摘要/Abstract

摘要： 以白梭梭荒漠和盐生假木贼荒漠为对象,采用野外调查取样法,通过对两类不同类型荒漠草地土壤营养成分的测定分析,探讨不同类型荒漠草地土壤营养成分对短期封育的响应规律,为荒漠草地的管理和保护提供科学依据。结果表明:1)盐生假木贼荒漠草地的土壤营养成分含量显著高于白梭梭荒漠草地;2)短期封育对盐生假木贼荒漠草地土壤系统的碳密度、全氮、全磷和全钾含量的影响较小(P>0.05);3)短期封育下,白梭梭荒漠草地土壤碳密度增加了43.46%(P>0.05),但全磷和全钾分别降低了33.53%(P<0.05)和60.30%(P<0.05)。综上所述,短期封育对盐生假木贼荒漠影响较小,而对白梭梭荒漠草地土壤碳密度的积累有利;同时,导致白梭梭荒漠草地土壤全磷和全钾含量有下降趋势,表明封育效果与荒漠植被类型和土壤类型之间存在密切的关系。

Abstract: This research aims to clarify the effects of un-grazing (UG) on the nutrients composition of soil in Anabasis salsa desert (6 years of enclosure) and Haloxylon persicum desert (7 years of enclosure) and use the method of combination field survey with the laboratory analysis and studied the response of desert the nutrients composition of soil, which provide a scientific basis and management for the local animal husbandry. The results showed that: 1) The soil nutrient concentrations in A. salsa desert were significantly higher than in the H. persicum desert. 2) In A. salsa desert, short-term grazing exclusion (GE) had little effect on the carbon density, total N, total P and total K of the soil system. 3) In H. persicum desert, the carbon density increased by 43.46% (P>0.05) with GE, but total P and total K were decreased by 33.53% (P<0.05) and 60.30% (P<0.05), respectively. In summary, short-term GE has a small effect on soil properties in A. salsa desert, and promoted increased soil carbon density in H. persicum desert, but led to a decline in the total P and total K in H. persicum desert. The results showed that the GE effect differs between desert vegetation types and soil types.
