摘　　要：地表覆盖是地理国情普查的主要内容之一,针对其空间分布格局问题,提出了基于景观要素特征-景观空间格局-景观空间构型的景观健康分析与评价模型。结合GIS技术和Fragstats软件,基于2014年地理国情普查试点数据,利用层次分析法和综合指数法,对地表覆盖的景观格局健康状况进行分析与评价。结果表明,试验区的景观结构与格局健康水平较低,其原因主要是水域景观要素特征与景观空间格局的健康水平、草地景观要素特征与景观空间构型的健康水平都较低。An analysis and evaluation model of the landscape health based on the landscape elements features-landscape spatial pattern-landscape spatial configuration was proposed for land coverts spatial distribution pattern problem, which is one of the main contents of geographic conditions census. Combined with GIS technology and Fragstats software, based on 2014 geographic conditions census data of the experimental area,using AHP and comprehensive index method,the landscape pattern health status of land cover was analyzed and evaluated. The results showed that the health level of landscape structure and pattern of exerimental area is low, mainly due to the poor health level of waters＇ landscape elements characteristics, the lower health level of the grass＇s landscape elements characteristics and landscape configurations health.
