摘要
该文通过标准地调查与土样测定,分析了长白山北部林区云冷杉林下土壤的理化性质、营养元素含量、土壤酶活性、土壤微生物种类和数量,并与相同立地条件下的人工落叶松林进行对比.结果表明,长白山北部林区各类型云冷杉林下土壤理化性质、养分含量、土壤酶与土壤微生物数量相差不大,原始林稍高,人工落叶松林下土壤养分含量、土壤酶与土壤微生物数量相对云冷杉林较低.提出了保护与发展云冷杉林的措施.
Through sample plots' investigation and soil sampling analysis, the paper discusses spruce fir forests' soil physical and chemical properties, nutrient content, soil enzymes and soil microorganisms amount in north Changbai Mountains compared with soil under planted larch forest. The results show that there is no much difference on soil physical and chemical properties, nutrient content, soil enzymes and soil microorganism amount under different types of spruce fir forests in north Changbai Mountains. In all the spruce fir forests, the above mentioned indicators' quantity of primitive spruce fir forest is higher than those of other types. The soil nutrient content, soil enzymes and soil microorganism amount under planted larch forest are lower than those of spruce fir forests. In the end, the authors put forward some suggestions on protecting and developing spruce fir forests in this region.
