摘　　要：城市化背景下的土地利用变化加剧对生态环境产生恶劣影响,评估生境质量对区域生物多样性保护和生态安全的可持续发展具有重要意义。利用土地利用动态度分析土地利用格局时空演变过程,基于Markov-PLUS模型耦合InVEST模型预测评估2000—2030年赣州市生境质量的时空演变,根据不同等级生境质量斑块分析其景观格局特征。结果表明,2000—2020年,人造地表和湿地面积变化最为明显,分别达到土地利用动态度最大值与最小值。2000—2030年,赣州市生境质量平均指数达到0.814。主要类型以较低生境质量和高生境质量为主,低生境质量呈现剧增的态势,主要集中在赣州市都市区。生境质量斑块优势度降低、复杂度提升、连通性差以及受到人类活动干扰大。因此,土地利用变化对赣州市生境质量及其景观特征有着决定性的作用,合理规划用地类型,实现“生态-经济-社会”最优权衡。The intensification of land use change under the background of urbanization is negatively impacted by the ecological environment.Therefore,the assessment of habitat quality is deemed of great significance for the preservation of regional biodiversity and the promotion of ecological security in a sustainable manner.The spatio-temporal evolution of land use patterns was analyzed using land use dynamic attitude.The evolution of habitat quality in Ganzhou city from 2000 to 2030 was predicted based on the Markov-PLUS model and InVEST model,and the characteristics of the landscape pattern were analyzed with respect to different habitat quality patches.The results indicated that from 2000 to 2020,the changes in artificial land surfaces and wetland areas were most pronounced,with the maximum and minimum of land use dynamic attitude being reached,respectively.From 2000 to 2030,an average habitat quality index of 0.814 was achieved in Ganzhou city.The main types were low habitat quality and high habitat quality,with the low habitat quality displaying a dramatic trend,primarily concentrated in the Ganzhou metropolitan area.The dominance of habitat quality patches was reduced,complexity was increased,connectivity was poor,and there was significant interference by human activity.Therefore,a decisive role is played by land use change in the habitat quality and landscape characteristics of Ganzhou city.The optimal balance of“ecological-economic-social”can be achieved through the rational planning of land use types.
