| 摘 要： | 于１９９０年在福建三明市小湖格氏栲自然保护区，对格氏栲天然林、格氏栲和楠木人工林的土壤肥力进行试验研究，采用标准地方法，其研究结果表明：结构多层次的格氏栲天然林林地自肥能力较强，具有良好自动调节及抗逆性能。格氏栲和楠木纯人工林，林分结构单一，凋落物层和表土层变薄，土壤结构性能变差（其中楠木林更为明显），土壤营养元素贮量锐减，土壤酶活性降低，土壤肥力下降，栽埴２３年后的格氏栲人工林的土壤肥力仍远低于

| Abstract: | Using the method of the position observation,the soil fertility of natural forest of Castanopsis Kawakamii, plantation of Castanopsis Kawakamii and Phoebe Boumei in Xiaohu,Sanming,Fujian, were studied in 1990 The results show that, the ability of soil self-fertility for the natural forest of Castanopsis Kamakamii are stronger, which has good performance of self-regulauon and resistant. The forest stand of the pure plantation of Castanopsis Kawakamii and phoebe Bourmei is single, the forest floor and surface soil layer thin out,the function of soil structure gets bad,the store of soil nutrient elements reduces sharply,the soil enzyme actitity and fertility decrease. Soil fertility of broadleaf planted for 23 years plantation is still lower than that of natural forest. It indicated that the soil fertility of which natural forest is disturbed would have long time to recover. |
