都市圈“三生空间”协同变化及其对生态系统服务的影响

Synergistic Changes of Production-Living-Ecology Spaces and Their Influences on Ecosystem Services in the Metropolitan Area

[目的]“三生空间”时空变化及其对生态系统服务影响的研究可以揭示人地关系及其变化规律,为区域国土空间管控提供理论依据。[方法]本研究以典型都市圈--济南都市圈为例,分析了2000-2018年“三生空间”变化趋势,刻画了三生空间协同变化类型与特征,并评价了济南都市圈生态系统服务价值及其变化,最终揭示了“三生空间”变化对区域生态系统服务的影响。[结果]总体变化特征上,生活生产空间是唯一面积增长的“三生空间”类型,且其面积相对变化速度在各类型中最快,对应动态度为2.4%;400 245.31 hm^(2)的生产生态空间转入生活生产空间,是生活生产空间扩张的主要来源;“三生空间”协同变化可划分为5种特征明显、空间上互不重叠的类型,包括生态-生活协同变化型,生产-生活协同变化型,生态变化主导型,三生稳定型,生活变化主导型;在各协同变化类型中,生活变化主导型区县的生态系统服务价值下降最为剧烈[-3 015.89元/(hm^(2)·a)];在各转换类型中,生产生态空间向生活生产空间的转换对区域生态系统服务价值的不利影响最明显。[结论]研究提出了“三生空间”协同变化类型的划分方法,揭示了济南都市圈“三生空间”变化特征及其对生态系统服务的影响,可为“三生空间”理论研究提供补充,为国土空间规划中土地用途管制与国土空间分区管理等提供参考。

[Objective]Research of spatiotemporal changes of the production-living-ecology spaces(PLES)can reveal the human-land relationship and its changing rules,and can further provide theoretical evidence for regional territorial space control.[Methods]Using a typical metropolitan area(the Jinan Metropolitan Area)as the case study area,we investigated the spatiotemporal changes of the PLES from 2000 to 2018 and identified the types and characteristics of the synergetic PLES changes,and then we further evaluated ecosystem service values and their changes of the Jinan Metropolitan Area.Finally,we revealed the influences of the PLES changes on regional ecosystem services.[Results]In terms of the overall PLES change characteristics,the living-production space was the only type with an increase in the area.Among different PLES types,the living-production space had the rapidest changing speed reflected by the dynamic degree of 2.4%.The production-ecology space with the area of 400245.31 hm^(2)transferred into the living-production space,acting as the main source of the living-production space expansion.The synergistic PLES changes were further divided into five types with significant characteristics and no spatial overlaps,including the ecological-living synergistic change type,the production-living synergistic change type,the ecological change dominance type,production-living-ecological stability type,and living change dominance type.Among different synergistic PLES change types,the districts/counties with the living change dominance type exhibited the most significant decrease in ecosystem service values〔-3015.89 yuan/(hm^(2)·a)〕.Among different transfer types of the PLES,the transfer from the production-ecology space to the living-production space had the most negative impacts on ecosystem service values.In this study,we proposed the classification methodology of PLES synergetic changes.[Conclusion]Our study revealed the characteristics of PLES changes and the influences of PLES changes on ecosystem service values in the Jinan Metropolitan Area,which can supplement theoretical research on the PLES.The results of this study can support land use control and zoning management in territorial spaces planning.
