摘要
采用回归分析的方法，对果用林的经济寿命进行量化分析，以果用林的果实连年产量和年均产量为指标，建立数学模型并求出经济伐期，为合理利用林地资源，延长果用林的经济寿命，增加单位面积产量，提高经济效益提供依据。
Quantity analysis on economic longevity of economical forest was made by adopting regression analytical method- Mathematics models were made by using in successive years yield and equal yield as index. Ascertain means of economic longevity of economical forest was introduced.
