的林地土壤重金属 As 含量空间变异，对于城市的可持续发展具有重要意义。文章以韶关不同 GDP 的 5
个区（县）林地土壤为研究对象，测定 547 个林分样点的土壤重金属 As 含量。结果显示 5 个区（县）林
地土壤 As 含量接近污染警戒线，但处于尚清洁状态；林地土壤 As 含量随 GDP 的上升呈对数增长模式；
高 GDP 地区林地土壤 As 含量高于中、低 GDP 地区的林地土壤 As 含量，且其含量受人类活动和第二、

| Abstract: |
| Urban development and human activities can affect soil quality and heavy metal pollution degree
of forestland. It is of great significance for sustainable urban development to explore the spatial variation of heavy
metal As content in forestland soil in different areas of GDP. In this paper, the contents of heavy metal As in the
soil of 547 forest stand samples were determined in five districts (counties) with different GDP in Shaoguan. The
results showed that the As content of forest soil in five districts (counties) was close to the pollution warning line,
but still in the clean state. As content in forest soil increased logarithmically with the increase of GDP. Soil As
content in high GDP area was higher than that in medium and low GDP area, and its content was significantly
affected by human activities and secondary and tertiary industries. |
