摘 要(英文)：Ecosystem and human surroundings were heavily influenced by acid rain pollution. In order to provide a scientific basis for selection of plant species for reconstructing the degraded ecosystem, it is necessary to study the sensitivity and resistance of woody species as well as acclimatization to air pollution stress. This study aims to characterize the ecophysiological responses of three woody species (Schefflera octophylla, Schima superba and Pinus massoniana), grown at the Xiqiaoshan, near ceramic factories, where the pollution is heavy, and at the Dinghushan Natural Reserve, a relatively clean site. Both sites are located in the Pearl River Delta area of south China, and similar in climate and geolocations. The results showed that: growing in the polluted environment, cell membrane leakage rate of leaves was increased, content of photosynthetic pigments and maximal photochemical efficiency of PSII were decreased; The sensitivity sequence of three species to acid rain was: Pinus massoniana >Schefflera octophylla≥Schima superba,
and Pinus massoniana was the most sensitive specie of all the three. Some physiological mechanism of tolerance of woody
plants to acid rain pollution was also discussed in this paper.
