为改善粗放经营管理,而引进工程管理机制,把科学技术与工程管理相结合,按工程管理程序来管理营林,实行集约经营。造林成活率、造林面积保存率、适地适树率等造林指标,均比一般造林的高,树木生长量与一般造林的差异,达到极显著水平,并有明显的经济效益,与一般造林相比较,每年可增加经济收入56.36元/亩。
The percent of a survival, a preserved area and a survival of the fittest on the forestation, based on the method of an engineering manage procedure, were higher than that on 'typical' one, and the tree increment showed extremely a difference compared with 'typical' one, which yielded a distinct economic benefit amounting to 56.36 yuan/a per year.
