Synecological Characteristics and Vitality Analysis of the Berchemia berchemiaefolia Habitat

Abstract

This study was carried out to investigate vegetation and tree vitality of Berchemia berchemiaefolia habitat to recommend basic information for synecological characteristics. Totally 9 vegetation data were collected and analyzed. And one plant community (Quercus serrata-Berchemia berchemiaefolia community) including 43 families 66genera 72 species 8 varieties and 3 forma was differentiated. Quercus serrata-Berchemia berchemiaefolia community was subdivided into Typical subunit and Quercus mongolica subunit. Species showing the higer r-NCD value in the plant community were Berchemia berchemiaefolia, Quercus serrata, Lindera obtusiloba, Fraxinus rhynchophylla, Acer pseudo-sieboldianum, Corylus heterophylla var. thunbergii. In tree vitality result, Berchemia berchemiaefolia population containing 35 individual was estimated 3 monitoring categories; 1) General 2) Principal 3) Absolute. These categories frequencies arranged by the order General Monitoring (85.7%; 30 individual), Principal Monitoring (11.4%; 4 individual) and Absolute Monitoring (2.9%; 1 individual).
