A composite toughened and high-temperature-resistant polylactic acid modified material and a preparation method therefor. The polylactic acid modified material is prepared from the following raw materials in parts by mass: 30-60 parts of polylactic acid, 20-50 parts of polybutylene succinate, 5-12 parts of inorganic filler, 0.5-1.2 parts of chain extender, 1-10 parts of plasticizer, 0.5-10 parts of toughening agent, 0.2-0.6 parts of compatiblizing agent, and 0.1-0.6 parts of temperature-resistant agent. The composite toughened and high-temperature-resistant polylactic acid modified material still keeps the degradable characteristic of the polylactic acid; and the preparation method is simple and easy to implement, and can change the performance of the polylactic acid by changing the content of the toughening agent and the degree of crosslinking.
