摘要: Settlements and cultivated land are important production and living spaces in promoting rural revitalization. However, few studies have explored the relationship between rural settlements and cultivated land from spatiotemporal interaction perspective. This paper analyzed the spatiotemporal conversion and the interactive mechanism between rural settlements and cultivated land in a karst mountainous area (Qixingguan District of Guizhou Province) with fragile ecological environment in China during 2009-2018. The results showed that the expansion of rural settlements and the loss of cultivated land coexisted in Qixingguan District. Only 2.68% of the new cultivated land was reclaimed from rural settlements, whereas 85.45% of the new rural settlements occupied cultivated land. Six spatial expansion modes of rural settlements when occupying cultivated land were identified. Among these six modes, the area of the edge-expansion & along traffic roads (EA) mode accounted for 52.75%. The occupation by rural settlements made the cultivated land landscape more fragmented. The area ratio index of cultivated land to rural settlements (ARICR) of Qixingguan District averaged 18.75 in 2009 and 17.21 in 2018, respectively. The ARICR reduced in all township administrative regions. Cultivated land with suitable slope condition for farming or without rocky desertification was more likely to be occupied by rural settlements. The probability of cultivated land occupied by rural settlements increased with the decrease of the distance to traffic roads, towns, and old rural settlements. The better the economic and social development of the township administrative regions, the more the ARICR decreased, while the richer the agricultural resources and the better the rural development of the township administrative regions, the less the ARICR decreased. The optimal reconstruction path of rural settlements, the comprehensive conservation path of cultivated land and the urban-rural integration development path in karst mountainous area were proposed. The findings would contribute to our understanding of the spatiotemporal interaction between rural settlements and cultivated land, and would provide a theoretical basis for promoting the coordinated development of rural man-land relationship and rural revitalization in karst areas.
