Embodiment Construction

[0028] The specific implementation of the present invention will be described in detail below in combination with specific situations.

[0029] Depend on Figure 1-3 Shown, the present invention in concrete implementation, comprises the following steps:

[0030] (1) Determine the scope of the watershed and carry out water ecological function zoning:

[0031] Carry out secondary zoning of the water ecological function area. The first-level zoning includes the average precipitation, average elevation, surface roughness, and land use intensity that can reflect the climate, terrain, soil, and vegetation natural environment elements of the watershed; on the basis of the first-level zoning , carry out two-level division, the second-level division includes the small watershed slope, channel tortuosity, water network density, water conservancy project density and small watershed pollution load that can reflect the habitat environment on the river reach scale and the impact indicators...

Abstract

The invention aims to provide a partition definition computing method for the river environmental flow of an artificially interfered area without hydrological data, and can effectively solve the computing problem of the river environmental flow of the artificially interfered area without hydrological data. On the premise of river water ecology function, the composition of environmental flow is defined, then the average runoff volume and annual distribution of the river in the area without hydrological data are studied by utilizing a hydrologic analogy method and a parameter contour line method; according to the flow data on this basis, the environmental flow of different partitions is computed, and the environmental flow of different nodes of the river is determined. The method is novel, unique and scientific, and is an environmental flow computing method based on functional requirements; and water resource optimization and deploying and water conservancy project ecology scheduling can be carried out on the rivers which are greatly affected by artificial interference degree and lack of hydrological data, so that the minimum environmental flow required for normally developing river functions is guaranteed, the river ecological system is repaired, the river ecological environment is protected, and the economic and social benefits are great.

Description

technical field [0001] The invention relates to environmental protection, in particular to a calculation method for defining and calculating river environmental flow partitions in areas without hydrological data due to artificial interference. Background technique [0002] The protection of environmental flow is the basis for maintaining the healthy development of river ecosystems, and is of great significance to maintaining the structure and function of river ecosystems. With the development of society and economy, the contradiction between the survival and development of human beings and the effective supply of water resources has become more and more prominent. The natural flow process of the river has a serious impact on the river ecosystem. In order to protect and restore river ecosystems, it is necessary to develop appropriate environmental flow calculation methods. [0003] At present, there are many calculation methods of environmental flow at home and abroad. The ...
