检查法是一种适合于异龄林经营的集约作业方法。由于目前试验时间还较短（第１择伐周期１９８７—１９９２年），需要对其长期经营效果作出预测。文中提出了一种修正参数预测模型（ＭＰＰＭ）和线性规划方法相结合对于林分进行生长预测和择伐模拟研究的方法。拟合林分直径分布采用了形状灵活的Ｗｅｉｂｕｌｌ分布形式，使得这种方法很适合于异龄林分（反Ｊ形直径分布）的生长预测（当然也适于同龄林），特别是当径阶株数出现突然变化时，该方法更是表现出了很大的优越性。对吉林省汪清林业局检查法试验林分的择伐模拟和生长预测的结果表明，在长期实施采伐量低于林分生长量的低强度择伐作业（择伐周期５年）的情况下，试验林分既能保持稳定的木材收获，又能使林分蓄积量持续稳定增长。
Inspection method is an intensive operation method suitable for the management of different age forests. Due to the short duration of the test (Selective Logging Cycle 1987-1992), the long-term operating results need to be predicted. In this paper, a method of combining MPPM with linear programming is proposed to study the growth prediction and selective cutting of stands. The fitting distribution of the diameter distribution of the forest uses a flexible shape Weibull distribution, making this method very suitable for the growth prediction (anti-J-shaped diameter distribution) (also suitable for the same age forest, of course), especially when the diameter The number of strains in a sudden change, the method has shown great superiority. The result of simulating selection and growth prediction of the test forest in Wangqing Forestry Bureau of Jilin Province shows that under the condition of low-intensity selective cutting (the selective cutting period is 5 years) that the cutting amount is lower than the stand growth in the long-term, The test stands can not only maintain a stable harvest of timber, but also make the volume of stand stand a steady and steady growth.
