| 摘 要： | 对闽北山地坡位对湿地松生长和养分利用效率的影响进行了研究,结果表明:坡位对湿地松幼林的生长有显著影响,中坡和下坡湿地松的树高、胸径和单株材积显著大于上坡;不同坡位上湿地松幼林的林分生物量为下坡(9 522kg hm~(-2))中坡(7 137kg hm~(-2))上坡(6 266kg hm~(-2));不同坡位上湿地松对养分的利用效率不同,其中中坡对氮、磷的利用效率显著高于上坡和下坡,下坡对钾、钙、镁、铁的利用效率高于上坡和中坡。

| Abstract: | The effects of slope position on growth & nutrient-use-efficiency of Pinus elliottii in northern Fujian Province were studied.Result shows that the slope position have a significant effect on growth of Pinus elliottii young forest;tree height , DBH & individual volume (9 522 kg hm-2)> middle slope (7 137 kg hm-2)> uphill (6 266 kg hm-2).The nutrient-use-efficiency of Pinus elliottii at different slope positions is different.The nutrient-use-efficiency of Pinus elliottii on nitrogen and phosphorus at middle slope is significantly higher than that at upslope and downslope.The nutrient-use-efficiency of Pinus elliottii on potassium, calcium, magnesium & iron at downslope is higher than that at upslope and middle slope. |
