Reservoir watershed ecological protection method

Abstract

The invention discloses a reservoir watershed ecological protection method, which comprises the following steps of building a reservoir watershed digital geographic information system and performing unit division; building a contaminant database of villages and towns, popularization, livestock breeding, industrial and mining enterprises and the like; building a distributive rainfall runoff and contaminant moving coupling model; analyzing the moving rule of contaminants between the units. The method provided by the invention can be used for diagnosing the reservoir watershed ecological safety problem, analyzing the reservoir major contaminant resources and time-space distribution features, and water environment evolution processes. The surface source pollution control is implemented from the source; the ideal water quality standard reaching of reservoir entering water quality is realized through river ecological measures and watershed tail end estuarine wetland management measures. The method provided by the invention has the important technical support effect on reservoir water resource protection, beautiful village building and watershed ecological environment restoration.

Description

technical field [0001] The invention relates to the field of ecological environment protection of water sources, in particular to a method for ecological protection of reservoir basins. Background technique [0002] In recent years, with the continuous increase of the population in the reservoir basin, that is, the water source area, the continuous acceleration of the urbanization of the rural population, and the continuous development of agriculture and animal husbandry in the basin, the per capita pollutant discharge in the basin and the discharge of various agricultural and animal husbandry pollutants A large amount of pesticides, chemical fertilizers, livestock manure, garbage, industrial and mining pollutants, etc. have entered the reservoir area, resulting in the deteriorating water quality of the reservoir, the eutrophication of the water body is becoming more and more serious, and even the outbreak of algal blooms, which seriously affects the water supply safety of th...
