土壤是地球陆地上动植物赖以生存的基础之一。 为摸清不同林种森林土壤养分含量的差异, 野外采集测定台山市 131 个样点 0 ~ 30 cm 的表层土壤样本, 基于大尺度土壤采样实测数据分析结果表明:(1) 粤东沿海森林土壤养分整体表现为全氮、 全磷含量偏低, 有机碳含量处于中等水平, 全钾含量整体较高。 (2) 不同林种间全磷含量存在差异, 其中, 特种用途林显著高于用材林和防护林; 土壤全氮、 全钾、 有机碳含量在不同林种间差异不显著。 针对性的改善森林土壤养分, 能够有效改善局部土壤养分状况, 促进森林生态系统稳定健康发展。 |

Abstract: |
Soil is one of the foundations for the survival of plants and animals on earth??s land. By collecting 0-30 cm surface soil samples from 131 sampling sites in Taishan city and measuring soil nutrient content,
the differences in forest soil nutrient content in different forest species were analyzed based on the measured data
of large-scale soil sampling. The results showed that: (1) the total nitrogen and total phosphorus contents were
low, the organic carbon contents were medium, and the total potassium contents were high. (2) There were
differences in total phosphorus content among different species, among which the special use forest was significantly higher than timber forest and shelter forest; The contents of total nitrogen, total potassium and organic
carbon in soil were not significantly different among different forest species. Targeted improvement of forest soil
nutrients can effectively improve local soil nutrients and promote the stable and healthy development of forest ecosystems. |
