摘要:
【目的】通过对上海黄浦江河岸带景观格局空间特征进行分析,找出该河岸带生态修复的重点区域与景观类型,科学规划河岸带的生态恢复重建,为黄浦江周边的土地利用格局优化与景观生态修复建设提供决策支持。【方法】基于地理信息系统(GIS)平台,利用高分辨率航拍图像数据源,构建河岸带土地利用与景观格局数据库,从横向、纵向两个维度,利用景观指数方法,在景观类型和景观格局两个水平,选取不同的景观指数对黄浦江河岸带景观格局空间特征进行定量分析。【结果】①在横向维度上,黄浦江河岸带市区段城市化程度最高,景观多样性最低,绿地和林地所占比例不足且碎片化; 近郊段属于过渡河段,以工业用地为主,景观多样性最高,破碎化程度最严重; 远郊段人为干扰程度最低,土地利用强度最弱,农田生态林网体系建设有待加强。②在纵向维度上,根据距河道边缘的距离(L),0≤L<100 m的河岸带受到重点生态保护,但距河道距离由近至远,人为干扰强度逐渐增强,河岸带景观多样性与破碎化程度呈现先增后减的趋势,在300≤L<400 m的河岸带景观破碎化程度最显著。【结论】城市建设活动的干扰,造成黄浦江河岸带景观格局趋于破碎,存在水陆交错边缘的负效应。在景观类型水平上,工业用地、生产防护林地和旱地是河岸带生态修复应重点关注的景观类型,而在景观格局水平上,近郊段河岸带(横向维度)和300≤L<400 m的河岸带及邻近区域(纵向维度)是生态修复重点区域。
Abstract:
【Objective】 The objective of this study was to analyze the spatial characteristics of the riparian landscape of Huangpu River in order to find priority areas and landscape typologies for riparian ecological restoration. The outcome of this study can provide decision support for optimization of land use allocation, as well as landscape and ecological restoration around the area of Huangpu River.【Method】Based on high-resolution aerial images, a database of land use and landscape pattern within the riparian zone was constructed on the GIS platform. The spatial characteristics of landscape pattern in the riparian zone were analyzed by applying the quantitative landscape index method to both landscape class and pattern levels in longitudinal or cross-sectional directions.【Result】① In the cross-sectional dimension, urban areas exhibited the highest degree of urbanization and the lowest landscape diversity, as confirmed by spare and fragmented green lands and forests. We found the highest landscape diversity and degree of fragmentation in inner suburban areas; these transitional sections are dominated by industrial land. The outer suburban areas showed the lowest degree of human disturbance and the lowest intensity of land use, with clear intent to improve its agro-ecological and forest network. ② In the longitudinal dimension, L represents the distance from the river edge. While the ecological integrity of 0≤L<100 m riparian buffer zone was well protected, from the river going outwards, the intensity of human disturbance was found to increase gradually. Landscape diversity and degree of fragmentation showed a similar trends of initial increase, then decrease; landscape fragmentation degree of the 300≤L<400 m riparian zone was the most significant.【Conclusion】Owing to disturbances from urban development activities, the landscape pattern of the Huangpu River riparian zone became fragmented, showing adverse edge effects at the water-land interface. The industrial land, production shelter forest land, and dry land are critical landscape typologies. The inner suburban riparian zone in the longitudinal direction, and the 300≤L<400 m riparian zone and its adjacent areas in the cross-sectional direction are priority areas for ecological restoration.
