摘要
本文采用多目标灰色局势决策的方法，以桐麦间作人工群落为例，以１０年为泡桐生长的一个轮伐期，以６种不同的空间配置方式作为对策，以林业经济收益、农业经济收益和系统总体效益为目标，进行多目标决策，定量研究其空间分布格局。研究结果表明，以农为主间作型泡桐的最佳株行距为５×４０ｍ，以桐为主间作型的为５×５ｍ，农桐并重间作型的为５×２０ｍ。
In this paper,the author made a quantitative study on a spacial pattern of Paulowina-wheat intercropping a-groforestry system wiht the mathematical methods of GreyControl System taking 10 years as a rotation period with dif-ferent spacial density treatments,the author derived a model decision optimum spacial pattern of Paulowina-wheat agro-forestry system ,by using a multi-objective Grey Sitution De-cixion. It is concluded that:(1) with priority given to agricul-tural production,the optimum spacial pattern is 5×40m ;(2)with priortty given to forestry production,the optimum spaLcial pattern is 5×5m and (3) with priority given to agricultural and forestry production,the optimum spacial pattern is 5×20m.
