摘要

开展长江三角洲(长三角)区域生态系统变化与城市化发展权衡协同关系研究,对于厘清城市化发展与生态环境变化规律,并提出差异化的生态环境保护和城市发展建议具有重要意义.基于MOD17A3 NPP和夜间灯光数据集(PANDA)数据,利用相关系数法和变化趋势情景组合综合分析长三角区域生态系统净初级生产力(NPP)和灯光强度的时空变化趋势及两者之间的权衡协同关系.结果表明,长三角区域生态质量整体向好,区域NPP从2000年的447.19 g·m-2·a-1增加到2020年的529.92 g·m-2·a-1;长三角区域城市化发展持续上升,灯光强度由2000年的436.79上升到2020年的1 012.06,呈增加趋势的区域面积占总面积的91.79％,空间分布上呈现各地市中心城区向四周扩散降低,随着距城市中心距离减少而逐渐增加的集聚效应.经济社会与生态环境高质量协同发展成为长三角区域的主要趋势,灯光强度和NPP同步明显增加的区域面积占总面积的33.93％,两者呈协同关系的区域面积占其面积的比例为61.44％,主要分布在长江三角洲平原的城市周边;呈权衡关系的区域较少,其面积占总面积的4.67％,主要表现为灯光强度显著增加而NPP显著降低,主要位于上海、苏锡常都市圈等城市化发展迅速的地区.

Abstract

Studying the trade-off and synergistic relationship between ecosystem change and urbanization development in the Yangtze River Delta Region is highly important for clarifying the relationship between urbanization development and ec-ological environment change and for proposing differentiated ecological environment protection and urban development sug-gestions.Based on the MOD17A3 NPP and the Nightlight Dataset(PANDA),the temporal and spatial trends in the net primary productivity and light intensity of ecosystems in the Yangtze River Delta and their trade-offs and synergies were comprehensively analyzed by using the correlation coefficient method and trend scenario combination.The results show that the ecological quality in the Yangtze River Delta improved,and the NPP increased from 447.19 g·m-2·a-1 in 2000 to 529.92 g·m-2·a-1 in 2020.Urbanization in the Yangtze River Delta Region has continued to increase,with light inten-sity increasing from 436.79 in 2000 to 1 012.06 in 2020,and the area with an increasing trend accounted for 91.79％of the total area.The spatial distribution shows that the agglomeration effect of the downtown area spreading to the periphery decreases and gradually increases with decreasing distance from the city center.High-quality coordinated development of the economy,society and ecological environment has become the main development trend in the Yangtze River Delta Re-gion,and areas with significant increases in both light intensity and NPP account for 33.93％of the total area.Among them,61.44％of the regions exhibited synergistic relationships,which were mainly distributed in the areas around the cit-ies in the Yangtze River Delta Plain.There are fewer areas with a trade-off relationship,and these areas account for 4.67％of the total area,with the manifestations of significant increases in light intensity and significant decreases in NPP,and they are mainly located in areas of rapid urbanization,such as Shanghai and Suzhou-Wuxi-Changzhou metropolitan area.
