摘要
提出一个测定季节性集中换叶乔木叶面积指数的新方法——收集落叶法的构想,并由此推广到旷地单株乔木、纯种林分、均匀混交同季落叶林,以及渐次落叶乔木4种情况.提出了相应的统计公式,对方法的可行性从理论上作了探讨.
In this paper, a new measurement method for tree leaf area index has been presented by the authoy It is termed collect decidous leaves method. It can overcome two difficulties: l.about tree height problem in research; 2-about tree leaf number problem. According to different study objects, the author provides different formulas respectively. As for the possibility of the use of this method, the author has also studied theoretically.
