| 摘 要： | 对千烟洲试验区湿地松人工降雨后，20种矿质元素淋溶变化变化进行了研究，结果表明：湿地松人工林中的营养元素平均浓度总变化趋势是：林冠穿透水＞树干流>大气降水。在淋溶成分中，林冠穿透水对湿地松人工林的养分物质年贡献较大，占整个淋溶总量70%以上。

| Abstract: | This paper studies the leaching changes of the 20 nutrient elements in the artificial splash pine forest after rainfall events at Qianyanzhou Experimental Station.The results show that the total change trend concentration of nutrient elements is crown throughfall>stemflow>rainfall in the artificial splash pine forests.The annual contribution of throughfall is larger than others for nutrient elements in the artificial splash pine forests,which occupy over 71% of the total leaching process. |
