【摘要】：本文以生态基础设施(EI)理论为指导,以富阳市建成区为对象,重点研究富阳市建成区绿地系统规划。本文结合实地调查并依据城市土地利用类型与开发程序的不同,将富阳市建成区的土地利用类型划分为建筑用地、交通用地、林地、耕地、水域和其它用地6类景观类型组成的分类体系,然后在GIS和Fragstats软件技术支撑下对研究区遥感影像进行分类解译,获得研究区景观类型图。首先对富阳市建成区进行景观格局分析,然后选取土地利用类型、坡度、坡向、高程、水域缓冲区和植被覆盖指数6个因子,将研究区划分为极敏感区、高度敏感区、中度敏感区、低度敏感区和非敏感区5个等级。利用层次分析法确定评价因子权重,应用GIS空间分析技术和因子叠加法完成研究区综合生态敏感性评价,结合景观格局指数,综合评价富阳市建成区生态敏感性程序及其空间分布情况。研究表明,富阳市建成区生态敏感性总体较高,5个敏感区面积比重分别为7.14%、18.95%、33.98%、20.17%、19.76%。在生态敏感性综合评价基础上,并以此规划出研究区生态安全的生态保护区、控制发展区、适宜发展区三类生态用地类型,进而提出了不同类型生态敏感区土地利用策略,并从区域整体景观出发,规划制定“一轴、三核、两环、四楔、八园、多链”的富阳市建成区绿地系统规划的总体布局。然后,基于生态基础设施(EI)的理论,从宏观和微观两个尺度对富阳市建成区绿地系统规划分别进行控制性规划与专项研究。在宏观尺度方面,重点研究了城市生态水基础设施、城市生态核心基础设施、城市生态廊道基础设施以及城市减灾基础设施;在微观尺度方面,重点研究富阳市具有典型性的生态景观要素类型,即富春江滨水廊道、黄公望山地森林公园和新沙岛湿地景观要素,对研究区三个景观要素进行详细专项规划与设计,为其他地区和城市绿地系统规划和评价提供模式和借鉴之用。
[Abstract]:Based on the EI theory of ecological infrastructure, this paper focuses on the planning of green space system in Fuyang City. Based on the field investigation and according to the different types of urban land use and the different development procedures, this paper divides the land use types of Fuyang City into construction land, traffic land, forest land and cultivated land. Based on GIS and Fragstats software technology, the remote sensing image of the study area was classified and interpreted, and the landscape type map of the study area was obtained. Firstly, the landscape pattern of the constructed area in Fuyang city was analyzed, and then the six factors of land use type, slope, slope direction, elevation, water buffer zone and vegetation cover index were selected to divide the study area into extremely sensitive area and highly sensitive area. There are 5 grades of middle sensitive region, low sensitive area and non sensitive region. Using AHP to determine the weight of evaluation factors, using GIS spatial analysis technology and factor superposition method to complete the comprehensive ecological sensitivity evaluation of the study area, combined with the landscape pattern index, A comprehensive evaluation of the ecological sensitivity program and its spatial distribution in Fuyang City. The results showed that the ecological sensitivity of the built-up area in Fuyang was high, and the area specific gravity of the five sensitive areas was 7.14 and 18.9533.98, 20.177.76, respectively. On the basis of comprehensive evaluation of ecological sensitivity, three types of ecological land types, namely ecological protection area, control development area and suitable development area, were planned for ecological safety in the study area, and the land use strategies of different ecological sensitive areas were put forward. Based on the overall landscape of the region, the overall layout of the green space system planning of Fuyang's built-up area is made, which is "one axis, three cores, two rings, four wedges, eight gardens and many chains". Then, based on the theory of ecological infrastructure (EI), the control planning and special research on the green space system planning in Fuyang are carried out from the macro and micro scale. On the macro scale, it focuses on urban ecological water infrastructure, urban ecological core infrastructure, urban ecological corridor infrastructure and urban disaster reduction infrastructure. Focusing on the typical types of ecological landscape elements in Fuyang, that is, the waterfront corridor of Fuchun River, Huanggongwang Mountain Forest Park and the wetland landscape elements of Xinsha Island, the three landscape elements of the study area are planned and designed in detail. For other regions and urban green space system planning and evaluation model and reference.
