摘要
以碱茅人工草地为研究对象，对植物量的季节动态和垂直分布规律、植物量与主要生态因素的关系、生态因素及其交互作用对植物量的影响进行了研究，为盐渍化草地的生物改良提供基础资料和理论依据。
This study was carried out on a Puccinellia grassland at Linze,Gansu.The study dealswith the:seasonal and spatial changes in the phytomass of above-ground part and un-derground part of Puccinellia.Relationships among primary production and major eco-logical factors were analized.The method of path coefficient analysis was used to study the direct and indirect effects of 4 ecological factors on the phytomass.
