摘要

在干旱地区,为动物提供饲料的方法之一是组织森林牧场,其生产力在很大程度上取决于天气条件。本研究分析了2018 - 2022年4 - 10月生长季节气象条件和热液系数(HTC)的变化及其对里海西北部沙质巴兹干块地天然牧场和森林复垦牧场的影响。牧草产量与气温呈负相关,与降水量呈正相关。建立了不同类型牧草热液系数(HTC)与生产力的关系,不同密度牧草下的决定系数R2为0.765,天然牧草下的决定系数R2为0.879。结果表明,在气候变化条件下,大气加湿是俄罗斯干旱区牧草稳定生产力的决定因素。

Relationship between hydrothermal coefficient (HTC) and productivity of pastures in the arid zone of Northwestern Caspian Sea
In the arid zone, one of the ways to provide animals with feed is the organization of forested pastures, the productivity of which largely depends on weather conditions. Our study analyzes changes in meteorological conditions and hydrothermal coefficient (HTC) during the growing season April-October from 2018 to 2022 and their impact, on natural and forest-reclaimed pastures of the sandy Bazhigan massif of Northwestern Caspian Sea. Pasture productively was negatively correlated with the temperature and positively correlated with the precipitation. The relationship between hydrothermal coefficient (HTC) and productivity of different types of pastures has been established with coefficient of determination of R2 of 0.765 under pasture with different density and R2 of 0.879 under natural pasture. Results showed that the atmospheric humidification is the determining factor of stable pasture productivity in the conditions of climate change in the arid zone of Russia.
