摘要
高质量生境对于维护生态系统平衡、促进人类社会和经济发展具有重要作用。本文通过研究四川盆地生境质量,更好地揭示人类活动对盆地生态系统的影响,为研究区生态系统的修复和发展提供一定的科学依据。结果表明:四川盆地2000—2020年的生境质量状况整体水平不高,但呈微弱上升趋势;生境质量空间分布上异质性表现明显,呈现研究区边缘生境质量状况较好、中间盆地底部生境质量整体较差的空间分布特征。生境质量与土地利用程度在空间上呈负相关,且相关程度缓慢减弱。研究结果确定了四川盆地生境质量相对较差的区域,对维护四川盆地生物多样性以及日后的发展规划具有一定的参考价值。
High-quality habitats play an important role in maintaining ecosystem balance and promoting human social and economic development.By studying the habitat quality of the Sichuan basin,this paper can better reveal the impact of human activities on the basin ecosystem,and provide a certain scientific basis for the restoration and development of the ecosystem in the study area.The results showed that the overall level of habitat quality in the Sichuan basin from 2000 to 2020 was not high but showed a slight upward trend.The spatial distribution of habitat quality showed obvious heterogeneity,showing the spatial distribution characteristics of good habitat quality at the edge of the study area and poor overall habitat quality at the bottom of the middle basin.Habitat quality and land use degree were negatively correlated in space,and the correlation degree gradually weakened.The research results identify areas with relatively poor habitat quality in the Sichuan basin,which have certain reference value for maintaining biodiversity and future development planning in the Sichuan basin.
