硬叶柳叶片形态在海拔梯度上的演变
|
Abstract:
本文以那曲嘉黎县9个海拔梯度上的硬叶柳为研究对象，采用叶面积仪测量叶片的长度、宽度、厚度，并计算叶片面积和叶形指数。在4000 m~4800 m海拔梯度上，硬叶柳叶片长度、宽度、厚度和叶面积的演变均呈现二次方程。随着海拔的升高，叶片的长度、宽度、厚度以及叶面积起先均有下降趋势；当海拔达到4500 m时叶片各参数到达最低值，然后随海拔的上升而上升。
In this paper, Salix sinensis on nine elevation gradients in Jiali County of Naqu was taken as the research object. The length, width and thickness of the leaves were measured with calipers, and the leaf area and leaf shape index were calculated. On the 4000 m~4800 m elevation gradient, the leaf length, width, thickness and leaf area of C. satifolia showed a quadratic equation. With the increase of altitude, leaf length, leaf width, leaf thickness and leaf area initially showed a downward trend. When the altitude reached 4500 m, the leaf parameters reached the lowest value, and then increased with the increase of altitude.
