利用Sloboda多形指数曲线方程拟合了晋西方山县和吉县刺槐人工林的高生长模型。结果表明,模型在95%显著水平上通过检验,可用于试验区人工林收获预估和立地质量评价。将试验区坡向、坡位和部分地形按照优势木的高生长量由大到小的排序为:阳坡下部、阳坡凹地、阴坡中部、阳坡中部、半阴坡上部、阳坡上部、半阳坡中部、阴坡上部、峁顶、阳沟坡、半阳坡上部。 The Sloboda polymorphic curve equation was used to fit the high growth model of Robinia pseudoacacia plantation in Fangshan County, Shanxi Province. The results showed that the model passed the test at a significant level of 95% and could be used for plantation harvest prediction and site quality evaluation in the experimental area. The order of descending slope, sunny slope, central shady slope, middle sunny slope, upper semi-shady slope, upper sunny slope, , The middle of the mid-Yang slope, the upper part of the shady slope, the top of the ridge, the Yanggou slope and the upper part of the half-Yang slope.
