摘要
以天然次生林皆伐迹地人工更新的7年生落叶松和水曲柳混交林带为对象,研究了不同坡位对落叶松与水曲柳带状混交相互关系的影响.由于坡位不同,各项生态因子发生变异致使落叶松对水曲柳的影响表现不一致.在早期,落叶松与水曲柳之间未接触以前,水曲柳地上的生长主要受环境因子的影响.落叶松对水曲柳生长的影响首先表现在根系上,然后反映到地上部分.
Taking 7-year old artificial mixed plantation between larch and manchurianash as object of study in the cutover area of nature secondary forest, theinfluence of the different parts of the slope on the relationship of line-mixedlarch and machurian ash plantation was studied. The influence of larch onmanchurian ash varied with changes of other ecological factors due to thedifferent parts of the slope. Generally the growth of manchurian ash is mainlyinfluenced by other enviromental factors, not by larch, before larch andmanchiurian ash touch each other in the early stage. Larch at first improves theroot system of manchurian ash, then improves the overground growth ofmandurian ash.
