| 摘 要： | 对皖西大别山区3种森林植被类型土壤呼吸数据进行统计分析,结果表明:3种植被类型土壤呼吸随时间呈先升高后降低的变化趋势;土壤呼吸速率与地下5 cm、10 cm的土壤温度有较好的相关性;杉木林土壤呼吸与5～10 cm土层有机质呈极显著相关,相关系数为0.978(p＜0.01);麻栎林土壤呼吸与0～5 cm土层有机质呈显著相关,相关系数为0.928(p＜0.05);杉木麻栎混交林土壤呼吸与5～10 cm土层有机质呈显著相关,相关系数为0.964(p＜0.05).

| Abstract: | The data of soil respiration of three forests in Dabie Mountains in west Anhui was statistically analyzed.The results show that the daily changes of the soil respiration rate in the three forests increase first then decrease,and the soil respiration rate is correlating with the soil temperature at depth of 5 cm and 10 cm.In 5 cm to 10 cm depth of Chinese-fir forest,the soil respiration and the soil organic matter correlate very significantly with correlation coefficient 0.978(p<0.01),which is significant in... |
