从西部高校图书馆资源建设现状分析指出了资源共建共享的必要性。而当今流行的云计算技术能够很好地支持共建共享平台建设发展。因此通过对云计算技术的概念、设计理念、服务模式等方面进行了详细的说明,并在此基础上提出了针对西部高校发展现状的云计算服务模式,云环境下资源共建共享五个方面的策略。为今后西部高校图书馆资源共建共享研究给出了理论依据和参考价值。 This paper points out the necessity of co - construction and sharing of resources by analyzing the present situation of resource construction in western university libraries. And today’s popular cloud computing technology can well support the construction and development of shared platform. Therefore, the concept of cloud computing, design philosophy, service model and other aspects are described in detail. Based on this, five aspects of cloud computing service model for the development of western universities and the sharing and sharing of resources in cloud environment are proposed Strategy. It provides the theoretical basis and reference value for the future research on the resources co-construction and sharing of western university library.
