| 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2000kg/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。

| Abstract: | The Yellow River Delta is one of the three biggest deltas in China. The grassland is main type of natural vegetation in this area,there are four basic types:Phragmites communis community,Imperata cylindrica var.major community,Aeluropus littoraIis var.sinensis community and Suaeda salsa com- munity.This paper studied their feature and its charecter of environmental factors.The everage yield is about 2000 kg/hecta.Meatures to seperate gra- zing districts from cutting districts and to control the time and intensity of grazing and cutting are appropriate.In order to improve ecological environ- ment and enhance ecological benifit,planed afforestation is favorable. |
