为什么某些植物生长在某些栖息地,而不是在其他地方?植物群落之间区系差异的原因是什么?如果这些问题被问到“正常”,我。例如,物种相对丰富的恒定的自然或人工植物群落(10-20株以上),如果没有单一的极端,则为E.例如,在一个实施例中,气候或有毒因素或人为干扰发生时,答案是整个星座的因素(见,e。例如,在一个实施例中,Billings 1974,第26页)。然后又出现了另一个问题。哪个因素最重要?一般来说,在生理生态水平上寻求单一因素,即。例如,直接(立即)作用于植物的因素,例如土壤的铝离子含量、霜冻、干旱、践踏、啃食等。
Why do certain plants grow on certain habitats and not on others? What are the causes for floristic differences between plant communities? If these questions are asked for “normal”, i. e., relatively species rich constant natural or seminatural plant communities (more than 10–20 phanerogams) and if no single extreme, e. g., climatic or toxic factor or human interference occurs, the answers are whole constellations of factors (see, e. g., Billings 1974, p. 26). Then a further question arises. Which is the most important factor? In general, single factors on the ecophysiological level are sought, i. e., factors acting directly (immediately) on the plant, like for example aluminum-ion content of the soil, frost, drought, trampling, browsing etc.
