摘要:
贵州西部地区是石漠化非常严重的地区,在喀斯特石漠化的大环境下,研究分析土壤氮磷特征对该区域生态恢复与治理石漠化有十分重要的意义.采集了贵州西部地区不同石漠化程度、不同利用方式的土壤样品,进行室内理化分析.结果表明:土壤有机质、全氮、全磷、速效磷含量总体较低,以无明显石漠化地区最高,随石漠化程度的加深而降低,但土壤有机质、全氮在极强度石漠化地区略有提高.在不同利用方式下,以林地土壤含量最高,随植被覆盖率的降低而降低,随垦殖率的提高而降低.
Abstract:
The west of Guizhou province is rocky and desertified.In karst rocky desertified area,analysis on soil nitrogen and phosphorus has certain significance in proving the ecology and restoring the rocky,deserted environment.With this background,the authors gathered soil in various degree of rocky,desertified areas and different use ways,then carried out physics and chemical analysis.The results show that,the quantity of soil organic matter,total N,total P and rapidly available phosphorus are low,and it is the highest in areas without obvious rocky desertification.The more obvious the rocky desertification degree is,the lower the quantity of soil organic matter,total N,total P and rapidly available phosphorus is.But the quantity of soil organic matter and total N are enhanced in the intensity rocky desertification area.Under the different use ways,the quantity of soil organic matter,total N and total P is the highest in the forest land soil,and it reduces along with the vegetation coverage fraction reduction and also it reduces along with the cultivation ratio enhancement.
