The invention discloses a virtual network resource allocation method based on active detection under a network slice. The method comprises the following steps of: constructing a virtual network resource allocation model comprising a bottom layer network and a virtual network, detecting the bottom layer network by adopting an active detection method to establish an alternative detection set, screening the alternative detection set based on a vector expansion basis theory to obtain an optimal alternative detection set; determining an alternative bottom-layer node set according to the optimal alternative detection set, calculating the adjacent distance of each alternative bottom-layer node, and allocating CPU resources to the virtual nodes according to the adjacent distances; and each detection in the optimal alternative detection set detecting the underlying network by using an active detection method to obtain bandwidth resources of each underlying link through which the detection passes, and allocating the ba
