Abstract

Present-day changes in the landscape structure of the Don Basin are analyzed. Data of water-balance stations are used to determine the contributions of various land types to the formation of spring surface flow. Estimates are given for the present-day anthropogenic and climatic changes in the surface flow and infiltration into soil in plowed lands during spring flood, as well as river flow and its surface and subsurface components. A characteristic formation feature of the annual water balance is shown to be a considerable decrease in the surface flow component along with an increase in its subsurface component. The identified trends in the current changes in the runoff from the Don watershed are stable and have to be taken into account in the forecasting of water resources for the nearest future.

唐盆地的景观水文变化

摘要

分析了唐盆地的当今景观变化。水平衡站的数据用于确定各种类型的土地对春季地表水流形成的贡献。对春季洪水期间地表流和耕地中土壤的人为和气候变化以及河水及其表面和地下成分的当今人为和气候变化进行了估算。年度水平衡的一个特征性形成特征是地表水分量显着减少，而其地下分量增加。顿河流域径流当前变化的确定趋势是稳定的，在最近的水资源预测中必须考虑到这一趋势。
