“三生空间”视角下滇中城市群景观生态风险评价及驱动因素研究

Landscape Ecological Risk Assessment and Driving Factors of Urban Agglomeration in Central Yunnan from the Perspective of Production-Living-Ecological Space

  • 摘要: 基于滇中城市群2000年、2005年、2010年、2015年、2020年5期土地利用数据,通过土地利用动态度、转移矩阵、景观生态风险指数、空间自相关分析等方法,从“三生空间”视角对滇中城市群景观生态风险进行评估,并探究其驱动因素。结果表明:生态空间是研究区的主要“三生空间”类型(约77%),生产空间次之,生活空间较少(不足2%);研究期内城镇生活空间和工业生产空间大幅增加,而林地、草地生态空间和农业生产空间不断缩减。2000—2020年,研究区综合生态风险水平不断上升,但仍处于较低水平范围内,景观生态风险在空间上具有较强的正相关关系,热点区主要集中在城市群中东部地区。研究区景观生态风险的空间分异受自然因素和人为因素的共同影响,其中人为因素是导致景观生态风险升高的主要原因。因子之间交互作用效果明显高于因子单独作用,研究期内,交互作用效果先增强后减弱。研究结果可为管控区域生态风险与合理配置土地资源提供参考。

     

    Abstract: Based on the land use data of central Yunnan urban agglomeration for 5 periods of 2000, 2005, 2010, 2015, 2020, we assessed the landscape ecological risk of central Yunnan urban agglomeration from the "Production-Living-Ecological Space" perspective and explored its driving factors by means of land use dynamic attitude, transfer matrix, landscape ecological risk index, and spatial autocorrelation analysis. The results show that ecological space is the main type of "Production-Living-Ecological Space" in the study area(about 77%), followed by production space and less living space(less than 2%). During the study period, urban living space and industrial production space rose dramatically, while forest land, grassland ecological space and agricultural production space decreased consistently. From 2000 to 2020, the level of comprehensive ecological risk in the study area rises but remains modest, and landscape ecological risk has a strong positive spatial association, with hotspot areas mostly centered in the central-eastern part of the urban agglomeration. The spatial differentiation of landscape ecological risk in the research area is influenced by both natural and human factors, with human factors being the primary cause of landscape ecological risk rise. The interaction effect between factors is obviously higher than that of individual factors, and the interaction effect first increases and then decreases during the study period. The results of the study can provide a reference for the control of regional ecological risks and rational allocation of land resources.
