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。
To reveal the spatial matching pattern between the supply capacity of recreational functions and the reachability of cultivated land landscape can provide the basis for the reasonable layout, development and utilization of recreational functions of cultivated land landscapes. Taking Wuhan as an example, this paper establishes a research framework of the spatial pattern of recreational functions of arable land with spatial analysis based on index evaluation method and expert scoring method. It provides a spatial analysis of the potential supply, accessibility and spatial matching of recreational functions of arable land And other aspects of research. The results showed that: (1) Spatial distribution of the potential supply of recreational functions of cultivated land in Wuhan showed a pattern of decreasing gradually from the edge of the central urban area; (2) The accessibility of recreational functions of cultivated land in Wuhan showed "high midwest and low margins (3) According to the spatial matching relationship between supply potential and accessibility of recreational function of cultivated land landscape, the recreational services of cultivated land in Wuhan are divided into four categories: high supply, high availability, high supply, low availability Up to low supply - high reachable, low supply - low reachable. These four categories accounted for 26.17%, 25.24%, 17.33% and 31.26% of the study area respectively. It is of great practical significance to develop and utilize the recreational function of cultivated land landscape in a rational way and to promote the multi-functionalization of cultivated land use.
