五台山山地草甸资源及其利用

Resources and Utilization of Mountain Meadow on the Wutal Mount.

本文研究了山西省五台山山地草甸资源的类型、分布特点、牧草产量及营养价值，并提出了合理利用的意见。五台山草甸总面积为８４３９１公顷，高山草甸主要分布在海拔２７００米以上的山地，产草量较低、营养丰富；亚高山草甸包括苔草草甸、五花草甸及野青茅草甸，主要分布在海拔２０００～２７００米的山坡，其牧草种类丰富、营养完善、产草量高，是理想的夏季放牧地。

Grassland types ,characteristics of distribution,herbage yield and nutritional value of mountain meadow on the Wutai Mount in Shanxi were studied.Suggestions for rational utilization of the grassland were made. The total area of the meadow is 84,391 hectare. Alpine meadow is mainly distributed over the mountains of more than 2, 700 metre above the sea level.On the alpine meadow herbage yield is low, but high quality. Sub- alpine meadow which included Carex spp.meadow, multicoloured meadow and Deyeux- ia sylvatica meadow is usually distributed over the slopes of 2 ,000─ ─2 ,700 meter above the sea level.The herbage species is rich on the subalpine meadow. Herbage yield is high with high quality.Both alpine meadow and subalpine meadow are fine summer pastures.
