英文摘要：

In this paper,we discuss the existence of positive solutions for a class of nonlinear boundary value problem of fractional differential equations with integral boundary conditions. By using Green＇s function and Guo-Krasnoselskii fixed point theorem, the new existence of boundary value problems were obtained. Our results enrich and improve some existing research results.
