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 Yellow River Delta is one of the largest in China. Grasslands are the major natural vegetation types in the region. Phragmites australis community, Imperata cylindrica community, Primula pubescens community, and Sapium salsa community are the four basic types of grassland. This paper studies their properties and their environmental factors. Grassland average annual yield of up to 2000 kg / hecta. Separating the grazing area from the mowing area, controlling the timing and intensity of grazing, limiting the herd size and properly reforestation are important ways to make rational use of grassland resources. The establishment of nature reserves for scientific research, grassland ecosystem protection is necessary.
