    摘要:

    [目的]生境质量是反映区域生态系统服务功能及水平的重要指标,明晰郑州市土地利用格局和生境质量时空演变特征并预测未来发展趋势,为区域生态保护实践和可持续发展提供理论参考。[方法]基于PLUS模型和InVEST模型,同时结合ArcGIS空间分析及地理信息图谱法,分析2000—2020年郑州市土地利用变化情况并模拟2030年基准情景和生态保护情景下的空间分布格局,探究郑州市生境质量时空演变规律和像元尺度下的迁移状态。[结果]①2000—2020年,耕地和建设用地为郑州市主要景观类型,20年间,建设用地面积激增,涨幅15.76%且主要来源于耕地;②PLUS模型对郑州市土地利用模拟具有适用性,相较于基准情景,2030年生态保护情景下建设用地扩张受限,生态用地总量上升,该情景可为研究区推进生态建设提供参考;③2000—2020年生境质量不断退化,空间分布差异显著,高生境质量区始终位于巩义市和登封市,低和较低等级的图谱单元相互转移最频繁;④2030年延续“西高东低”格局,生态保护情景下生境质量呈“低值减少、高值增多”的特征,向较高和高等级转移率升至14.44%,与基准情景相比表现出稳中向好的发展趋势。[结论]郑州市生境质量时空分布与土地利用变化密切相关,未来应注重国土空间结构的合理布局,增强土地利用效率,提升生态系统质量和稳定性。

    Abstract:

    [Objective] Habitat quality is an important index to reflect the function and level of regional ecosystem services. To clarify the spatial and temporal evolution characteristics of land use pattern and habitat quality in Zhengzhou City and predict the future development trends, in order to provide theoretical references for regional ecological conservation practice and sustainable development. [Methods] Based on the PLUS model and InVEST model, combined with the spatial analysis of ArcGIS and the geo-spectrum information method, we analyzed the land use changes in Zhengzhou City from 2000 to 2020, and simulated the spatial distribution pattern under the baseline scenario and the ecological protection scenario in 2030. Then explored the spatial and temporal evolution laws of habitat quality and the migration status of the pixel scale. [Results] ①From 2000 to 2020, cultivated land and construction land were the main landscape types in Zhengzhou City. Over the past 20 years, the area of construction land increased sharply by 15.76% and mainly derived from cultivated land. ②The PLUS model is applicable in Zhengzhou City. Compared with the baseline scenario, the expansion of construction land was limited and the total amount of ecological land rised under the ecological protection scenario, which could provide a reference for promoting ecological construction in the study area. ③The habitat quality degraded continuously with significant spatial distribution differences from 2000 to 2020. High habitat quality areas consistently located in Gongyi and Dengfeng cities, low and medium-low map units transferred to each other most frequently. ④In 2030, the pattern of "high in the west and low in the east" continues. Under the ecological protection scenario, habitat quality is characterized by the "decrease in low values and increase in high values", and the transfer rate to the high and medium-high grades rises to 14.44%, showing a stable and positive development trend compared with the baseline scenario. [Conclusion] The spatial and temporal distribution of habitat quality in Zhengzhou City is closely related to land use changes. The study area should focus on the rational layout of national spatial structure, enhance the efficiency of land use, and improve the quality and stability of ecosystem in the future.
