This invention belongs to the field of ecological restoration technology and relates to a method for screening species for the restoration of damaged ecosystems based on seed functional traits. It addresses the problems of lack of scientific basis for species selection, low establishment success rates, and potential biological invasion risks in existing restoration practices. Principal component analysis is used to extract key trait combinations, and hierarchical clustering analysis is performed based on principal component scores to classify functional groups with different restoration strategies. An adaptive evaluation mechanism is constructed to assess the relationship between multidimensional seed functional traits and field establishment, identifying and predicting the environmental adaptability and establishment capacity of candidate species. A screening system encompassing seed trait measurement, functional group identification, and field establishment rate prediction is established, transforming species selection from a traditional reliance on engineering experience or subjective judgment to a data-driven process, thereby improving the repeatability and reliability of the screening results.

The present invention belongs to the field of ecological restoration and discloses a forest ecological restoration method based on community integrity and functional traits, including S1, obtaining the community integrity index (CCI) of the study area; S2, determining whether the CCI is greater than 0. If so, the species in the study area are protected; if not, entering S3; S3, obtaining the dark diversity probability of the species in the study area; S4, selecting species with a dark diversity probability less than a set threshold as candidate species; S5, constructing an underdetermined equation system based on the expected values ​​of the functional traits of the candidate species to solve the relative abundance of the candidate species; S6, performing species restoration based on the relative abundance of the candidate species. The present invention can quantitatively assess missing species in the community, predict the abundance ratio of restoration species, and optimize functional restoration combinations, solving the problem that traditional species selection based on reliance on existing community structure alone cannot accurately identify potential restoration species and achieve function-oriented restoration configuration.

The invention belongs to the field of ecological restoration, and discloses a forest ecological restoration method based on community integrity and functional traits, and the method comprises the steps: S1, obtaining a community integrity index (CCI) of a research area; s2, whether the CCI is larger than 0 or not is judged, and if yes, species in the research area are protected; if not, entering S3; s3, acquiring dark diversity probability of species in the research area; s4, the species with the dark diversity probability smaller than a set threshold value serve as candidate species; s5, constructing an underdetermined equation set based on the expected values of the functional traits of the candidate species, and solving the relative abundance of the candidate species; and S6, performing species restoration treatment based on the relative abundance of the candidate species. According to the method, the community missing species can be quantitatively evaluated, the abundance proportion of the restoration species can be predicted, the functional restoration combination can be optimized, and the problem that potential restoration species cannot be accurately identified and function-oriented restoration configuration cannot be realized due to the fact that species selection is carried out based on a traditional method only depending on an existing community structure is solved.
