森林管理者需要新的方法来维持高林分蓄积量，同时保持森林持续的生产力和经济效益。造林管理系统（SMS）通过增加定期采伐的大型树木来实现这些目标，并不断将林分量保持在尽可能高的水平。该系统利用了天然林生态系统中广泛存在的树种的生长、活力和优势树的多样性。根据北海道东京大学森林开发的SMS，通过移除最老的成熟树木，以8-10年的采伐周期采伐13-17%的林分。剩余林分积保持在自然老林分的70-80%左右。这种移除最古老树木的做法使林分一直处于健康和多产的状态。规划的采伐水平是为了确保有足够的收成来支付必要的高密度森林的建设费用。
Forest managers need new approaches for maintaining high stand volumes while keeping forests continuously productive and economically profitable. The Silvicultural Management System (SMS) accomplishes these objectives by increasing large-sized trees for periodic harvest, and continuously maintaining stand volumes at their highest possible levels. This system takes advantage of the diversity in growth, vigor, and longevity of dominant trees from a wide range of tree species found in natural forest ecosystems. Under the SMS developed at the Tokyo University Forest in Hokkaido, 13–17% of the stand volume is harvested at a cutting cycle of 8–10 years by removing the oldest mature trees. Residual stand volumes are maintained at about 70–80% of the levels found in natural old-growth stands. This removal of the oldest trees keeps the stands in a continuously healthy and productive state. The cutting level is planned to ensure a sufficient harvest to cover the construction costs of a necessary high-density forest...
