摘要
本文根据对黄土高原林业生产的考察研究,选取了土壤肥力、土壤酸碱度、水分、热量、地形部位、坡向和土壤种类等作为选择造林树种的限制因子,得到138个有效组合作为事件集,用66个常见的造林树种作为对策集,通过多目标模糊决策,求得各事件集上适宜的造林树种,最后应用灰色局势决策,求得了各事件集上最优造林树种,计算结果与实际调查基本相符合。
According to the investigation conducted on the Loess Plateau with regard
to its forestry production, the paper deals with the selecting of tree species
while taking the soil fertility, acidity, moisture content and the quantity
of heat as its limiting factors in silviculture. As a result, 81 combinations
of events were got as effective in decision-making and 66 species of trees
commonly used in silviculture were chosen as sets of games, based on which
the suitable silvicultural tree species were got through multiple-obiect fuz-
zy decision for each event and the best species got for each event through
Grey situation decision. The calculation is basically in conformity with the
practiced investigation.
