| 摘 要： | 塞罕坝华北落叶松人工林的叶生长过程从每年４月下旬起至６月上旬完成。在叶生长过程中，叶长、叶面积和叶干重的增长曲线呈Ｓ型，其动态可用Ｌｏｇｉｓｔｉｃ生长函数描述，叶宽的增长过程可用Ｍｉｃｈａｅｌｉｓ－Ｍｅｎｔｅｎ方程描述。

| Abstract: | The leaf growth course
of a Larix plantation located in North China lasts from the last ten days of April to the first ten
days of June. In this period, growth courses of the leaf length(L),the leaf area(A)and the leaf
biomass(W)can be described by Logistic equation as follows:L=2.4603/(1+13.8468exp(-0.150
2t)),r=0.9942;A=0.2275/(1+17.8378exp(-0.165 1t)),r=0.9954: W=0.7996/ (1+14.618 7exp(-0.130
2t)),r=0.993 5. The growth course of the leaf width(B)can be described by Michaelis-Menten
equation:B=0.098 0t/(1.139 4+t),r=0.961 9. where,t is the time (days). |
