- Abstract:
- The special karst natural geographical environment in the karst area of central Guizhou forms a mountainous city. In order to explore the particularity of the urban expansion mode and urban ecological problems under the background of urbanization, the typical mountainous city in central Guizhou—Anshun City was selected as the sample. Based on three high-resolution satellite images in 2007, 2012 and 2017, combination of field investigation and related planning inquiry, the spatial and temporal variation characteristics of landscape pattern in Anshun City in the past 10 years were analyzed. The results show that:(1)the area of built-up area of Anshun City had expanded 2.4 times in the past 10 years, showing a trend of gradual accelerated expansion;(2)urban space expansion can be summarized as the pattern of ‘flooded network expansion mode';(3)cultivated land was the main contributor to urban expansion, land economy driven by real estate industry was the main driving factor on urban expansion. These results can provide the basic reference for the follow-up study and have guiding significance for the urban construction work of Anshun City.
