立地条件与湿地松幼林树高生长关系

Study on the Relationship Between the Height of P elliottii Plantation and Site Condition

基于９年生湿地松人工林的５４个标准地立地条件与树高生长的调查，初步研究表明：湿地松生长受海拔高度影响最大，随海拔递升而下降；湿地松生长受地形影响，在山洼、山谷处生长最好，山坡、山顶、山脊则较差；湿地松生长受坡向影响较小．

Based on investigation into the site condition of 54 representative areas and the growth situation of 9 year old P elliottii plantation, the effect of site condition on the growth of P elliottii plantation had been studied in this paper The results showed that elevation and topography significantly affected the growth of P elliottii plantation, while other factors had no effect P elliottii plantation grows better on the lands with low elevation and low-land than on the high elevation, slope areas and ridges
