LIU Chang-xiu1,ZHANG Hong1,ZE Bai2,LUO Guang-rong2(1.Center of Resources and Environment,Sichuan Normal University,Chengdu 610066,China; 2.Sichuan Grassland Science Academy,Hongyuan 624400,China)  
A Alpine shrubland was selected as the study site,and by pane sampling,random ly sampling 50 soil samples in 0~20cm of the Alpine shrubland,noting detailed its living surroundings of each soil sample of shrubland according to under shrubs and between shrubs in study area in Hongyuan county of the northwestern plateau of Sichuan province,and analyzing the characters of these soil samples.These experimental data have been analyzed and compared by the SPSS(11.0),and the mean concentration,spacial heterogeneity and correlation of each soil nutrient were studied.Results indicated that the main soil nutrient is no significant difference except that Ntotal of soil under shrubs is notable more than that between shrubs in the two living surroundings of shrubland.Each soil nutrient coefficient of variation(CV)of two diminutive entironment is middle variation,the other CVs of soil under shrubs is bigger than that between shrubs except for Ptotal?Pavail.There are also significant correlation and very significant correlation between Pavail and Kavail,C/N and Ntotal,C/N and organic matter in two living conditions.There are sinificant linearity correlation between pH and C/N,pH and organic matter of soil between shrubs,but Pavail and Kavail,Pavail and Ntotal of soil under shrubs have significant linearity correlaton.Totally,the soil's main nutrient N,P,K have better correlation under the shrubs.It showed that the main soil nutrient such as N,P,K are translating and affecting each other,and the relation is more osculation under shrubs,and that shrubs have effect on the space distributing of soil resources in Alpine shrub meadow.
