刺槐生长量的灰色预测

The Gray System Prediction of Locust Yield

通过对刺槐树高、胸径连年生长量的灰色预测ＧＭ（１，１）模型的建立，提出长武王东试区刺槐人工林应采取早期利用，以培育小径材为目标的经营原则，以提高刺槐林的经济效益。一般最经济的采伐树龄为１４～１８年。

Based on the building of gray system prediction model for locust current annual incre-ment of high and breast diameter,we advanced a managerial principle for the artifical locust for-est in Changwu agri-ecology experimental station,that we should use the forest as its early stageand take fostering small pole as the objective,so as to raise the economic benefit of locust forest. In the general terms,the most economic cutting age is 14～18 years.
