摘要

介绍了干旱半沙漠带盐渍土腐殖质物理性质和储量的动态变化。这项研究的基础是2010-2022年的观测数据。阿斯特拉罕地区典型的丘陵景观。铺设了100×100m的格栅。在采样层的网格节点处进行土壤研究。我们研究了荒漠化条件下盐渍土的物理性质(土壤水分、含盐量、土壤密度、过滤系数、土壤孔隙度、水分储量)、腐殖质储量和盐分状态的变化。对比分析表明,研究区发生了负面变化,可以说,土壤退化和荒漠化进程正在深入发展。已经确定,在0–40 cm的土层中,在最高空气和土壤表面温度增加的背景下,土壤水分储备显著减少,以及由于该地区的路堤而导致的水文状况变化。观察到除湿过程。草地独奏表现出最明显的负面趋势。由于筑堤,该地区水文状况的变化导致景观中自形土壤面积的增加和草甸土壤面积的减少。自同构带状土壤的盐度和压实度增加。贝尔丘陵的物理破坏加剧了这种条件下的退化和荒漠化发展过程。

Dynamics of physical properties of soils and humus reserves in salted soils under desertification
The dynamics of the physical properties and reserves of humus in saline soils of an arid semi-desert zone is presented. The basis for the research was observational data for 2010-2022. in a typical hilly landscape of the Astrakhan region. A grid of 100 × 100 m was laid. Soil studies were carried out at the grid nodes along the sampling layers. We studied the change in physical properties (soil moisture; salt content according to the amount of dense residue; soil density; filtration coefficient; soil porosity; moisture reserve), humus reserves and salt state of saline soils under desertification. Comparative analysis showed that negative changes have taken place in the study area and it can be stated that the processes of soil degradation and desertification are intensively developing. It has been established that in the soil layer of 0–40 cm there was a significant reduction in soil moisture reserves against the background of an increase in maximum air and soil surface temperatures, as well as changes in the hydrological regime because of the embankment of the territory. Dehumification processes are observed. The most clearly negative trend was revealed for meadow solonchaks. The change in the hydrological regime of the territory because of embankment contributes to an increase in the areas of automorphic soils in the landscape and a reduction in the areas of meadow soils. An increase in the degree of salinity and compaction was recorded for automorphic zonal soils. The physical destruction of the Baer's hills exacerbates the processes of degradation and the development of desertification in such conditions.
