Based on investigation data and reference to other stands data in the similar environment,FDT of Pinus caribaea in Baisha County,Hainan Province was designed. Accordidng to the condition of forest stand,it was the object to transform pure coniferous stand to close to nature stand with the structure of coniferous broadleafed mixed forest. On the other hand,visualization of FDT by LMS(landscape management system),was performed for management Pinus caribaea in future.展开更多
