摘　　要：对7种地被植物进行不同程度的遮阴处理,结果发现:九头狮子草、大吴风草和虎耳草在全光照下生长不良,出现斑叶、枯叶甚至死亡现象,随着遮阴强度增加,生长变好。多花筋骨草、聚合草和东方草莓在全光照和不同遮阴条件下生长差异较小,表现出较强的光适应性。百里香在全光照下生长发育良好,遮阴下生长减缓,甚至不开花,表现不适。7种地被植物随着遮阴强度加大比叶重下降,以百里香最为明显,九头狮子草、大吴风草和虎耳草下降幅度较小。九头狮子草和虎耳草在全光照下最大光化学效率偏低,耐光性弱。综合各指标看,虎耳草、九头狮子草和大吴风草为喜阴植物,百里香为喜阳植物,其他种类为中性植物。Seven groundcover species were cultivated under different shading treatment. The results showed that the growth of Peristrophe japonica, Farfugium japonicum and Saxifraga stolonifera was unfavorable under full sunlight and became better with increasing shade. The growth of Ajuga multiflora, Symphytum asperum and Fragaria orientalis showed little difference under different sunlight. Thymus mongolicus grew best under full sunlight and became weaker with increasing shade. The specific leaf weight（SLW） of seven groundcover species decreased with increased shade, among which Thymus mongolicus decreased greatly, while Farfugium japonicum, Peristrophe japonica and Saxifraga stolonifera decreased slightly. The latter two species had lower photochemical efficiency under full sunlight. It is concluded from above evidences that Saxifraga stolonifera, Peristrophe japonica and Farfugium japonicum are shade plants, Thymus mongolicus is a sun plant, and that other three species were intermediate plants.
