针对森林火灾后生态变化的复杂多样性和模糊性，采用模糊数学中“多层次模糊综合评判”的方法，对云南松林火烧迹地生态变化进行评价，以期探索森林火灾后生态监测评价的新途径，为森林生态系统的恢复和重建提供科学依据和决策支持。
In view of the complex diversity and fuzziness of ecological changes after forest fires, the method of “multi-level fuzzy comprehensive evaluation” in fuzzy mathematics is used to evaluate the ecological changes of burned pine forests in Yunnan in order to explore new ways of ecological monitoring and evaluation after forest fires, Provide scientific basis and decision-making support for the restoration and reconstruction of forest ecosystem.
