Clear-cutting and Root-sprout Regeneration Is An Efficient Way for Large-scale Reforming of Locust Forest

刺槐是我国中西部重要的水土保持林树种。由于滥伐和管理问题致使大面积的刺槐人工林虽有生态效益，但经济效益很低。经我们在长武王东沟试验区多年试验研究表明：皆伐萌蘖更新是改造低产值刺槐林的有效途径。

Locust is one of the main afforestion species of soil and water conservation in the mid-dle west of China,especially in the loess plateau. As the denudation and runaway,locust forestin a large scale area still have some ecologic benefit,but the economic benefit was lower. The re-sult of experments and researchs in Changwu conuty,Shaanxi province showed that clear-cuttingand root-sprout regeneration is an efficient way of reforming lower product locust forest.
