Abstract

The invention relates to a watershed water resource management method based on supply type hydrological ecosystem service, which comprises the following steps: analyzing basic information acquired bysimulating a mechanical watershed hydrological model to obtain a total water yield, and taking the total water yield as the supply type hydrological ecosystem service to obtain a supply type hydrological ecosystem service spatial distribution diagram layer; quantifying the economic value of the supply type hydroecological system service by adopting a market value method to obtain an economic valuespatial distribution diagram layer; and simulating watershed water resource protection and division of a potential development area according to the two spatial distribution map layers by adopting aspatial ecological planning model. According to the invention, the influence and relative importance of land utilization change, soil properties, climate, terrain and the like on space-time distribution of water yield are analyzed by utilizing a mechanical basin hydrological model, and a water resource area needing to be protected emphatically and a water resource area potentially developed are identified by combining a space ecological planning model, so that the comprehensiveness and effectiveness of water resource protection are improved.

Description

technical field

[0001] The invention relates to the technical field of water resource management and planning, in particular to a water resource management method for a watershed based on supply-type hydrological ecosystem services. Background technique

[0002] Water is an essential precious natural resource for human survival and production activities. In recent years, with the increase of population and rapid economic development, the contradiction between supply and demand of water resources has become increasingly serious. my country's per capita water resources are small and unevenly distributed in time and space. It is a typical structural water-scarce country. Taking water resources in river basins as a key element in the protection planning of natural ecological resources (supply-type hydrological ecosystem services) has become a key element in the protection planning of relevant government agencies and academic institutions in my country. general consensus in the w...
