Abstract

The invention discloses an ecological water right space-time configuration method and system; the method comprises the steps: constructing an ecological network in a to-be-decided region, and carrying out the grading of the water right of an ecological gate based on the ecological network; in the current water distribution year, determining the maximum water distribution amount of each ecological gate under the current water right level according to the water shortage degree of the ecological gates in the rotation irrigation period; performing water distribution on the ecological gate under each water right level in combination with the remaining ecological available water amount in the current year; in the next water distribution year, if the water right level which is not completely met exists, conducting water distribution on the water right level firstly, and then performing gradient water distribution, and otherwise, performing water distribution from the water right level with the highest priority. Therefore, the importance of ecological water supply in different areas is distinguished by applying the ecological network, so that the water right level of the ecological gate is divided, finally the engineering application of the ecological water right is realized through the time sequence distribution and the same-level distribution of the ecological water right, and therefore, scientific guidance can be provided for ecological water right configuration in drought and water-deficient areas.

Description

technical field [0001] The invention belongs to the technical field of efficient utilization of water resources and ecological restoration, and more specifically relates to a method and system for spatiotemporal allocation of ecological water rights. Background technique [0002] The allocation of ecological water rights is based on the calculation of ecological water demand, and water rights are assigned to various types of ecological water inside and outside the river basin. In some existing studies, when configuring ecological water rights, the spatial scale is usually measured in river basins, and the time scale is basically calculated in years (consistent with the time scale for calculating ecological water demand). macro description. Due to the large spatial scale, it is difficult to match the quantity of ecological water rights with the incoming water and ecological water demand of the basin. Such achievements are still far from guiding the actual ecological water su...
