【摘要】 对油松林、阔叶混交林、辽东栎3种不同植被的土壤碳、全氮、氨态氮及硝态氮含量进行分析研究。结果发现: 3种植被类型的土壤碳、全氮、氨态氮和硝态氮含量从6 月初至7 月中、下旬变化平稳; 7 月下旬到9月上旬变化剧烈; 9月中、下旬到10月下旬变化不大。不同植被对土壤中有机碳、全氮、氨态氮和硝态氮含量的影响有差异。更多还原

【Abstract】 In the current, the greenhouse effect and the rich alimentation in water have became an important problem in the study of global environment change, the contents of carbon and nitrogen in soil are important factors.The contents of carbon, complete nitrogen, ammonia nitrogen and nitrates nitrogen of oil pine forest, broad-leaved forest and Liaodong robur forest were analyzed.The result indicated that the contents of carbon, complete nitrogen, ammonia nitrogen and nitrates nitrogen of soil’s in three kinds of forest almost unchanged from the beginning of June to the middle of July and became acuity from the end of July to September, the change from September October became light.Different types of forests had different effect on the contents of carbon, complete nitrogen, ammonia nitrogen and nitrates nitrogen in soil.更多还原
