摘要
林地土壤有机碳反映了林地土壤质量,直接影响着森林生态系统生产能力。本研究以秦岭马头滩林区不同龄组华山松为研究对象,分析了华山松林土壤和凋落物有机碳含量、密度及其影响因素。结果表明:华山松林土壤有机碳含量随林龄的增长总体呈上升趋势,随土层深度增加而减小;凋落物层有机碳含量随林龄的增长先增加后减小再增加。华山松林表层土壤有机碳密度随林龄的增长而增加。华山松林龄、乔木层生物量、胸高断面积、土壤容重和乔木层密度与土壤有机碳含量、密度呈显著相关关系。
Leisure agriculture in Chenggu was reviewed in terms of current situation,existing problems,locations,natural and humanitarian advantages.Based on that,suggestions and countermeasures were developed regarding,planning and designing,coordination of all aspects,systematic construction and composition of supply-chain.More efforts should be focused on brand strategy,excellence product innovation and broadening financial investment to drive new development of leisure agriculture.
