[0026] The calculation formula in the ecological security index calculation module 154 is:

[0027] ESI: Ecological Security Index, a quantitative indicator of wetland ecological security. Its value directly reflects the safety of the wetland ecosystem. A higher value generally indicates better ecological security, while a lower value indicates risks. n: represents the number of ecological indicators involved in the calculation. Wetland ecosystems are very complex, and multiple indicators are usually required to comprehensively assess their ecological security. These indicators may include water quality, biodiversity, vegetation cover, soil quality, etc. Wᵢ: is the weight of the i-th ecological indicator. Weights reflect the relative importance of the indicator in assessing ecological security. Weights are typically determined using various methods, such as the analytic hierarchy process (AHP) and the Delphi method. For example, in a wetland ecosystem, if biodiversity is crucial to overall ecological security, the weight w corresponding to the biodiversity indicator may be relatively high. xᵢ is the standardized value of the i-th ecological indicator. Because different ecological indicators may have different dimensions and numerical ranges, each indicator needs to be standardized in order to be able to combine them for calculation. There are many methods of standardization, the most common of which is range standardization. For example, for a certain indicator value y, its range standardization formula is:

[0028] Among them, y min is the minimum value of the indicator, y max is the maximum value of this indicator.
