摘要：采用分布式测算方法,对河北、辽宁、湖北、湖南、云南和甘肃6个重点监测省份的退耕还林工程不同林种的生态效益进行了评估。结果表明,生态林的综合生态效益最好,经济林次之,灌木林最差。其中,在固碳释氧、营养物质积累、净化大气环境和生物多样性保护方面,生态林均优于经济林和灌木林,表现最好;在保育土壤方面,灌木林的效益最好;就涵养水源的效益而言,生态林则优于灌木林。
The ecological effects of ecological forest,economic forest and shrubbery in the project of con-version of cropland to forest of Hebei,Liaoning,Hubei,Hunan,Yunnan and Gansu provinces were as-sessed by using the distributed measurement method.The results show that the total ecological effect of ec-ological forest is the best,followed by that of forest and shrubbery which is the worst.The effect of ecologi-cal forest is the best for carbon fixation and oxygen release,nutrient accumulation,atmosphere environ-mental purification and biodiversity protection. The effect of shrubbery is the best for soil conservation.The effect of ecological forest is better than that of shrubbery for water conservation.
