以“近自然林业”为指导思想，对凉水自然保护区早期做过林隙透光试验的红松人工林的土壤化学性质进行分析，同时与红松天然林、红松人工纯林、红松人工针阔叶混交林的土壤化学性质进行对比研究。结果表明：林隙透光抚育有利于提高土壤中各养分的质量分数，林隙透光试验地（土壤深度0＜H≤20cm）的水解氮、速效磷、速效钾、全氮和全磷的质量分数分别为640．28 mg· kg-1、7．54 mg· kg-1、275．91 mg· kg-1、1．114％和0．075％，与其他林分相比都是最高的，且为平均值的1．1、1．4、1．3、1．6、1．2倍；对于同一林分类型的红松林来说，不同层次的土壤养分存在着明显的差异，由0＜H≤20 cm到20 cm＜H≤40 cm，土壤各养分指标都呈现不同程度的下降趋势，其中，下降幅度最大的是有机质质量分数，下降了170．64％，下降幅度最小的是pH值，下降了4．66％。

With “close-to-nature forestry” theory, the experiment was conducted to analyze the soil chemical properties of Kore-an pine ( Pinus koraiensis) plantation forest by crevice diaphanous tending experiment in Liangshui Nature Reserve and compare the results with those of nature Korean pine forest, artificial pure Korean pine forest, Korean pine planatation and the broadleaved mixed forest.The nurture of forestry crevice diaphanous tending can improve the soil nutrient contents and significant differences of soil nutrients in different levels of soil for the same forest type of Korean pine.At 0<H ≤20 cm layer, the contents of available nitrogen, available phosphorus, available potassium, total nitrogen and total phosphorus in artificial pure Korean pine forest are 640.28 mg· kg-1 , 7.54 mg· kg-1 , 275.91 mg· kg-1 , 1.114% and 0.075%,re -spectively , and they are all higher than those of the other kinds of forests, and 1.1, 1.4, 1.3, 1.6 and 1.2 times than the averages.In 0<H≤20 cm and 20 cm<H≤40 cm layers, soil nutrient indicators show decreasing trend.The organic matter declines sharply by 170.64%, while pH declines slowly by 4.66%.
