植物主要叶性状与微地形间相关性研究综述

Overviews on Research of the Interrelationships between Plant Main Leaf Characteristics and Micro-Topography Units

植物性状是植物在与环境之间相互作用过程中,为更好地生存与发展而形成的适应性特征。微地形借助环境因子的变化影响着其中光、热、水、土壤理化性质等其它因素的时空分配,从而形成相对异质性的微环境,为群落中物种间共存创造了差异性条件。同一物种在异质性的微环境影响下,逐渐会产生相应的性状变化,形成相应的适应性策略。本文通过对植物主要叶性状,包括比叶面积、叶干物质含量、叶片营养及叶数量与微地形之间关系的综述,阐明植物主要叶性状对微地形的适应性变化,为开展植物其它性状与微地形间的关系研究提供理论参考。

Plant characteristics are the adaptive properties formed in the process of interaction between plants and their environment. These characteristics are for plants’ better survival and develop-ment. Micro-topography controls the spatial redistribution of light, heat, water, soil physical and chemical properties and other environmental factors through the changes of surface morphology and geomorphic process which lead to form relative heterogenous micro-environment. It also creates heterogenous conditions for the coexistence of species in a community. The same species under the influence of heterogeneous habitats, it will gradually produce relevant characteristic changes and gradually form relevant adaptive strategy. In this paper, the interrelationships between plant main leaf characteristics and micro-topography units were reviewed. The main plant main leaf characteristics include specific leaf area (SLA), Leaf dry matter content (LDMC), foliar nutrition, and number of leaves. The adaptive changes of plant main leaf characteristics in response to micro-topography were clarified. This paper will provide a theoretical reference for the researches on the interrelationships between other plant characteristics and micro-topography units.
