为深入了解本园不同立地类型土壤养分状况，为公园植被优化和管理提供科学依据；对银瓶山森林公园采用样地调查法开展植物种类、土壤养分调查和测试分析。结果表明：（1）清溪景区入口景观、九洞景区防汛应急通道景观、九洞景区森林游憩地、谢岗圆墩背4个区域的改造地块与对照地块pH值均值均小于7，不存在显著差异；（2）九洞景区防汛应急通道景观改造地块与对照地块的有机碳存在显著差异，其他区域两者差异不显著；九洞景区防汛应急通道景观改造地块与对照地块的全氮存在显著差异；其他3个区域的全氮差异不显著；（3）4个区域的改造地块与对照地块全磷、速效磷差异不显著；九洞景区防汛应急通道景观和九洞景区森林游憩地全钾、速效钾均存在显著差异；其他两个区域差异不显著。

Abstract: |
|
Plant species and soil nutrient was analyzed based on sample site survey method in Yinpingshan Forest Park, Dongguan city, in order to deeply understand the soil nutrient status of different site types and provide a scientific basis for park vegetation and management optimization . The results show that: (1) The average pH value of both modified plot and control plot were less than 7 and was no significant in the four areas including the entrance of Qingxi scenic, emergency channel for flood prevention of Jiudong scenic, forest recreation area of Jiudong scenic and Xiegang Yuandunbei.(2) Organic carbon content between the 体育博彩平台排名ation plot and control plot in the emergency channel for flood prevention of Jiudong scenic showed significantly different and had no marked difference in other regions.The total nitrogen between the emergency channel for flood prevention of landscape reconstruction plot and the control plot in Jiudong scenic were significantly different; the total nitrogen were similiar in the other three regions.(3) The total phosphorus and available phosphorus content of the modified and control plots showed no significant difference in the four regions. The total potassium and available potassium content were significantly different in the emergency channel for flood prevention of Jiudong scenic and the forest recreation area of Jiudong scenic; the other two regions were not significantly different.
