沿江丘陵区海拔高度与采矿活动对土壤碱解氮含量的影响
Effects of Altitude and Mining Activities on Alkali-hydrolyzable Nitrogen Content in Low Hill Lands along Yangtze River
摘要
Abstract
[Objective] The effects of hills elevation changes and mining activities on soil nitrogen content of the alkali-hydrolyzable nitrogen in hilly area of Digang Town were studied. [ Method] The distribution of nitrogen was studied in the sample area. Soil alkali-hydrolyzable nitrogen brought by altitude change and mining activities were contrasted. [ Result] With the increase of the altitude, soil alkali-hydrolyzable nitrogen content decreased. Under different land utilization, the contents of soil alkali-hydrolyzable nitrogen had big difference. Alkali-hydronitrogen in native soil along hilly area reached Ⅱ level, and that in mined and abandoned mines reached Ⅴ level. [ Conclusion ] Under different land utilization, there was a positive relationship between alkali-hydrolyzable nitrogen content and vegetation coverage in hilly area.关键词
