中文摘要：
通过15个剖面样品分析，对金佛山北坡土壤酸度分布特点及影响因素进行了研究。结果表明，金佛山地区土壤酸度分布呈现pH平均值偏低、变异较大的特点：山腰志留系砂页岩区土壤酸度大干灰岩区的土壤酸度；在石灰岩区，山顶的土壤酸度则比坡腰和山脚的大，缓坡地带的土壤酸度比陡坡地带的大。山腰和坡脚pH值较高，体现了植被状况和人类干扰的共同影响，而页岩区土壤酸度较灰岩的大，则反映了成壤母质的影响作用。
英文摘要：
The distribution of soil acidity and the influencing factors on the north slope of Jinfo Mountain were studied in this paper according to the analytical data of on 15 samples. The results show that the distribution of soil acidity in this area exhibits a character of mean pH value lower than that in the other regions, and the soil acidity varies intensely in the area. Soil acidity in this area is mainly influenced by lithology, landform and physiognomy, vegetation and human activity. Stratum and lithology are important factors that affect soil acidity in Jinfo Mountain. Soil acidity in sandstone and shale region of the Silurian stratum along the mountainside is bigger than that in limestone region at the top and the foot. In karst region, soil acidity on gentle slope is higher than that on steep slope within the mountaintop area. The high pH value on the mountainside and foot shows the impact of vegetation condition and human activity, and the high soil acidity reflects the impact of soil parent materials.
