四川郫都林盤農(nóng)耕文化系統(tǒng)遺產(chǎn)地林盤空間分布特征及交通可達(dá)性

摘要：林盤是中國重要農(nóng)業(yè)文化遺產(chǎn)“四川郫都林盤農(nóng)耕文化系統(tǒng)”最主要的載體。以四川郫都林盤農(nóng)耕文化系統(tǒng)遺產(chǎn)地受保護(hù)的895個(gè)林盤為研究對象，利用GIS空間分析手段和數(shù)理統(tǒng)計(jì)方法，從分布類型、均衡性和空間格局角度定量研究郫都區(qū)林盤的空間分布特征，而后基于高德地圖API平臺測算了各林盤對于郫都區(qū)城市建成區(qū)中心的交通可達(dá)性。結(jié)果表明：1)郫都區(qū)林盤空間分布類型為凝聚型、非均衡分布態(tài)勢，呈現(xiàn)集群分布傾向；2)空間聚集形態(tài)上呈現(xiàn)為唐昌鎮(zhèn)為核心的高密度集聚圈、二處次級密度集聚圈以及東南部城市建成區(qū)的真空地帶；3)林盤交通可達(dá)性符合鄉(xiāng)村近郊旅游地單程耗時(shí)標(biāo)準(zhǔn)；4)相對平坦的地勢、道路等級及整體鄉(xiāng)村社會經(jīng)濟(jì)發(fā)展水平直接影響了林盤的交通可達(dá)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.
