- [目的]明晰各植物群落土壤有机碳含量,以期为草原保护提供理论依据。[方法]以希拉穆仁荒漠草原围封区6种植物群落(短花针茅、洽草、羊草、克氏针茅、银灰旋花、蒙古韭)为研究对象,对0—30 cm土层各植物群落土壤机械组成、土壤有机碳含量和根系特征进行研究。[结果](1)6种植物群落0—30 cm土层土壤机械组成主要以粉粒和极细砂为主,其平均值分别介于26.50%～54.62%和16.90%～34.08%。(2)6种植物群落根系生物量随土层深度逐渐减小,且根系生物量总量介于229.21～731.71 g/m2。由根系分布特征判断,短花针茅群落各土层根系呈“E”型分布,其他植物群落均呈“V”型分布。(3)各植物群落土壤有机碳含量随土层深度逐渐降低。0—30 cm平均有机碳含量介于6.07～11.75 g/kg。(4)根系生物量、土壤有机碳含量与黏粒含量呈极显著正相关,与粉粒含量呈显著正相关,表明土壤粉粒、黏粒含量越多,植物群落根系生物量和土壤有机碳越丰富。[结论]围封可以有效促使土壤有机碳增加,但有机碳对不同植被群落的响应有所差异,草原有机碳储量准确度应根据草原植被群落特征而定。
- Abstract:
- The aims of this study are To clarify soil organic carbon content of each plant community and to provide a theoretical basis for grassland conservation. [Methods]Six plant communities(Stipa breviflora, Koeleria cristata, Leymus chinensis, Stipa krylovii, Convolvulus ammannii, Allium mongolicum)in the enclosed area of Xilamuren Desert Grassland were studied for soil mechanical composition, soil organic carbon content and root characteristics of different plant communities.[Results](1)The soil mechanical composition of soil depth of 0—30 cm in six plant communities was mainly composed of silt and extremely fine sand, with the average values of 26.50%～54.62% and 16.90%～34.08%, respectively.(2)The root biomass of six plant communities gradually decreased with soil depth, and the total root biomass was between 229.21 and 731.71 g/m2. Judging from characteristics of root distribution, the root distribution of Stipa breviflora was ‘E' type distribution, and the root distributions other plant communities were ‘V' type distribution.(3)Soil organic carbon content of six plant communities gradually decreased with soil depth. The average organic carbon content in 0—30 cm ranged from 6.07 to 11.75 g/kg.(4)There was a significant positive correlation between root biomass, soil organic carbon and clay, and a significant positive correlation with silt, indicating that the more soil particles and clay content, the richer the root biomass and soil organic carbon of different plant communities. [Conclusion] Enclosure could effectively promote the increase of soil organic carbon, but organic carbon varied in response to different vegetation communities. The accuracy of grassland organic carbon storage should be determined according to the characteristics of grassland vegetation communities.
