| 摘 要： | 在我国北方农牧交错带,研究了不同土地利用方式对土壤质量的影响.结果表明,天然草地和过牧草地土壤全氮、总有机碳和全磷含量整体高于耕地和林间草地,退耕地种草后土壤全氮、总有机碳含量增加,全磷含量无显著变化.耕地和过牧草地土壤速效磷含量高于其他土地利用方式.天然草地、过牧草地和耕地土壤pH值显著高于林间草地和人工草地,而土壤电导率均为过牧草地显著高于天然草地,天然草地显著高于林间草地、人工草地和耕地.林间草地和过牧草地土壤容重显著高于天然草地和耕地,而天然草地土壤含水量显著高于其它土地利用方式,林间草地土壤含水量最低.

| Abstract: | The effect of land use conversion on soil qualities was studied in the agro-pastoral transitional zone in North China.The results showed that the contents of total nitrogen,total organic carbon and total phosphorus in soil of natural steppes and over-grazed steppes were higher than those of cultivated land and grassland openings.Land use conversion from cultivated land to perennial artificial grassland increased soil total nitrogen and total organic carbon but had no marked influence on total phosphorus.Ava... |
