摘　　要：针对我国平原农区农田防护林建设的现状及近年来的研究成果，对防护林的数量成熟龄、工艺成熟龄、防护成熟龄、经济成熟龄进行了深入探讨，提出了各种成熟龄的确定方法。在生产实践中，农田防护林的采伐年龄应取４种成熟龄的上限，当在伐期龄不能采伐时，宁可推迟也不要提前采伐。同时，对防护林成熟的可变性、成熟龄的表示方法、林带本身对成熟龄的影响及伐期龄的应用等问题进行了讨论。Based on the construction situation of shelter forest for farmland in rural plain area and the recent research achievements, the paper discussed the maturity ages of largest volume, technology, protection and economy of shelter forest belt for farmland. The determining ways of the four ages were also given. In practice the final cutting age should be the upper limit of the ages. If the forest belt can’t be cutted during the final cutting age, its was better to implement the cutting after the age. At last, the paper discussed some problems such as the variety of forest maturity, the expression of maturity age, effect factors on shelter forest maturity and the application of final cutting age.
