不同地貌杉木人工林胸径树高生长曲线研究
|
摘要
为准确掌握景宁县杉木人工林的生长情况,采用4种生长方程分别拟合杉木胸径树高生长情况,并选择最优生长模型。研究结果表明:多项式方程能够较好的拟合景宁地区杉木林的生长情况,平均决定系数高达0.889;地形因子对杉木生长具有重大影响。
In order to accurately grasp the growth of Chinese fir plantation in Jingning County, four growth equations were used to fit the height growth of Chinese fir with DBH, and the optimal growth model was selected. The results show that the polynomial equation can better fit the growth of Chinese fir forests in Jingning area, with an average determinant coefficient of 0.889; topographic factors have a significant impact on the growth of Chinese fir.
