A Study on Optimum Combination for the Intercrops of Chinese Prickly Ash Tree

运用多目标灰色局势决策法,对陕西省韩城地区花椒林下间作物的合理配置进行探讨.并对评价作物组合的指标权重加以调整,通过计算机数据处理将间作物配置局势优化排序,选出经济上合理、生产上可行的花椒林下间作作物组合,为生产运用提供直接的参考依据.

Through the method of multiobjective decision making of the grey system, the combination most suitable for intercrops intercropped with Chinese prickly ash tree, in Hancheng district of Shaanxi province, is explored. With the adjustment of indicators′ weight set up to evaluate the combination of intercrops, different situations of intercrops combinations are ranked through computer data processing. Then the recommended combinations of intercrops, as being economically reasonable and productively feasible, for intercropping with Chinese prickly ash tree are identified, which can directly serve as a reference for agriculture as well as forestry production.
