【摘要】 研究了内蒙古多伦典型草原14种植物的比叶面积对水分梯度的响应,结果表明:典型草原植物比叶面积(SLA)与水分梯度之间并不存在简单线性关系,不同水分梯度下典型植物叶片SLA变化比较复杂,并非简单依照植物生长型如:禾草类、豆科类以及杂类草等进行变化。更多还原

【Abstract】 The response of specific leaf area(SLA) of 14 plant species to water gradient was investigated in a typical steppe of Inner Mongolia.The results showed that no simple linear relationship was found between the specific leaf area(SLA)and water gradient.The leaf traits of 14 typical plant species varied and were not simply in accordance with their respective growth forms,such as the categories of grasses,legumes and forbs.更多还原
