徐州市城区绿地土壤碳储量格局及养分特征
The Pattern of Carbon Storage and Nutrient Characteristics of the Soil in the Greenbelt in Xuzhou City
摘要
Abstract
Soil carbon storage and its distribution pattern are of great significance to understand relationship between the vegetation in greenbelt of city and soil and to promote ecological city construction and guarantee sustainable development of urban.Soil carbon storage pattern and soil nutrient characteristics of greenbelt of urban in Xuzhou City were analyzed by integrating the data for both the large city scale and soil sample scale.The results show that：（1） soil pH value in greenbelt of urban is generally alkaline or weak alkali（pH 7.8～8.3）,average level of soil organic matter content is low;（2） in the same soil depth,there is weak alkaline in soil of greenbelt with the longer duration,which is obviously negatively relevant to soil organic carbon content;（3） soil carbon density and carbon storage in 0—60 cm soil depth decrease with increase of the soil depth;（4） soil organic carbon content is also showing gradually decreasing trend with the increase of the depth of soil.关键词
