摘要:
生态安全是地区社会经济可持续发展的基本前提之一,而生态环境脆弱性会威胁地区的生态安全,进行生态环境脆弱性评价具有重要意义。以闽三角城市群为例,分别选取2000年和2015年的高程、坡度、岩性、土壤类型、NDVI、年均降水量、年均温、人口密度、人均GDP、路网密度、景观多样性、土地利用程度和工业固体废弃物排放量等13个指标,基于空间主成分分析法,并结合全局Moran'I和LISA聚类图,从整体特征、空间差异、空间集聚、地类脆弱性分异以及驱动力5个方面,探讨闽三角城市群的生态环境脆弱性及其驱动力。结果表明:2000-2015年间,闽三角城市群的生态环境脆弱性整体处于中度脆弱,但呈现出由中度脆弱向重度脆弱过渡的趋势;2000-2015年间,生态环境脆弱性呈现出由东南沿海向西北内陆逐渐增强的整体趋势,并存在明显的地带性特征,东南沿海增长不明显,部分地区有所下降,而西北内陆增长明显;生态环境脆弱性存在显著的空间自相关性,且为显著正相关,在西北部山区地带为显著的高高聚集,在东南沿海平原地带为显著的低低聚集,16年间集聚性特征在空间上有所迁移和扩张;2000-2015年间,生态环境脆弱性在各地类存在着一定的异质性,其生态环境脆弱性指数大小顺序始终为:林地 > 未利用地 > 草地 > 耕地 > 水域 > 建设用地,整体由中度脆弱向重度脆弱过渡;2000-2015年间,生态环境脆弱性的驱动力有所变化,但人口密度、景观多样性、岩性和土壤类型一直是闽三角城市群生态环境脆弱性主要的驱动力。
Abstract:
Ecological security is one of the fundamental guarantees for regional social and economic sustainable development; however, ecological environmental vulnerability threatens regional ecological security, which is essential for evaluating ecological environmental vulnerability in urban agglomeration in the Fujian Delta region. We selected 13 factors, including elevation, slope, lithology, soil type, normalized difference vegetation index, annual mean precipitation, annual mean temperature, population density, per capita GDP, road density, landscape diversity index, degree of land use, and industrial solid waste emissions in 2000 and 2015, based on the spatial principal component analysis method, combined with global Moran 'I and LISA clusters based on five quantitative characteristics, spatial patterns, spatial clustering, vulnerability differentiation of land use, and driving force to analyze the ecological environmental vulnerability and its driving force in urban agglomeration in the Fujian Delta region. The results showed medium ecological environmental vulnerability in urban agglomerations in the Fujian Delta region, but showing an increasing trend from medium to strong vulnerability from 2000 to 2015. From 2000 to 2015, ecological environmental vulnerability showed an overall gradual increasing trend from the southeastern coast to the northwestern inland, with obvious zonal characteristics. The increase in the ecological environmental vulnerability was not obvious in the southeastern coastal area, and even declined in some areas, but increased significantly in the northwestern inland. Ecological environmental vulnerability had a significant spatial autocorrelation, and significant positive correlation, with a significant high-high clustering in the northwestern inland and a significant low-low clustering in the southeastern coastal area. The clustering characteristics showed some spatial migration and expansion over 16 years; from 2000 to 2015, there was a relative heterogeneity under different land use types, and the ecological environmental vulnerability index was always in the following order: forest land > unused land > grassland > farmland > wetland > construction land, with a transition from medium to strong vulnerability. The driving force of ecological environmental vulnerability changed from 2000 to 2015, but population density, landscape diversity, lithology, and soil type were the main driving forces in urban agglomeration in the Fujian Delta region.
