摘  要：
为给岩溶山区土地合理开发利用提供参考,以贵州高海拔山区草地建植为研究对象,探讨天然草地建植为人工草地对土壤质量的影响。结果表明:天然草地建植为人工草地20余年后,土壤体积质量、毛管持水力、pH、全氮、碱解氮、速效磷和速效钾含量明显得到改善;土壤有效态铁、铜、锌和硼密度显著下降,最小降幅分别为79.43%、34.69%、57.45%和40.63%;有效态锰密度则平均增高47.92%。且2种不同植被类型的人工草地间土壤毛管持水力、全盐、全氮、碱解氮、速效磷、速效钾以及有效态微量元素密度也存在明显差异,说明在同一管理利用水平下不同植被类型对土壤质量的影响存在差异。

摘  要：
The effects of artificial pasture from natural grassland establishment on soil quality was studied in high-elevation mountain area to provide a reference for land rational development and utilization in Karst area.The results showed that soil volume mass,capillary water holding capacity,pH and total nitrogen,available nitrogen,available P and available K content of artificial pasture from natural grassland establishment is improved.The density of effective Fe,effective Cu,effective Zn and effective B decreases significantly and the minimum decrease range of effective Fe,effective Cu,effective Zn and effective B is79.43%,34.69%,57.45% and 40.63% separately but the effective Mn density increases by 47.92%averagely.There are significant differences in soil capillary water holding capacity,total salt,total nitrogen,available N,available P,available K and effective microelement density between two artificial pastures with different vegetation type,which indicates that different vegetation type has the different effect on soil quality under the same management and utilization level.
