The invention provides a nucleic acid detection microsphere and a preparation method thereof, a kit and a high-throughput nucleic acid detection method. The nucleic acid detection microsphere is composed of nuclear bodies with fluorescence coding information and a coating layer of primers or probes. A variety of the nucleic acid detection microspheres are randomly distributed into micro-droplets generated by a nucleic acid reaction solution of a to-be-detected sample. When a temperature rises to 60 DEG C or above, the coating layers melt, and the primers and the probes are released into the nucleic acid reaction solution of the to-be-detected sample, so a complete nucleic acid amplification reaction system is formed; and the fluorescence coding nuclear bodies are left in a nucleic acid amplification solution and serve as fluorescence labels for marking the micro-droplets. By detecting the nuclear bodies with fluorescence coding information in each micro-droplet, the micro-droplet withonly one nuclear body is screened out as an effective droplet and subjected to subsequent analysis to obtain primer and probe types in the effective micro-droplet; and then a report fluorescence signal after a nucleic acid amplification reaction is read so as to determine whether corresponding to-be-detected target nucleic acid molecules exist in the effective micro-droplet or not.
