semi-arid soils, already stressed by climatic hazards, are very sensitive to the passage of even low-intensity fires.
