摘要
利用湿地松人工林标准地材料,选择Korf方程并用免疫进化算法求解参数,分别立地质量建立林分蓄积量、平均胸径、平均高和株数等因子模型,按照变量间的函数关系及生长量、生长率的定义,编制了具有主林木的湿地松人工林经验收获表,为生长收获预估提供了定量依据。
Using Pinus elliottii plantation standard ground materials,selecting Korf equation,the parameter was solved with the immune evolutionary algorithm,the site quality was divided to build the stand stocking,average dbh,average height and trees number factor models,in accordance with the functional relationship between the variables and growth and growth rate definitions,Pinus elliottii plantation empirical harvest table was prepared,which provided a quantitative basis for the growth and harvest estimates.
