摘要

绿道系统的建立具有重要的现实意义，其日益成为一种颇受欢迎的城市运动。近年来，中国掀起了建设绿道的热潮。福建省、市政府高度重视绿道建设，颁布了《福建省绿道网总体规划纲要》，计划在2020年实现绿道建设走遍福建。绿道建设主要分为省级、市级、县级，无论哪一级，耗资都非常巨大，影响规划的因素也很多，因此很有必要研究在现有条件的基础上快速进行科学选线的方法和工具。

本文以古田县县级绿道规划项目为背景，开展基于GIS的绿道网选线适宜性评价与实证研究，主要的研究内容包括：根据绿道选线原则和建设基础条件分析，采用GIS定量适宜性叠加分析法，提出一套较为普适的绿道选线因子评价体系。通过采用现场发放问卷调查和邮件发送等方式邀请专家打分确定每个因子的得分，然后编写计算因子权重的AHP 程序，进而利用GIS软件的空间分析建模模块对评价因子图层数据进行加权叠加分析，得到适宜性分析结果。最后，利用上位规划即市级规划布线和专家推荐点作为适宜性评价结果图验证资料，验证了评价方法与结果的合理性。

ABSTRACT

ABSTRACT

Greenway construction has become a popular city movement, establishment of the greenway system, has important practical significance. In recent years, China set off a greenway construction boom. Fujian Province, City Hall attaches great importance to greenway construction, promulgated the "Fujian greenway network planning outline", plans in 2020 to achieve greenway construction through Fujian. Greenway construction is divided into provincial, municipal, county, no matter what level, cost is very huge, is also a lot of influence planning factors, so it is of scientific methods and tools necessary to study fault line selection based on the existing conditions.

Based on the background of Gutian County of greenway planning project, to carry out GIS based greenway network line selection suitability assessment and the empirical research, the main research contents include: according to the greenway line selection principle and basic construction condition analysis, using GIS quantitative suitability overlay analysis method, puts forward a set of more universal greenway line selection factor evaluation system. By using questionnaire survey and on-site distribution to send mail to invite experts to determine each factor score, and then write the factor weights are calculated by AHP program, then use the GIS software spatial analysis model of assessment factor layer data were weighted overlay analysis, get the suitability analysis results. Finally,using the master planning of municipal planning wiring and experts recommend as the suitability evaluation results of validation data to verify the rationality of the evaluation method and results.
