摘要: 以2000—2020年山西省太原市土地利用数据为基础,利用Fragstats软件计算景观格局指数,分析景观格局变化;运用“压力-状态-响应”(PSR)模型和熵权法对太原市生态系统健康状况进行评价。结果表明,耕地、草地和林地为太原市的优势景观类型,面积占比大;建设用地面积逐年扩张,且涨幅较大;水域和其他用地类型面积占比小,连通性差;整体景观呈均质多样化趋势发展,景观破碎化程度加深;太原市整体生态系统健康状况表现出南北优、中部劣的分布格局;2000—2015年,太原市生态系统健康指数整体呈下降趋势,2015年降至最低值,2015—2020年生态系统健康指数有所上升;城市化、人口密度和人类干扰度与太原市生态系统健康极显著相关(P<0.01)。

Abstract: Based on the land use data of Taiyuan City, Shanxi Province from 2000 to 2020, the Fragstats software was used to calculate the landscape pattern index and analyze the change of landscape pattern. The “pressure-state-response” (PSR) model and entropy weight method were used to evaluate the ecosystem health status of Taiyuan City. The results showed that cultivated land, grassland and forest land were the dominant landscape types in Taiyuan City, and their areas accounted for a large proportion. The construction land area expanded year by year, and the increase was large. The area of water and other land types was small, and the connectivity was poor. The overall landscape showed a trend of homogeneity and diversification, and the fragmentation of the landscape was deepened. The overall ecosystem health of Taiyuan City showed the distribution pattern of good in the north and south region, and bad in the central region. The comprehensive index of ecosystem health in Taiyuan City showed a downward trend from 2000 to 2015, and reached the lowest value in 2015. The comprehensive index of ecosystem health increased from 2015 to 2020. The indicators of urbanization, population density and human disturbance were significantly correlated with ecosystem health in Taiyuan City(P<0.01).

Key words: landscape pattern, PSR model, ecosystem health, land use, Taiyuan City
