摘　　要：选择Ｒｉｃｈａｒｄｓ生长函数Ｈ＝ａ（１－ｅ－ｂＡ）ｃ作为辽宁省刺槐优势高生长模型．用差分法展开导向曲线编制了单形立地指数表；应用分组整理后解析木资料，拟合出最优多形立地指数模型，编制了多形立地指数表．在综合分析影响刺槐生长发育的环境因子基础上，选择了７个立地因子，运用数量化理论Ⅰ方法，建立与立地指数的回归模型，经减少项目法筛选出包含５个因子的立地指数最佳预估方程，编制了数量立地指数得分表．Richard function H=a(1- e -bA ) c was taken for dominant height growth model of Robinia pseudoacacia in Liaoning province.Single form site index chart was constructed after derived curve was expanded.By means of the adjusted stem analysis data,polyform site index chart was also constructed.On the basis of comprehensive analysis of environmental factors that influenced the growth of Robinia pseudoacacia ,seven factors were picked out and used for site index,equation construction by using quantitative theory I.Through factor reducing method,five factors were selected.To build the optimum equation,quantitative site index score chart was constructed.
