摘要
通过对典型黄土丘陵沟壑区(晋西北河曲县)的人工行实地考查,应用灰色多目标局势决策理论,根据不同地形部位选择了5种有代表性的土壤类型作为事件集和5种常见的树种作为对策集,从经济效益、水保效益、生物产量和改土效果等4方面,对25个营林局势进行了综合分析,指出了各土壤类型适宜的最佳营林树种。
Based on the spot investigation of artificial of artificial forest in Hequi county in the represenatative loessHilly-gully Area, Northwest of Shanxi Province, the multiple objective grey state decision makingmethod was used for the synthetic analysis of 25 afforested states, which were consisted of eventswith 5 representative soil type in different topography and games with 5 common spcies of tree from4 aspots as economic effect, soil water conservation ability, yielding capacity of biomass and im-proved soil productivity. At last, is suggested the preferential species of afforestation in different soiltypes.
