The invention relates to a multi-energy complementary distributed energy and resource comprehensive energy supply system and an energy supply method. An existing distributed energy and resource utilization system is too independent, lacks complementarity and interactivity, and has the problems that the system efficiency is low, the resource and energy utilization rate is low and the like. According to the system and the method, various distributed energy sources and various resources can be complemented and utilized, the energy utilization efficiency is improved, meanwhile, the resource utilization can also be optimized, so that interconnection and interworking and efficient cyclic utilization of multi-energy complementary distributed energy sources and resources are achieved; the defectsof the existing energy system and resource utilization in technologies and applications are overcome, 100% recycling and reusing of the energy sources, garbage, plants and sewage are realized, and resource recycling is improved; and therefore, the energy crisis is solved, the environmental pollution is reduced, the ecological environment is protected, the comprehensive utilization work of the resources is promoted, the comprehensive utilization rate is improved, and the integrated target of the distributed energy resources, low-temperature geothermal resources and garbage recycling is realized.
