甘肃菊科饲用植物资源研究

The Forage Plant Resource of the Compositae in Gansu

通过整理标本、野外调查和查阅资料，对甘肃菊科饲用植物的地理分布、属种组成、区系成分及饲用价值等进行了分析研究。结果表明：甘肃菊科饲用植物区系成分多样，分布不平衡；粗脂肪含量较高，钙磷含量均为高水平。并对其利用保护提出了一些建议。

Gansu is located in a crossing zone of Loess Plateau, Mongolia Plateau and Tibetan Plateau. Due to the complex topography and diverified soil and climate, the species of the plants here is diverse. The flora and the forage value of the Compositae florage plant in Gansu are analysed. And some suggestions for conservation of the forage resource are put forward.
