摘要:
 为了解冀北坝上地区樟子松人工林的土壤条件及其与生长的关系，采用典型取样方法对塞罕坝机械林场樟子松林的土壤进行了研究。结果表明，不同立地樟子松林的土壤养分含量有明显不同，各养分元素均以坝上山地壤质土和坝下山地壤质土为最高，坝上西部曼甸砂质土和坝下平地壤质土最低；坝上和坝下地区土壤养分含量总体上较为接近，但是坝下地区不同林地之间土壤养分含量的差异明显>坝上地区。樟子松林土壤中全氮、水解氮、全磷、速效磷、全钾、速效钾的含量均随有机质的增加而增加，而且具有明显的回归关系，但回归关系的形式各不同，可基于回归关系通过有机质含量来估测其他土壤养分元素的含量。樟子松优势木树高与土壤养分含量之间没有表现出明显的正相关关系，但与土壤厚度有正的相关关系，樟子松适宜土层深厚的立地条件，而对土壤养分含量要求不高。
Abstract:
 In order to understand the soil nutrients of Pinus sylvestris var.mongolica in northern Bashang (upper dam) aera of Hebei Province and the relationship between the soil nutrient conditions and the growth,typical sampling method was adopted.The main results were as follows.There were distinct differences in contents of nutrient elements among different forests in different sites,the highest content was found in loamy soil in the upper dam mountain and loamy soil in the down dam mountain,and the lowest was in sandy soil in upper dam western Mandian and in loamy soil in the flat land under dam.The contents of soil nutrients on the dam area were generally close to that of under dam,but the differences of the soil nutrient contents in different forest areas under dam were obviously greater than that on the dam area.The contents of total N avilable N,total P,available P,total K,available K in the soil increased with the increase of organic matter,and there was a close regression relationship between them.However,the form of the regression relationship was different.On the basis of regression relation,the contents of other soil nutrients were estimated by organic matter.It did not show a significant positive correlation between the dominant tree height and the contents of the soil nutrient,but there was a positive correlation between dominant height and soil thickness.In summary,P.sylvestris var.mongolica was suitable to grow in deep soil site,but the requirement for soil nutrient content was not high.
