艾比湖湿地不同植被覆盖下土壤碳蓄积对比分析
The Ebinur Lake wetland soil carbon accumulation analysis under different vegetation types
摘要
Abstract
This research take in wetland soil covered by two different plants in the Ebinur Lake as the research ob-ject.By the ways field sampling and laboratory analysis,we tested the soil covered by desert shrubs and microphanero-phytes desert shrubs and calculated the carbon stock volume in 5 different soil layers.The results show that the soil car-bon content in microphanerophytes desert is 19.44 g·kg-1which is much higher than that in shrub desert,the maximum content of carbon in the shrub desert.The peak organic carbon content occurs in the soil's surface layer(0~20 cm), and the maximum organic carbon density also is presented in the soil's surface layer(0~20 cm).Soil in shrubs desert is 2.48 kg·m-2,soil in microphanerophytes desert is 6.37 kg·m-2.The calculation of soil accumulate stock volume of or-ganic carbon show that the carbon accumulation,soil in desert shrubs is 344 856.23 kg,and which is 3 743 517.41 kg in microphanerophytes desert.Soil carbon acumulationed ability in the microphanerophytes desert is higher than the shrub desert.This research can provide scientific reference for soil carbon cycle in arid wetland region and ecological restoration of Ebinur lake.关键词
