摘要
运用于层次模糊综合评判模型，对北京九龙山主要４种森林植被类型涵养水源效能进行了综合评判，结果表明，油松林水源涵养综合效益最好，其次为阴坡灌木林和侧柏林，阳坡灌木林最次，并据此分析了该４种类型的经营、保护和利用措施。
Multiple-layer Fuzzy comprehensive evaluation was used to evaluate the function of wa-ter preservation of four forest vegetation types. The.results showed that Pinus tabulaeformis forest was the best.shrubery in north aspect and Platycladus orientalis forest were the second and shrubery in southaspect was the most inefficient for water preservation.The rational managing measure of facilitating af-forestation and protecting vegetation can be made on the basis of the results.
