摘  要：
球囊霉素相关土壤蛋白(glomalin-related soil protein,GRSP)对土壤生产力的提高具有重要意义,已逐渐成为当前土壤养分研究的热点,然而GRSP与土壤理化性质之间空间相互关系则鲜见报道。本文以东北小兴安岭余脉老山、帽儿山、东山、大青川人工落叶松林土壤GRSP为研究对象,利用多变量协方差及共线性对土壤(0~80 cm)中GRSP与有机碳、全氮、全磷、全钾等12个土壤理化因子之间的空间差异特性进行分析。结果表明:(1)土层深度是造成GRSP含量及土壤各理化因子差异的因素之一;(2)逐步回归方法分别反映出EE-GRSP协同贡献最大因子为有机碳(β=0.312),而T-GRSP协同贡献最大因子为全磷(β=0.376),而容重则是两者共有的负相关因子(β=-0.229,-0.212);(3)GRSP垂直分布与土壤各理化因子的共线性分析中发现,GRSP与土壤全磷之间存在显著共线性(P<0.05)。本研究表明,GRSP与土壤理化性质之间存在显著空间异质性,充分印证了GRSP在土壤养分运输及可持续利用的重要作用,并且筛选出影响GRSP含量及与其生态功能相关土壤因子,为土壤质量及功能评价提供依据。

摘  要：
Glomalin-related soil protein( GRSP) plays an important role in enhancing soil productivity,and it has been one of the hot subjects in the soil nutrient research field. However,few studies have focused on the correlations between GRSP content and soil physicochemical properties. In this paper,soils from 0- 80 cm depths were collected in Larix gmelinii plantations in the Lesser Khingan( Laoshan,Mao'ershan,Dongshan,Daqingchuan) in Northeast China. Multiple covariances analysis and collinearity analysis were used to analyze the spatial correlations between GRSP content and soil physicochemical properties( soil organic carbon,total nitrogen,total phosphorus,total potassium,available nitrogen,available phosphorus,available potassium,soil Ca CO3,available silicon,soil p H,soil bulk density and electrical conductivity). The results showed that,( 1) soil depth was a key factor affecting the variations of GRSP content and soil physicochemical properties.( 2) soil organic carbon and total phosphorus respectively contributed most to EE-GRSP content( β = 0. 312) and T-GRSP content( β = 0. 376),and soil bulk density was a negative factor contributing most to EE-GRSP content and T-GRSP content( β =- 0. 229,- 0. 212).( 3) significant collinearity was observed between GRSP and total phosphorus( P < 0. 05). Our results showed that significant spatial heterogeneity was observed between GRSP content and soil physicochemical properties. These data suggested that GRSP had important effects on soil nutrient transportation and soil sustainable use. In addition,the soil factors which affected GRSP content and its ecological function were also identified. Our study provides a basis for assessing soil quality and soil function.
