Calculation method for determining water demand of natural wetland ecological environment restoration

Abstract

The invention relates to a calculation method for determining the water demand of natural wetland ecological environment restoration. The method comprises the steps that a wetland is divided into a wetland core region and a wetland ecological region according to a wetland ecological hydrological layout model, wetland data is acquired, and a regional range is determined; the range of the wetland core region is calculated according to critical moisture conditions, and an area guaranteeing ecological system integrity is utilized to represent and determine the range of the wetland ecological region; the water demand of wetland ecological environment restoration is divided into a wetland minimum ecological environment water demand and a wetland appropriate ecological environment water demand, and calculation is performed according to the regions; and a pollutant dilution and purification water demand is compared with a wetland organism habitat water demand, and the larger value is taken asthe wetland appropriate ecological environment water demand. According to the method, different methods are adopted for the wetland core region and the ecological region to calculate the ecological environment water demand, the method conforms to physical and ecological significance represented by the wetland minimum ecological environment water demand and the wetland appropriate ecological environment water demand, and therefore the calculation result is more accurate.

Description

technical field [0001] The invention relates to the field of resources and environment, in particular to a calculation method for determining the water demand of the natural wetland ecological environment, especially for the determination of the water demand of the ecological environment for restoration and development of the natural wetland, so as to ensure the ecological health and environmental stability of the wetland. Background technique [0002] Wetland is a unique ecosystem formed by the interaction of water and land, and it is the ecological landscape with the richest biodiversity in nature and one of the most important living environments for human beings. Under the background of climate change and intensified human activities, the area of ​​my country's wetlands has been greatly reduced, the ecological environment has continued to deteriorate, the hydrological cycle of wetlands has been severely damaged, and wetlands tend to be arid and threatened by degradation. ...

Problems solved by technology

However, its division of wetland eco-hydrological structure simply relies on remote sensing image data to judge the size of water area and the scope of wetland. The division method does not have complete physical meaning, and the ecological effect of the calculation results is not obvious.
