Vegetation ecological assessment based on neutrosophic TODIM method with heterogeneous indicator information

The healthy development of vegetation ecology is closely related to biodiversity and ecological environment status. A new multi-source heterogeneous information processing method is proposed to deal with the complexity assessment of vegetation ecological resources. A crisp array-based fuzzy representation method is established. We define the consistency transformation function which maps linguistic information to a single-valued neutrosophic number. The constraint is established by using isomorphic forms to express the assessment indicators of vegetation ecological resources, and achieve consistent assessment of heterogeneous indicator information. The neutrosophic TODIM method was used to rank the plateau vegetation ecological resource situation in 12 regions. The results showed that the areas with the lowest ranking of vegetation ecological resources performed poorly in important indicators such as soil PH value, soil texture classification, and soil organic carbon status. The protection of vegetation ecological resources in the southeastern edge of the Qinghai-Tibet Plateau can be started from important indicators, to improve the vegetation ecological resources in the bottom-ranked areas.
