蓼

We measured the photosynthesis of Roegneria kamoj, Polygonumsphaerostachyum, Koeleria cristata, Kobresia myosuroides, Ligularia sagitata and Anaphalis lacteal under different soil status and investigated the variations ofcommunity composition after fertilizer to find out the mechanism ofαdiversityformation at local community level. At metacommunity level, we compared the effectsof distance and environmental gradient on the community similarity indexes of fourdifferent locations in two hills to seek the mechanism of D diversity formation.

在局域群落中，以高寒草甸植物群落的重要组分种：鹅观草、球花蓼、洽草、嵩草、箭叶橐吾和乳白香青为对象，通过施肥处理后光合能力以及群落结构的变化探讨α多样性的形成机制；在集合群落水平上，通过对比两座相距180 m山坡上4个不同坡向样方间群落相似性与距离和环境梯度的相互关系，探讨β多样性的形成机制。
