The core of the biological resource index evaluation algorithm is to process the population size of each organism. By multiplying the ecological importance weight of the organism, it can reflect the contribution of different organisms to the ecosystem, and introduce adjustment items to reflect the impact of changes in the population size of organisms on the overall biological resource index; The adjustment item compares the population size of the organism with the preset ecological threshold value, calculates the difference between the population size of the organism and the ecological threshold value, and processes the difference through an exponential function, so that the impact of the change in the population size of the organism on the biological resource index has a smooth characteristic, ensuring the sensitivity of the biological resource index evaluation algorithm to the change in the population size of the organism, while avoiding the excessive impact of extreme values ​​on the overall biological resource index; The calculation formula for biological resource indicators is: , in, Indicates at time indicators of biological resources; Express The sum of all species is calculated, which integrates the resource status of different species; Indicates The ecological importance weight of the species; Indicates adjustment The impact of species populations on biological resource indicators; It represents an exponential function, which smoothes the impact of changes in biological populations on biological resource indicators; Indicates Ecological thresholds for species are set based on ecosystem research and expert opinion; S2.

The nonlinear changes in market demand are reflected by the logarithmic growth of the population size of the organisms. The logarithmic growth can reflect the trend that the nonlinear transformation of market demand gradually slows down as the population size increases, and is used to adjust the basic economic value of the organisms to ensure that it is close to the actual market situation. In order to further reflect the sensitivity of the market saturation effect to changes in the population size, the market saturation effect is calculated based on the population size of the organisms and the inflection point of the market saturation effect; The specific calculation formula of economic benefit index is: , in, Indicates at time Economic benefit indicators; Express The economic benefits of the species are summed up; Indicates species in time the market price of Indicates The market response coefficient of a species is used to reflect the market's sensitivity to changes in the population of the species and is determined based on expert opinions; Indicates species in time The logarithmic growth of the population is used to reflect the nonlinear changes in market demand; represents the saturation effect of the biological population on market demand, where represents the exponential function; It indicates the inflection point of the market saturation effect, which can be set according to the specific implementation scenario and is not limited here; S3.

The comprehensive assessment algorithm for marine ranch resource management adopts a nonlinear combination of logarithmic functions and exponential functions. The biological resource indicators are logarithmically processed to reduce the impact of extreme values ​​on the assessment value, and the economic benefit indicators are improved through the power exponent, divided by the logarithmically processed biological resource indicators plus 1, and further processed using an exponential function, which reflects the dynamic relationship between economic benefits and biological resources, and captures the complex interactive effects between economic benefits and biological resources through nonlinear adjustment; the change rate of biological resource indicators and the change rate of economic benefit indicators respectively reflect the changes in biological resource indicators and economic benefit indicators over time. The rate of change of bioresources and economic benefits is thus provided; The specific calculation formula for the comprehensive assessment value of marine ranch resource management is: , in, Indicates at time Comprehensive assessment of marine ranching resource management; It indicates that the biological resource indicators are logarithmically processed to reduce the impact of extreme values ​​on the comprehensive assessment value of marine ranch resource management; The power index of the economic benefit index is used to adjust the nonlinear relationship of the economic benefit index.
