| 摘 要： | 通过对研究地黔南州林地土壤养分的定量分析探讨黔南地区林地土壤的养分状况及养分价值,旨为科学评价林地土壤养分价值,为科学营林、合理利用森林土壤资源提供依据。研究表明:不同的植被类型,土壤养分的含量不同;有林地土壤的养分含量明显高于无林地土壤;土壤养分总量针阔混交林高于阔叶林,阔叶林高于针叶林;林地土壤营养物质的总储量为7277.59万t,相当于14581.05万t标准化肥,价值为472.19亿元。

| Abstract: | This paper studied on the forest soil to analysis of the soil nutrient status and the value of assets,in order to provide the basis for scientific forest management, rational use of forest soil resources. Results showed that in different types of vegetation, the soil nutrient content was different;In wood land the soil nutrient content was significantly higher than the nonforest soil; the total soil nutrient was highest than other types in mixed coniferous broad--leaved forest; the total reserves of soil nutrient was 72,775,900 tons, which was equivalent to 145,810,500 tons of standard fertilizer, worthed 47. 219 billion yuan. |
