Abstract

Abstract:

A vegetable market is a crucial element of an urban landscape, and its well-planned layout is essential for implementing the “vegetable basket” project. This study focuses on vegetable markets in the main urban area of the Lanzhou City using POI were obtained by AmAP and socioeconomic data in the statistical yearbook from 2020. This study uses various analytical methods such as kernel density analysis, exploratory spatial data analysis, two-step mobile search method, and geographic detector, and others through big data analysis from a geographical perspective to explore the spatial distribution characteristics and factors influencing vegetable markets in Lanzhou City. The findings indicate that vegetable markets in Lanzhou City are mainly distributed in a “northwest to southeast” direction. Meanwhile, comprehensive hypermarkets in the main urban area of the Lanzhou City exhibits a more balanced and dispersed distribution than other market types. By contrast, large- and medium-sized farmers’ markets and vegetable retail stores are more concentrated. Regarding quantity scale, vegetable market shows a distribution pattern of being sparse in the east, west, and north and dense in the south. The distribution of comprehensive large supermarkets is patchy, the overall distribution of large and medium-sized farmers’ markets is island distribution and multi-center pattern, and the spatial distribution of vegetable retail stores is spotty distribution. The spatial distribution of vegetable markets exhibits a strong clustering trend. Although the accessibility of vegetable markets in Lanzhou City is generally good, some streets in the Anning and Xigu Districts have low accessibility. This study identifies multiple factors influencing the spatial distribution of vegetable markets in Lanzhou City, with population and traffic being the main factors. Additionally, the study highlights the unreasonable spatial distribution of vegetable markets and provides relevant suggestions for strengthening the rational spatial distribution and coordinated development of vegetable markets in Lanzhou City.

Key words: vegetable markets, GIS spatial analysis, geographical detector, Lanzhou City
