Evaluation and selection of introduced tree species in the Beijing-Tianjin corridor.

Abstract

Based on the extensive analysis of natural and social conditions, regional development, and characteristics of tree species in the Beijing-Tianjin corridor, a comprehensive evaluation index system that consists of A, B, C, D layers was established for introduced tree species. Nine local representative introduced tree species were evaluated using the analytic hierarchy process (AHP). The results showed that Platanus orientalis, Quercus mongolicus, and Zizyphus jujube performed better comprehensively and were recommended as the dominant introduced tree species in the Beijing-Tianjin corridor. Other representative introduced tree species should be appropriately developed in the region. Main factors that should be taken into account for introduced tree species including drought tolerance, wintering habit, growth rate, leanness tolerance, pollution tolerance, saline tolerance, and disease resistance.
