Succession Dynamics of Larix principis-rupprechtii Plantation in Intermediate Section of Qinling Mountains
In this paper,we investigated the succession tendency of 18-48-year-old Larix principis-rupprechtii plantations in mid-low altitude and mid-high altitude districts,and proposed the corresponding management strategies.The results showed that:the succession tendency of L.principis-rupprechtii plantations in mid-low altitude district would be the pure L.principis-rupprechtii forests→ mixed broadleaf-conifer forests of L.principis-rupprechtii + Quercus aliena var.acuteserrata + Acer davidii + Juglans cathayensis + Toxicodendron vernicifluum→ mixed broadleaf-conifer climax communities of Quercus aliena var.acuteserrata + Juglans cathayensis + Toxicodendron verniciflum.The management strategy paid equal attention to economic benefit and ecological benefit,The close-to-nature forest management technology was used to build the different age,stratified mixed forests in which L.principis-rupprechtii was dominant species and Quercus aliena var.acuteserrata + Juglans cathayensis + Toxicodendron vernicifluum were associated species.The succession tendency of L.principis-rupprechtii plantations in mid-high altitude district would be the pure L.principisrupprechtii forests→mixed broadleaf-conifer forests of L.principis-rupprechtii + Pinus armandi + Betula albo-sinensis→ mixed broadleaf-conifer forests of Pinus armandi + Betula albo-sinensis + Pinus asperata (Picea wilsonii) or Abies fargesii→climax communities of Pinus asperata (Picea wilsonii) or Abiesfargesii.In this district,the management strategy should consider tree species conversion,follow natural succession trend,and speed up its succession process to climax through human intervention communities of Pinus asperata(Picea wilsonii) or Abies fargesii.
