摘  要：
为了解凤凰县植烟土壤pH分布和变化特征,分析了2000年和2015年凤凰县植烟土壤pH的描述性统计特征、适宜性分布和成土母岩、乡镇的植烟土壤pH变化情况。结果表明:(1)2015年凤凰县植烟土壤pH平均值虽高于2000年,部分土壤酸化或碱化,但土壤pH值变化较大;(2)从2000年至2015年,植烟土壤pH在5.5~7.0间的适宜样本比例减少,pH小于4.5和大于7.5的样本比例增加;(3)板页岩发育的土壤较石灰岩发育的土壤容易酸化;(4)凤凰县部分乡镇的植烟土壤pH下降,有部分乡镇的植烟土壤pH在上升。

摘  要：
In order to understand the distribution and variation features of the tobacco-growing soil pH in Fenghuang county,the descriptive statistical characteristics,the suitability distribution and the soil-forming parent rock,the tobacco-growing soil pH as well as its transformation situation in towns from 2000 to 2015 were analyzed. The results were showed as follows:( 1) The average value of the tobacco-growing soil pH in 2015 was higher than that in 2000,a part of soil appeared acidification or basification,but the soil pH changed little.( 2) The samples proportion of tobacco-growing soil with suitable pH range 5. 5 to 7. 0 was decreased,and the sample proportion that the soil pH less than 4. 5 and higher than 7. 5 were increased from 2000 to 2015.( 3) Compared with the soil formed of limestone,the soil formed of shale was easier to be acidification.( 4) The tobacco-growing soil pH was declined in some towns,but the situation was the contrary in some other towns.
