不同坡位油松林土壤微环境及生长变化研究

Study on Soil Microenvironment and Growth of Pinus tabulaeformis Forest on Different Slope Position

对辽西地区不同坡位的油松林土壤微环境及生长量开展了比较研究。结果表明:随着坡位的增高,表层土壤温度有所增加,含水量和土壤容重有所降低。树高增长量以上坡为最大,其次是中坡,下坡生长量最低。

The soil microenvironment and growth of Pinus tabulaeformis forest on different slope positions in western Liaoning province were studied,through comparative analysis,the results showed that as the slope level increased,the surface soil temperature increased,and the water content and soil bulk density decreased.The tree height growth was the highest on the upper slope,followed by the middle slope,and the lowest growth on the lower slope.
