This paper analyzes the obstacles that lie in the share of high-quality digital teaching resources, and puts forward the corresponding countermeasures, which is a model of sharing resources based on cloud computing. This paper expounds the characteristics of cloud computing and the advantage of constructing resource with it, and describes its implementation mechanism. Finally the author puts forward several problems which need to be aware of in the construction of the shared resources. Through the integration of high quality teaching resources, the mutual construction, sharing and use of the digital teaching resources can be realized.%分析了当前优质数字教学资源共享存在的阻碍,并提出了相应的对策,即基于云计算的资源共享模式,阐述了云计算的特点和运用其建设资源库的优势,并描述了其实现机制。最后提出了共享资源库建设需要注意的几个问题。通过整合优质教学资源,实现数字教学资源的共建、共享和共用。
