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。

Abstract: The ecological effects of ecological forest,economic forest and shrubbery in the project of conversion of cropland to forest of Hebei,Liaoning,Hubei,Hunan,Yunnan and Gansu provinces were assessed by using the distributed measurement method.The results show that the total ecological effect of ecological forest is the best,followed by that of forest and shrubbery which is the worst.The effect of ecological forest is the best for carbon fixation and oxygen release,nutrient accumulation,atmosphere environmental 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.

Key words: the project of conversion of cropland to forest, ecological forest, economic forest, shrubbery, ecological effects
