摘要
本文通过西营河试验区一次抚育的有关资料，对抚育伐的经济效果进行了分析，得出３３·３ｈａ试验地，以１０％的强度抚育，纯收入为人民币１８０，２７４元；一个龄级后，立木蓄积比未抚育情况下增长３４８２．７１０７ｍ３；计算出当前龄级抚育伐的森林学效率为４１．７６％、经济效率为２３９．４３％。
According to data of site harvesting of Xiying River experimental plots,the economic effect of tending felling is analyzed,It shows that bv cutting of intensity of 10%,the net inconle of 180274 RMB yuan is obtained,growing stock after one year is increased 3482.7107m3 than that of one year unte-nded felling in the 500 mu experimental plots.Forest efficeincy at present age1s 41.76%and econmic efficiency is 239.4s%. It has important significanceto solve inadequate funds on the management of water conservation forest.
