文章对桂林会仙湿地在受不同强度人为活动干扰情况下土壤有机质空间分布特征进行研究,结果显示:会仙湿地土壤有机质水平空间分异为原生湿地>垦后湿地>退化湿地>非湿地;垂直空间分异差异显著,表现出表层土有机质含量均比下层土有机质含量高;土壤退化指数定量反映了在不同强度人为干扰情况下湿地土壤有机质的退化程度,即原生沼泽退化程度随人为活动干扰强度加剧而加深。 The spatial distribution characteristics of soil organic matter in Guixian wetland under the interference of human activities with different intensities were studied. The results showed that: the spatial heterogeneity of soil organic matter in Huixian wetland was from primary wetland to reclaimed wetland to degraded wetland to non- The spatial heterogeneity is significant, showing that the content of organic matter in surface soil is higher than the content of organic matter in lower soil. The index of soil degradation quantitatively reflects the degree of degradation of organic matter in the wetland under the condition of different intensity man-made interferences, Intensified and deepened.
