以徐州市城区公共绿地为研究对象,通过网上、图书馆、书店等多种渠道,收集研究区域的文献、图片、遥感影像等资料,对城市公共绿地进行数字化处理,缓冲区分析

[摘要]:公共绿地作为城市的重要组成部分,具有非常重要的生态功能和社会功能,但是早期的评价公共绿地的的指标因为技术的原因,不能科学的准确反映出公共绿地的类型和空间分布。借助RS和GIS技术,可以对城市公共绿地进行良好分析和评价,有利于科学的规划和管理城市公共绿地。本文以徐州市城区公共绿地为研究对象,通过网上、图书馆、书店等多种渠道,收集研究区域的文献、图片、遥感影像等资料,对城市公共绿地进行数字化处理,缓冲区分析,统计整理分析,获得城市人均公共绿地,空间分布、服务面积和可达性分析等结果。研究结果表明徐州的主城区公共绿地空间布局总体较为合理,基本满足了居民的日常休憩娱乐功能,但是,市区西北部、东部城市公园绿地较为缺乏。另外,公共绿地空间分布总体呈由中心向外围逐渐递减的趋势,且城市中心的公共绿地面积偏小,数量较多、分布比较零散,研究区域的公共绿地多分布和人口密集的区域成正相关性。在道路、建筑、水体附近,公共绿地的数量明显教多、面积也较大。研究结果以期对今后的规划和建设提供依据,给徐州市城区的公共绿地的建设和长期发展提供一些合理化建议。32518

[Abstract]: As an important part of city public green space, with ecological and social function is veryimportant, but the early evaluation of public green space for technical reasons, can notaccurately reflect the scientific type and spatial distribution of public green space. With the help of RS and GIS technology, can be a good analysis and evaluation of city public green space, is conducive to the planning and management of city public green space science. In 2015 Xuzhou city public green space as the research object, through the Internet,libraries,bookstores,and,other Scientific planning can meet the needs of the residents for recreation.channels, collecting documents, pictures, the study area of remote sensing image data, in the process of digital city public green space, buffer analysis, statisticalanalysis, obtain the city public green land per capita, the spatial distribution, service area andthe reachability analysis etc.. The results show that urban public green space layout in Xuzhou is more reasonable, basically meet the residents' daily leisure and entertainmentfunction, however, north-west of the city, the eastern city parks lack. In addition, the public green space distribution from the center to the periphery showed a gradual decreasing trend,and the area of public green space in the center of the city, a large number of small,scattered distribution, regional distribution and public green space more densely populated areas have a positive correlation. Near the road, buildings, water bodies, the number of public green area is larger, more obvious. The results of the study in order to provide the basis for planning and construction in the future, to the construction of the Xuzhou city public green space and long-term development to provide some reasonable suggestions.
