中文摘要	精河入湖口湿地是典型干旱区湖泊湿地艾比湖湿地的重要组成部分。本研究采用空间序列代替时间序列的方法分析了艾比湖精河入湖口退化湿地恢复中土壤呼吸的变化特征。结果表明:(1)随着恢复期的延长,土壤CO_2通量的日变化有由单峰型向双峰型转变的趋势;(2)恢复期较短的湿地(1 a),季节变化具有单峰型特点,峰值在秋季,恢复期较长的湿地(3~5 a),季节变化呈现双峰型,且春季高于秋季;(3)退化湿地在植被恢复过程中土壤呼吸速率逐渐增强;(4)在退化湿地的不同恢复阶段,近地面10 cm土壤温度与土壤CO2通量的关系最密切。因此,只要水源充足,精河入湖口退化湿地在恢复过程中土壤呼吸速率随恢复时间延长而逐渐提高,经4~5 a即可恢复到未退化状态。
英文摘要	The wetland of Jinghe River estuary is a main part of Ebnur Lake wetland.The soil respiration characters of degenerative wetland in this region were studied based on the method of space substituting time.The results indicated that:(1) The trend of diurnal soil respiration was changing from single peak to double peaks during the recovery time.(2) The character of soil respiration which was recovering in short time(only one year) was a single peak curve in autumn.Meanwhile,the character of soil respiration which was recovering in long time(3~5 years) was a double peak curve in spring and autumn.The value of soil respiration in spring was higher than it was in autumn.(3) The soil respiration rate was enhancing gradually along with the vegetation recoverying.(4) The air temperature of 10 cm near surface had close correlation to soil respiration in different recovery period.So the conclusion is that the soil respiration rate will go up along with the more longer recovery time if the sufficient water could be supplied in degenerative wetlandand.It is possible that the degenerative wetlandand will come back to the initial status if we can take effective measures.
