Studies have been carried out to identify trends in the transformation of the properties of saline and solonetzic soils in vineyards under changing regional weather conditions with intensive agricultural use. The tendency to increased aridity of the climate of the Anapa-Taman region against the background of alternating wet and dry periods was revealed. The previously noted increase in the average amount of summer precipitation and the average annual precipitation due to large deviations from the average values of the previous period led to the formation of a negative linear trend in the course of precipitation during the last 20 and 30 years. At the same time, a statistically significant increase in air temperature was observed in almost all cases. Changes in the soil properties of the key area with grape plantations under the influence of modern regional meteorological parameters were revealed. A comparative analysis of the structure of the soil profile demonstrated that there was a reduction in all studied soils of the amount of absorbed bases by 4–22%, primarily due to the decrease in exchangeable calcium, increasing the amount of salt by 5.8–149.2% compared to the study performed in 1982. The change in the salt composition was also revealed in soils: a decrease in the proportion of bicarbonates and an increase in the proportion of chlorides and sulfates were noted. The salt composition of southern deep solonetzic chernozems was most susceptible to change in the lower part of the soil profile, and southern medium-solonetzic chernozems mainly changed in the central part of the soil profile (at a depth of 120–130 cm). The revealed tendency to increased aridity of the climate of the Anapa-Taman region against the background of alternating wet and dry periods will contribute to the intensification of the processes of salt redistribution in saline and solonetzic soils under vineyards.

区域气象参数变化影响下盐碱地土壤的转化

摘要

已经进行了研究，以查明在不断变化的区域天气条件下，随着农业的大量使用，葡萄园中的盐分和松质土壤的特性发生了变化。在干湿交替的背景下，揭示了阿纳帕-塔曼地区气候干旱的趋势。先前指出的夏季降水量和年平均降水量的增加是由于与前一时期的平均值存在较大偏差，导致在过去20年和30年期间在降水过程中形成了负线性趋势。同时，几乎在所有情况下，观察到的空气温度都有统计学上的显着提高。揭示了在现代区域气象参数的影响下，葡萄人工种植关键地区土壤性质的变化。对土壤剖面结构的比较分析表明，所有研究过的土壤中吸收碱的量均减少了4–22％，这主要是由于可交换钙的减少，使盐量增加了5.8–149.2与1982年进行的研究相比，盐含量有所变化。土壤中的盐成分也有所变化：碳酸氢盐含量下降，氯化物和硫酸盐含量上升。南方深部黑钙质黑钙土的盐分最容易在土壤剖面的下部发生变化，南部中等松质黑钙质主要在土壤剖面的中部（深度为120-130 cm）发生变化。在干湿交替的背景下，阿纳帕-塔曼地区干旱加剧的趋势已显露出来，这将加剧盐分在葡萄园下的盐碱土和松土中的重新分配过程。
