摘　　要：通过对甘肃省主要林区的落叶松人工林的实地调查，根据防护成熟的基本理论，用层次分析法在多因子判断防护林的综合防护成熟中的应用，结合经济成熟的研究，最后确定防护成熟龄。Adminitrative analytical method for many variable was used todecide the synthetical protected maturity of shelter, based on the investi-gation on the spot of Larix man-made forest in Gansu province. The realisticprotected maturing age was defined according to the study of economicalmaterity in combination with the result.
