摘　　要：针对当前云计算内部资源管理模式的缺陷,导致资源的利用率低下。为提高资源的利用率,研究提出一种适合云环境的资源需求态势感知方法,通过采用AHP(层次分析法)对云环境下当前时刻资源的使用情况进行态势评估,同时使用改进的BP算法对下一时刻资源的需求情况进行态势预测,为资源合理分配提供依据,提高资源利用率,实现资源的高效利用。In view of the defects of the current cloud computing resource management, which resulting in low utilization of resources. In order to improve the utilization of resources and achieve its efficient use, this paper pro-poses a new method of resource requirement for cloud computing environment which is based on situation aware-ness. By using AHP （Analytic Hierarchy Process） to assess the current situation of the use of resources. A t the same time, the improved BP （Back Propagation） algorithm is used toforecast the resource requirement of the next time which can provide the basis fo r rational allocation.
