武功山山地草甸土壤磷素分布格局及其与土壤酸度的关系
Spatial Distribution of Soil P And its Correlation with Soil Acidity in Mountain Meadow of Wugong Mountain
摘要
Abstract
Phosphorus is one of the essential elements for plant growth .Sites were set according to differ-ent altitudes ( the altitude range from 1 600-1 900 m) and different soil depths in the mountain meadow of Wugong Mountain in Jiangxi Province ,and the spatial distribution of soil total P content and the available P content,and the correlation between soil P and soil acidity were analyzed .The main research results were as follows:( 1) The cotents of soil available P and total P showed a law of vertical distribution .With the elevation increasing gradually ,the total P content and available P content increased gradually ,the ranges of variation in soil total P and available P were 3.71-17.78 mg/kg and 0.46-1.37 g/kg respectively.The available P content had spatial correlation with the total P content .( 2) There was no significant difference in pH along the altitudes and soil depths .The soil total hydrolytic acidity and soil exchangeable acidity increased significantly with the increase of altitude.(3)There was a significant positive correlation between soil available P and soil total hy-drolytic acidity and soil exchangeable acidity .This study revealed the spatial distribution of soil P and the cor-relation between available P and soil acidity ,providing a guidance for vegetation restoration in mountain mead-ow ecosystem .关键词
