摘要
湖泊生态缓冲带是一种隔离生境,可以更好地保护湖泊水体。如何确定缓冲带的宽度并对其进行科学管理,已成为学者与管理部门关注的热点之一。通过充分调研国内外现有研究成果,利用南京市土地利用图、植被分布图、水系分布图并结合无人机进行实际考察。根据不同湖泊保护目标的差异,结合湖泊周围土地类型,确定湖泊生态缓冲带的边界,有差别地将南京地区湖泊生态缓冲带划分为植被型、农田型、村落型、景区型、城镇型、水域型、堤防型、丘陵型,并利用SMB法结果结合土地利用实际状况,提出了不同类型湖泊生态缓冲带的建议宽度,以期为南京市湖泊生态缓冲带建设及其他湖泊生态缓冲带划定与构建提供参考。
The lake ecological buffer zone is an isolated habitat,which is used to protect the lake water body.How to determine the width of the buffer zone and scientific management has become one of the focuses of scholars and management departments.This paper made full scientific research on the existing research results at home and abroad,based on the land use map,vegetation distribution map,water system distribution map of Nanjing and combined with the UAV for actual investigation.Determined the boundary of the lake ecological buffer zone according to the difference of the protection objectives of different lakes and the land types around the lake.The lake ecological buffer zone in Nanjing was divided into vegetation type,farmland type,village type,scenic area type,town type,water area type,embankment type and hilly type.Based on the results of SMB method and the actual situation of land use,the suggested width of ecological buffer zone for different types of lakes was scientifically put forward.It s expected to provide reference for delimitation and construction of ecological buffer zone in other lakes.
