基于生态位构建的抗震防灾规划土地适宜性评价

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

    • 摘要: 针对城镇土地利用抗震防灾适宜性评价的特点,利用生态位构建理论以抗震防灾场地为对象,系统地分析了生态位内涵的发展、生态位构建的机理,以及土地利用抗震防灾场地与环境变化间协同进化的特殊规律,提出用土地利用抗震防灾场地生态位的适合程度测定其进化惯量,用现实生态位对其最佳生态位的偏离程度测定其进化动量,建立相应的数学模型,进行实例计算与分析,结果可以为土地利用防灾适宜性评价与选择提供理论依据.

       

      Abstract: 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.
