Land Suitability Evaluation of Earthquake Resistance and Hazardous Prevention Planning Based on Niche Construction

The research on the relation between niche construction and its evolution is a new field of study of the niche theory.Taking hazardous resistant site of land use as the research object,this study makes a systematic analysis of the development of the concept of niche,the mechanism of the niche construction and the special pattern of the coordinated evolution of hazardous resistant site of land use and the change of their environments.This paper proposes the evolutionary inertia measured by the fitness of the niche of hazardous resistant site of land use and the evolutionary momentum measured by the deviation between the real niche and the optimal niche.This paper also sets up the appropriate mathematical model by making a case study of 5 sites in one city.The study results can be used as the theoretical basis for hazardous resistant suitability of land use to evaluate and choose.
