摘要
收集288块马尾松人工林标准地材料,以密度二次效应模型为基础,用连续状态的动态规划方法建立可变间伐间隔期的林分经营密度模型。模拟结果表明该模型反映了马尾松人工林林分的密度动态,符合林分生长的一般规律,可为抚育间伐等提供科学依据。
Based on the 288 standard plots' data of pinus massoniana plantation and the double effect density model,a forest management density model of variable shinning's interval was built up by using the method of seccessive dynamic programme.The simulated results show that the model itself reflects the trends which tally with the general growing law and therefore provides a scientific basis for the guide of management measure such as tending thinning.
