干热河谷区具有季节性干旱明显、热量丰富、土壤退化等环境特征,其独特的气候和脆弱的生态环境特征制约了该区的经济发展,生态环境脆弱,是中国生态建设的难点和生态恢复的区域。通过相关文献的查阅、概括与归纳,简要评述了云南省干热河谷典型区环境特征、草地植物群落特征以及存在问题,提出干旱型草地资源的保护和利用建议,以期为本区草牧业的发展、草地生态建设和恢复提供参考。

The dry-hot valley was prominent with the environment characteristics of heat richness,obvious seasonal drought-wet,broken terrain and serious soil erosion.The dry-hot valley economic was restricted by the unique climate and ecological environment characteristic..With the ecological fragility,the dry-hot valley was recognized to be a symbol of difficulty in ecological construction and restoration.Though the overview and summary of the latest researches,the environment characteristic,grassland community and remain questions of dry-hot valley were discussed,and the paper proposed the rational utilization and prodtection of dry type grassland resources in order to provide reference for the grass husbandry,construction and restoration of grassland ecology.
