| 摘 要： | 对针阔混交林土壤理化性质的研究表明，针阔混交林比针叶树纯林对土壤的改良作用要好，它使土壤总孔隙度增加２—１９％，水分含量增加６—３１％，枯枝落叶年凋落量增加２—２００％；土壤养分含量全Ｎ、ＮＨ４－Ｎ、代换性Ｃａ、代换性Ｍｇ和腐殖质含量分别增加４５—７５％、３３—８２％、５５—８５％、４４—８４％和３７—４６％．

| Abstract: | Studies on soil physical and chemical properties of mixed broadleaved and coniferous forests show that the improvement effect of mixed forest on soil is better than that of pure forest, under which,soil porosity is increased by 2-19%,soil moisture content by 6-31%,annual litter amount by 2-200%,total N by 45-75 %,NH4-N by 33-82%,exchangeable Ca and Mg by 55-85% and 44-84% respectively,and humus content by 37-46%. |
