中文摘要:
      以海口市中心城区为研究对象,在查阅资料和现场调研的基础上,选取土地利用类型、可达性、景观资源、坡度、绿地斑块面积、水系分布和道路分布7个因素作为绿道选线适宜性评价因子.首先通过专家打分法和问卷调查法,结合层次分析法(AHP)确定每个因子的权重,然后使用ArcGIS对各因子执行单因子分析,并利用栅格计算器根据每个因子权重的不同,分层叠加,最终获得海口市中心城区绿道选线的不同适宜性范围,并为实际城市绿道选线提供依据.
英文摘要:
      Greenway plays an important role in the construction and development of a city. In terms of ecology, greenway relieves the city"s ecological pressure and optimizes the city"s regional features. In urban construction, greenway plays an important role in urban structure optimization by connecting urban space. Finally in humanities, the existence of greenway improves the living quality of residents and makes cities more suitable for human habitation. In this paper, the central urban area of Haikou city was taken as the research object. On the basis of data access and field investigation, 7 factors were selected as the evaluation factors for the suitability of greenway selection: land use type, accessibility, landscape resources, gradient, green space patch area, water system distribution and road distribution. Firstly, the weight of each factor was determined through the combination of expert scoring method and questionnaire survey and AHP method. Then the single factor analysis of each factor was performed by ArcGIS, and the layers of each factor were superimposed according to the weight of each factor by raster calculator to obtain different suitable ranges of greenway selection in central district of Haikou city, so as to guide greenway selection.
