Comprehensive measure configuration method for realizing water-saving potential tapping in ecological irrigation area

Abstract

The invention discloses a comprehensive measure configuration method for realizing water-saving potential tapping in an ecological irrigation area and relates to the technical field of water saving. The method comprises the following specific steps: analyzing an existing irrigation district water-saving technology, setting water-saving measures, and calculating a water-saving potential evaluationresult; analyzing water-saving potential influence factors of an irrigation district, and establishing an entropy weight model under multiple constraint conditions; designing a new comprehensive water-saving configuration scheme according to factors such as planting structure adjustment; and realizing multi-scheme comparison and selection of comprehensive measure configuration of maximum ecological potential tapping by utilizing a pareto leading edge. By means of the method, ecological water saving and the like can be achieved to a greater extent, the waste of water resources can be effectively reduced, ecological balance and animal and plant species diversity of the irrigation district and surrounding areas are maintained, and the purpose of selecting an appropriate agricultural irrigation water-saving technology and a management mode conforming to the large-scale irrigation district can be helped.

Description

technical field [0001] The invention relates to the field of water saving in irrigation areas, in particular to a method for configuring comprehensive measures for realizing water saving and potential tapping in ecological irrigation areas. Background technique [0002] The most prominent problems in the ecological environment of large-scale irrigation areas in my country are: blind large-scale land reclamation, causing rivers to stop flowing, resulting in grassland degradation and regional ecological environment deterioration; excessive exploitation of groundwater leads to regional groundwater level drop, land subsidence, etc.; at the same time, there are still Waterlogging, salinity, soil erosion and other ecological and environmental problems. [0003] Although the water-saving measures implemented in the arid areas of Northwest China have brought huge benefits, excessive agricultural water-saving measures have also had a great impact. Although agricultural irrigation wate...
