The invention discloses a non-treatment-oriented method for constructing a zebrafish model used for sifting drugs for treating Parkinson's diseases. The method is characterized in that LRRK2 mutationzebrafish is put in 1-5 mM of a hydrogen peroxide solution, and it takes only 3-6 days to construct the zebrafish model. By means of the method, the model for the Parkinson's diseases is constructed in the zebrafish by combining multiple factors such as genes, environments and ageing, and the Parkinson's diseases are simulated in animals with high fidelity; by using the animal model as a medium, relevant micromolecule compounds and genetic engineering recombinant proteins are sifted, and the drugs which are made from the micromolecule compounds and the genetic engineering recombinant proteinsand can obviously avoid deficiency of dopaminergic neurons and lowering of the behavior activeness are obtained. The sifting method is simple, the cost is low, and the stability and reliability are high.
