研究雄安新区生态系统碳储量和生境质量,对生态修复和环境可持续发展有重要意义.基于InVEST模型,首先评价雄安新区碳储量和生境质量两项服务功能,然后将评价结果采用综合指数法进行叠加,进一步评价雄安新区生态系统服务综合重要性.研究结果表明:2005-2020 年,雄安新区碳储量和生境质量分布格局基本稳定;不同土地利用类型固碳能力的大小与碳密度值呈现较高的一致性,碳储量最低的是建设用地,最高的是滩地,耕地的碳储量处于中间水平,不同土地利用类型生境质量在整个研究期较为稳定,生境质量高值区大部分集中成片分布于白洋淀区域,部分零星分布于研究区其他地区,水域的生境质量一直维持在较高水平;雄安新区生态系统服务功能综合重要性处于中等水平,白洋淀流域综合重要性水平高于其他区域.
Analysis of Spatiotemporal Changes in Carbon Storage and Habitat Quality in Xiong'an New Area Based on InVEST Model
Studying the carbon storage and habitat quality of the ecosystem in Xiong'an New Area is of great significance for ecological restoration and sustainable environmental development.Based on the In-VEST model,the two service functions of carbon storage and habitat quality in Xiong'an New Area are first evaluated,and then the evaluation results are overlaid using the comprehensive index method to fur-ther evaluate the comprehensive importance of ecosystem services in Xiong'an New Area.The research re-sults indicate that from 2005 to 2020,the distribution pattern of carbon storage and habitat quality in Xiong'an New Area was basically stable.The carbon sequestration capacity and carbon density values of different land use types show high consistency.The lowest carbon storage is in construction land,the highest is in beach land,and the carbon storage of cultivated land is in the middle level.The habitat quali-ty of different land use types is relatively stable throughout the entire research period,and most of the high value areas of habitat quality are concentrated in the Baiyangdian area,while some are scattered in other areas of the research area,The habitat quality of the water area has always been maintained at a high level,The comprehensive importance of the ecosystem service function in Xiong'an New Area is at a moderate level,while the comprehensive importance level of the Baiyangdian Basin is higher than that of other re-gions.
