四川郫都林盘农耕文化系统遗产地林盘空间分布特征及交通可达性

摘要：林盘是中国重要农业文化遗产“四川郫都林盘农耕文化系统”最主要的载体。以四川郫都林盘农耕文化系统遗产地受保护的895个林盘为研究对象，利用GIS空间分析手段和数理统计方法，从分布类型、均衡性和空间格局角度定量研究郫都区林盘的空间分布特征，而后基于高德地图API平台测算了各林盘对于郫都区城市建成区中心的交通可达性。结果表明：1)郫都区林盘空间分布类型为凝聚型、非均衡分布态势，呈现集群分布倾向；2)空间聚集形态上呈现为唐昌镇为核心的高密度集聚圈、二处次级密度集聚圈以及东南部城市建成区的真空地带；3)林盘交通可达性符合乡村近郊旅游地单程耗时标准；4)相对平坦的地势、道路等级及整体乡村社会经济发展水平直接影响了林盘的交通可达性。

Abstract: Sichuan Pidu Linpan farming culture system, which is the part of Nationally Important Agriculture Heritage Systems, are mainly carried by Linpan. Taking 895 protected Linpan in the heritage site of the Sichuan Pidu Linpan Cultural System as the object. Using GIS spatial analysis methods and mathematical statistical methods to quantitatively study the spatial distribution characteristics of the Linpan in Pidu District from the perspective of distribution type, balance and spatial pattern. Then, based on the Gaode Map API platform, the traffic accessibility of each Linpan to the urban built-up area of Pidu District was calculated. The results are as follows: 1)The spatial distribution type of Linpan in Pidu District is a cohesive, non-equilibrium distribution, showing a tendency of cluster distribution. 2) The spatial aggregation form is a high-density agglomeration circle with Tangchang Town as the core, two secondary-density agglomeration circles and the vacuum zone of the urban built-up area in the southeast. 3) The accessibility of the Linpan traffic meets the one-way time-consuming standard of tourist destinations in rural areas. 4) The relatively flat terrain, road grade, and overall rural social and economic development level directly affect the transportation accessibility of the Linpan.
