The invention relates to the technical field of water conservancy projects, and discloses a longitudinal ecological compensation-based cross-regional basin
resource allocation optimization method, which comprises the following steps of: acquiring cross-regional basin
monitoring data; constructing a cross-regional
drainage basin resource allocation optimization model; a longitudinal ecological compensation parameter uncertainty set and an
ellipsoid uncertainty set are introduced into the cross-regional
drainage basin resource allocation optimization model, and a cross-regional
drainage basin resource allocation double-layer
robust optimization model is constructed; and the uncertainty set is converted into a deterministic condition by adopting robust peer-to-peer transformation, then the cross-regional basin resource allocation double-layer
robust optimization model is converted into a single-layer planning model by adopting a KKT condition, and an optimal ecological protection cost and emission capacity allocation scheme is solved. According to the method, the double-layer multi-target
robust optimization model is adopted, and the
pollutant concentration index of ecological compensation is introduced, so that a fair and reasonable
decision scheme is obtained, and accurate configuration of environmental resources is realized.
