The invention provides a
phoebe zhennan tree species introduction and conservation method in an alluvial plain area, and relates to the technical field of
agriculture and
forestry, A, planting a plurality of to-be-introduced
tree species in an introduction site, calculating an average physiological index membership value and an average rank of each to-be-introduced
tree species, and screening the average physiological index membership value and the average rank which are ranked from large to small and are less than or equal to 50%, or the to-be-introduced tree species of which the average rank ranks from large to small are less than or equal to 50%, the average
chlorophyll content ranks from large to small are less than or equal to 10% and the average
seedling height ranks from large to small are less than or equal to 65% are suitable
germplasm; and B, planting suitable
germplasm in the suitable region of the introduction site. The screened suitable
germplasm has strong adaptability to the introduction land, the introduction and conservation success rate of the
phoebe zhennan tree species in the introduction land is improved, the arbor tree species in the introduction land are enriched, and the
biodiversity selection of the introduction land is improved. The technical problem that in the prior art,
phoebe zhennan tree species are difficult to introduce in an alluvial plain area in an ex-situ mode is solved.
