Abstract:
In order to investigate the distribution characteristics of soil nutrient under the ‘fertile island’ effect in Nebkhas vegetation，the article took the desert shrub Nitraria in Eastern Ningxia as the object of study and the research was concentrated on sand in different habitats and different soil pH，total salt and content of carbon，nitrogen and phosphorus and ecological stoichiometry characteristics.The results showed that pH and total salt were increased with soil depth，the increasing of the content of salt was more significant (P<0.05) relative to pH，with the increasing of the soil depth，soil organic carbon(SOC)，total nitrogen(TN) and total phosphorus(TP) decreased generally，in the surface of soil(0-40 cm)，the soil nutrient content 3 types of habitats：the crown margin between shrubs under canopy>periphery>interspace，TP relative to SOC and TN in different habitats，different soil layers did not change significantly(P>0.05)；in the surface soil of 0-20 cm，sand under canopy soil carbon to nitrogen(C/N)，carbon to phosphorus(C/P) and nitrogen to phosphorus(N/P) were increase significantly；from 3 different habitats from plants the nitratria nebkha，C/N，C/P and N/P had no obvious regularity，the classical difference analysis showed that，the effects of soil SOC and TN were significantly (P<0.05)，but had no effect on TP (P>0.05),the distance only had significant effect on SOC，while the effects of the 3 were significantly affected (P<0.05).Nitraria sand soil pH and total salt make contribut to C/N，C/P，N/P，TN and SOC，while TP had an negative effect on C/N.
