为探究冰灾后城市森林不同植被恢复类型土壤微生物的演变特征,对长沙天际岭林场冰灾后3种恢复植被的栾树人工纯林、蕨草地、针阔混交林冬夏两季的土壤微生物数量、微生物活度、土壤理化性质及其相互关系进行了比较研究。结果表明,夏初不同植被恢复类型0-15cm土层土壤微生物活度以针阔混交林最高（0.302）,蕨草地次之（0.261）,栾树人工纯林最低（0.192）;3类植被中栾树人工纯林土壤冬季放线菌活力最弱,夏季细菌活力最弱;栾树人工纯林、针阔混交林土壤微生物生命活动冬季以真菌、细菌为主,夏季以真菌、放线菌为主,蕨草地无论冬夏土壤微生物活动都以真菌和细菌为主,放线菌活动较弱;在土壤微生物生...

To study the evolving soil microbial characteristics in restoring urban forest destroyed by ice storm,an investigation had been conducted in three vegetation restoration types（Koelreuteria paniculata pure forest,Hypolepis punctata rangeland,pine and broad leaf mixed forest） in Tianjiling forest centre,Changsha.The soil quantities of microbe,soil microbial activity,the physic-chemical characteristics in the soil,and among which relation for each vegetation restoration types were measured/calculated and compared.The results showed as followed.T...
