摘　　要：根据不同立地条件类型和不同树种的区位适宜性 ,合理配置树种 ,是确保成活、成林的关键。为了有效恢复黄土高原重点水土流失区的森林植被 ,治理水土流失 ,促进西部大开发中的生态环境建设 ,采用“综合评判法”和“生物生态类比法” ,对黄土高原重点水土流失区人工栽培乔木树种区位适宜性的评价原则、评价方法进行了论述与分析。结果表明 ,这 2种方法均较为适宜对该区人工栽培乔木树种的评价。最后 ,用“综合评判法”确定了该区 7个类型区的适生乔木树种 4 6种 ;用“生物生态类比法” ,确定了建议树种 4 7种。It is a key points to assure the tree survival and afforestation to allocate trees properly according to the different site conditions and adaptability of different trees. The mothod of “comprehensive evaluaiton method” and “anologism of biology and ecology” are used to study the evaluating principle, method of the adaptibility of the artificial arbor trees in the main areas of losses of soil and water of the Loess Plateau for rehabiliation, harnissing the lossses of soil and water, and promoting the evironment construction in the Development of Western China. The results show that two methods are suitable to evaluate the arbor trees in the areas and 46 suitable arbor trees have been gained with the aid of the first method, and 47 suggested arbor trees have been dertermined from the second mothod.
