【摘要】 本文以凤阳山黄山松林地为对象,对不同海拔土壤有机碳结构进行了研究。结果表明,海拔高度对黄山松林地各土壤活性有机碳含量均有一定的影响,随海拔升高,土壤总有机碳、水溶性有机碳、微生物量碳含量均表现出先增多后降低的趋势,最大值均出现在1500m处,而最小值出现在1700m处,但在1700m处水溶性有机碳和微生物量碳与总有机碳的比例值高于其他海拔。更多还原

【Abstract】 In this paper,we researched the Pinus Taiwanensis forest soil indifferent altitude of Feng yang Mountain in China.We analyzed the rules of soil organic carbon.The results show that:The factor of elevation impacted the all kinds of active soil organic carbon.The variation of the soil total organic carbon,dissolved organic carbon and microbial biomass carbon increased first,and decreased then with the elevation rose.It reached the maximum value and minimum value at the elevation of 1500 m and 1700 m,respectively.The ratio of sum of dissolved organic carbon and microbial biomass carbon to soil total organic carbon was higher than it of other elevation.更多还原
