摘　　要：该系统在微机的支持下以不同的立地条件及不同经营措施的生长指标划分了四种泡桐生长模型,以此作为“事件”,再分别以间种不同密度级的泡桐作为“对策”,结合年龄的制约条件,对要求泡桐蓄积年平均生长量最大、林业经济收入最多、农业经济收入最多或总经济收入最多为四个经营目标。用人机对话形式输入以上要求,系统便自动运算,求出所要求的经济效果数值,也可显示决策后的具体指标,如胸径、树高、单株材积、立木蓄积、枝叶生物量及各种经济收入数值,以检验决策正确性。Under the support of comPuter, the system makes four growth-patterns of Pauiownia with different site types and growth-indexes of manage-measures, regarding these patterns as events, Paulownia intercropped in different density-scales as countermeasures and the age as restrict. Taking the greatest Paulownia growing stock average growth quantity per year, maximum forestry income, maximum agricuhure income and total economic incomes for four objects, input all these to computer with the man-machine interaction, the computer calculated automatically, and output some (?)alues of economic results we needed, and displayed some indexes, such as d. b. h, tree height, tree volume, growing stock, branches and leaves, various economic incomes, and so on. to ex amine the correctness of the policy-making.
