摘　　要：基于对现有确定场地平土标高研究的基础,分析场地平土标高确定的过程与生态环境之间的相互影响关系;从保护生态环境的角度出发,兼顾土方平衡与土方量最小的要求,建立一种确定平整场地后平土范围内对原有自然地形的微生物损毁量的计算模型.利用遗传算法进行求解,得到微生物损毁量最小情况下的最优场地平土标高.结合实例,对某工业企业的场地平整方案进行微生物损毁的量化分析,从生态环境保护的角度给出确定场地平土标高的最优方案.Mutual influence of the process of site grading elevation determining and the ecological environment on each other was analyzed based on available research on the determination of site grading elevation. In view of ecological environment protection and paying attention to the balanced and minimum earthwork, a calculation model of microbial damage quantity on original natural topography due to the determination of site grading was established. The model was solved by using genetic algorithm and the optimal site grading elevation was obtained under the conditions that the microbial damage is minimal. Finally, an actual site grading scheme of an enterprise was taken to conduct quantitative analysis of microbial damage and the optimal solution of the site grading elevation was given from the point of view of protection of ecological environment.
