摘要
色季拉山报春花资源极其丰富,有12种及变种,文中编制了分种检索表,介绍了主要种类的生物学特性及其观赏价值。根据光照、温度、湿度及植被类型等因素将其生境类型归纳为4类:1.林内阴湿型,2.疏林透光型,3.林缘湿地型,4.高山冷湿型。报春花在本地区仅分布于海拨3000m以上地区,43％的种类生于海拨900m以上地区,具有明显的温带性。高山冷湿型生境的特点是低温高温,生于该生境型的种类多花大、色艳,观赏价值极高。生于林山阴湿型、疏林透光型生境的种类较易被驯化。
Tibet Sherjila Mountain is situated in 29°33'~30°0'N,94°9'~94°53' E, and at the elevations range from 2200~5300 m. According to the investigations in 1988~1990, there arc 12 species and varieties of primroses on this mountain. 1. Primula alpicola var. violacea,2. P.florin-dae,3. P .alpicola, 4. P. cawdoriana, 5. P .latisecta, 6. P. atrodent at a, 7. P. kongboensis,8. P.yargonensis, 9.P. advena, 10. P.calderiana,11. P.macro-phylla var. ninguida and 12. P.chungensis.The. biological characteristics and ormental values of the main species are presented in this article.
On this mountain,the primroses are distributed on the area over alt. 3000m. Among them, P.alpicola var. violacae and P.latisecta are only distributed on the west slope; P.yargonensis is only distributed on the east slope; P.kongbo2nsis,P.cawdoriana, P. calderiana,P. macrophylla var. ninguida and P.advena arc distributed on the areas over alt.4000 (3900)m.
According to the differences of temperature, humidity,illimination soil-water and vegetation, there are 4 kinds of primrose habitat type on this mountain: 1.Forest shade type,2. Sparse woods type, 3. Forestedge wetland type and 4. Alpine cold type.
