摘要: 在黄海沙滩,天然分布着珊瑚菜、单叶蔓荆等重要经济植物的野生种群。由于砂质海湾是良好的海水浴场,每年夏季游客会给沙滩植物带来过度践踏。以青岛仰口沙滩为例,研究了游客践踏对沙滩草本群落的影响。结果表明,各种沙滩植物对践踏的忍耐性是不同的,珊瑚菜、粗毛鸭嘴草和猪毛菜等不能忍耐践踏,践踏不仅导致草本群落总盖度的降低,还导致物种丰富度的降低。

Abstract: There are some wild plants with high values (e.g. Glehnia littoralis and Vitex trifolia) on the sand-beaches of the middle Yellow Sea. The bays connected to the sand-beaches are suitable for swimming and tourism. Every summer, people gather there, causing heavy trampling on the plants. A case study on a sand-beach in Qingdao was conducted to ascertain the effect of human trampling on these plants. The tolerance of the plants to trampling differed: The species G. littoralis, Ischaemum bartatum and Salsola komarovii had the least to tolerance to trampling. Trampling led not only to a reduced grass coverage, but also to a reduction of species richness.
