| 摘 要： | 黄河三角洲是中国最大的三角洲之一。草地是本地区主要自然植被类型。芦苇群落、白茅群落、獐茅群落和盐地碱蓬群落是该草地的4个基本类型。本文研究了它们的性质及其环境因子特征。草地的平均年产草量可达2000 kg/hecta。将放牧区与割草区分开、控制放牧的时间和强度、限制牧群的数量以及适宜地造林是合理利用草地资源的重要途径。建立自然保护区对于科学研究、草地生态系统的保护是必要的。

The grassland is main type of natural vegetation in this area, there are four basic types: Phragmites communis community, Imperata cylindrica vat. major community, Aeluropus littoralis var. sinensiS community and Suaeda salsa community. This paper studied their feature and its charecter of environmental factors. The everage yield is about 2000 kg/hecta. Meatures to seperate grazing districts from cutting districts and to control the time and,intensity of grazing and cutting are appropriate. In order to improve ecological environment and enhance ecological benifit, planed afforestation is favorable. |
