基于双哑变量模型预测透光抚育强度对次生林内红松生长的影响OA北大核心CSTPCDMEDLINE
Prediction of liberation cutting intensity effect on the growth of Korean pine in secondary forest based on double dummy variable model
"栽针保阔"是恢复我国东北阔叶红松林的有效途径,透光抚育能促进冠下红松生长并加快演替进程,但目前有关透光抚育如何影响次生林内红松生长过程仍不清楚.以长白山"栽针保阔"红松林为对象,构建含双哑变量(透光抚育强度和林木分级)的红松胸径和树高生长模型来预测不同透光抚育强度[即对照(未透光)、轻度透光抚育(保留上层郁闭度0.6)、中度透光抚育(0.4)、强度透光抚育(0.2)和全透光(伐除全部上层阔叶树)]林分中红松三级木的生长过程,揭示透光抚育强度对林…查看全部>>
"Planting conifer and reserving broadleaved tree"is an effective way to restore broad-leaved pine forest of temperate zone in Northeast China.Liberation cutting can promote the growth of Korean pine(Pinus koraiensis)under forest crown and accelerate the succession.However,how liberation cutting intensity affects the growth of Korean pine in secondary forest is still unclear.Taking the"Planting conifer and reserving broadleaved tree"Korean pine forest in Chan…查看全部>>
