武汉市耕地景观游憩功能与可达性的空间匹配格局

揭示耕地景观游憩功能的供给能力与其可达性的空间匹配格局,可以为耕地景观游憩功能的合理布局、开发与利用提供依据。以武汉市为例,采用指标评价法和专家打分法,结合GIS空间分析,建立了耕地景观游憩功能的空间格局研究框架,对耕地景观游憩功能的供应潜力、可达性、及两者空间匹配等方面开展了研究。结果表明:(1)武汉市耕地景观游憩功能供应潜力的空间分布呈现从中心城区边缘向外逐渐降低的格局;(2)武汉市耕地景观游憩功能可达性呈现"中西部高,边缘低"的分布格局;(3)根据耕地景观游憩功能的供应潜力与可达性的空间匹配关系,将武汉市耕地景观游憩服务分为四类:高供应-高可达,高供应-低可达,低供应-高可达,低供应-低可达;这四类面积分别占研究区域的26.17%、25.24%、17.33%、31.26%。对耕地景观游憩功能的合理开发与利用、促进耕地利用的多功能化具有重要的现实意义。

RESEARCH ON THE SPATIAL MATHCHING PATTERN OF CULTIVATED LAND LANDSCAPE RECREATION FUNCTION AND ACCESSIBILITY IN WUHAN

Revealing the spatial matching pattern of supply capacity and accessibility of cultivated land landscape recreation function can provide the basis for rational distribution, development and utilization of cultivated land landscape recreation function. Taking Wuhan as an example, this paper used the index evaluation method and expert scoring method, combined with spatial analysis, to establish the research framework of spatial pattern of cultivated land landscape recreation function in Wuhan, from the supply potential of farmland landscape recreation function, accessibility and their spatial match. The results showed that:(1) The spatial distribution of the cultivated land landscape recreation supply potential in Wuhan is gradually decreasing from the center of the city edge; (2) The accessibility of cultivated land landscape function in Wuhan generally shows a distribution pattern of "mid-west high, edge low"; (3) According to the spatial matching of supply potential and accessibility, the cultivated land landscape recreation service in Wuhan is divided into four categories:high supply-high accessibility, high supply-low accessibility, high accessibility-low supply and low accessibility-low supply; and these four categories accounted for 26.17%, 25.24%, 17.33%, and 31.26% of the research area, respectively. The study of the cultivated land landscape recreation function has important practical significance on reasonable development and utilization of cultivated land resources, promoting multi-functional use of cultivated land.
