摘要
闽新轴带是联系陆海丝绸之路核心区的便捷大通道,在"一带一路"倡议下区域合作格局逐渐形成.此背景下以1990年、2000年、2010年和2015年4期闽新轴带土地利用数据为基础,利用价值量评估法、地理探测器等方法,对研究区的生态系统服务价值及其分布影响因素进行了定量评估.从各项生态系统价值,单项生态功能价值、县域生态系统价值、全局空间分布价值等多尺度、多角度分析了闽新轴带生态系统服务价值时空动态演变情况,并对其空间分布的影响因子进行定量测算,揭示了闽新轴带生态系统服务价值演变规律和生态安全格局基本特征.构建了生态安全格局,并提出研究区生态安全格局的优化策略.研究表明:4期的闽新轴带的生态系统服务价值分别为13 015.59亿元、13 159.91亿元、13 184.03亿元和13 174.60亿元,呈现先增后减的变化趋势;在各省区中新疆地区的生态价值最高,平均单位面积生态价值为5 728.83元·hm^(-2),生态系统服务价值空间分布集聚特征显著且变化维持较高的稳定性;地理探测器的探测结果表明人口密度因子为影响研究区生态价值空间分布的主要因素;整体生态安全格局维持在相对有效的保护之下,但仍需增强各生态系统之间的连通性和稳定性,可建成"东南生态带动、中部生态支撑、西北生态崛起"的生态安全格局.
Min-Xin Axis Belt refers to a zone which connects areas from Xinjiang to Fujian in China. As a convenient and large channel to link the Silk Road Economic Belt and the 21 st-Century Maritime Silk Road, the Min-Xin Axis Belt has gradually formed in the regional cooperation pattern under the "Belt and Road" strategy. Based on the Min-Xin Axis Belt land use data of 1990, 2000, 2010 and 2015, the ecosystem service value and its distribution influencing factors were quantitatively evaluated by using the value evaluation method and geographic detector, and the temporal and spatial dynamic evolution of the ecosystem service value of the research area was analyzed from multi-scale and multi-angle such as various ecosystem values, individual ecological function values, county ecosystem values, and global spatial distribution value. Meanwhile, the influence factors of the spatial distribution of the Min-Xin Axis Belt were quantitatively calculated, the evolution law of the ecosystem service value and the basic characteristics of ecological security pattern were revealed. The ecological security pattern in the study area was constructed and the optimization strategy was put forward.. The research shows:(1) The ecosystem service values of the Min-Xin Axis Belts in 1990, 2000, 2010 and 2015 were 1.302×10^(12) Yuan, 1.316×10^(12) Yuan, 1.318×10^(12) Yuan and 1.317×10^(12) Yuan respectively, showing a change trend of increasing first and then decreasing.(2) Among the provinces and autonomous regions, Xinjiang has the highest ecological value, with an average ecological value per unit area of 5 728.83 Yuan·hm^(-2). In addition, the spatial distribution agglomeration characteristics are significant and maintained high stability.(3) The detection results of geo-detectors show that population density is the main factor affecting the spatial distribution of ecological value in the study areas.(4) Although the overall ecological security pattern was maintained under relatively effective protection, the connectivity and stability
