Оценка влияния лесонасаждений на обоснование гидролесомелиоративных мероприятий и качество водной среды на водосборном бассейне

Abstract

The purpose of the research is to assess the impact of forest reclamation plantations on the substantiation of the development of hydro meliorations and water resources for the river basin in the Nizhny Novgorod region. An assessment of the impact of afforestation of the territory on the substantiation of the development of hydro melioration on the catchments of the rivers of the Nizhny Novgorod region using the bioclimatic method of V.V. Shabanov under various scenarios of changes in agro climatic resources is carried out. When developing a scenario for changing agro-climatic characteristics, the research of Dokuchaev V.V. was taken as the bases. Development forecasts are based on substantiating the probability of the need for the development of hydro reclamation in different variants of afforestation of the catchment. Based on the results of the compilation of water management balances, an assessment was made of possible savings in water resources for irrigation and the impact of catchment afforestation on the quality of water in the river. An assessment of the effectiveness of water protection measures under different scenarios for the development of hydro reclamations and forest reclamations was carried out. According to the method of Kharitonov G.A., an assessment of the impact of catchment afforestation on the change in the underground supply of rivers was carried out. The following management methods are proposed: introduction of a water circulation system in the industry; wastewater treatment; reducing the risk of pollution from sewage from agricultural areas; water saving in irrigation.
