摘要: 松嫩平原位于我国东北中部,其范围大致是:北纬43°30’—48°40’,东经121°30’—127°00’。总面积约17万平方公里(图1)。在广阔的平原上,河流纵横,水源丰富,土层深厚。分布在平原上的草原具有草质优良、产草量高、毒害草少的特点,是我国和世界上最好的草原之一,也是发展以畜牧业为主,牧、农、林结合的重要基地。因此,松嫩草原植被的研究,具有重要的实际和理论意义。

Abstract: This paper describes vegetation on the Songnen Plain and classifies vegetation types in steppes,meadows and swamps.The authors not only discuss the ecological condition of steppe vegetation,the constituents of plant population on the Songnen Plain,and their bacie types and succession,but also approach some ways of artificial improvement on natural steppes.In this region,there are 27 associations which are suitable for grazing and 450 plant species which are suitable for forage.Among them,more than 30 species belong to fine grass of perennial gramineous and leguminous plants.
