井冈山大果马蹄荷林种群生态数量场的研究

A STADY ON THE NUMERICA FIELD OF ECLOGY OF THE NATURAL Exbucklandia Tonkinesis FOREST IN JINGGANGSHAN MOUNTAIN

通过对大果马蹄荷林种群数量与最短邻体距离的方差变化规律以及随空间距离的相关变化分析 ,并引入相应的生态数量场 ,得到了大果马蹄荷林生态数量场势函数(r) :(r) =14541+S0 .90 2(t) r1.4分析了(r) 与密度规律、Logistic规律以及周期性阻尼振荡规律的关系 ,认为(r)

Analysing the law of relative changes among the number of species and variance of the shortest neighbourhood distance and the spatial distance to the oldest seed tree of Exbucklandia tonkinensis by introducing the theory of ecologic field,we have obtained a function in this paper as follows: \ \  (r) =1 4541+S 0.902 (t) r 1.4 Meanwhile,the  (r) was checked and compared with the law of density,logistic equation and periodicity,it is considered as important significance to apply the periodicity of  (r) and its β to ecological management practice.
