摘要: 以贵州省贞丰县2010—2020年耕地数据为对象,运用核密度和转移矩阵法对岩溶山区耕地时空演变及影响因素进行分析。结果表明,2010—2020年,耕地面积由56 754.16 hm2减少至39 715.85 hm2,共减少17 038.31 hm2,破碎化程度加剧。研究期内,耕地主要转化为林地、园地,主要发生于研究区中部的白层镇、鲁容乡和鲁贡镇一带;其次建设用地持续占用耕地,加速耕地面积减少。自然因素和社会因素共同影响耕地面积分布及其变化;耕地主要分布于坡度6°~25°及道路和居民点缓冲带100 m范围内。

关键词: 耕地, 时空演变, 影响因素, 岩溶山区

Abstract: The spatial-temporal evolution and influencing factors of cultivated land in the karst mountainous area were analyzed using kernel density and transfer matrix methods with cultivated land data of Zhenfeng County, Guizhou Province from 2010 to 2020 as the object. The results showed that from 2010 to 2020, the cultivated land area decreased from 56 754.16 hm2 to 39 715.85 hm2, a total decrease of 17 038.31 hm2, and the degree of fragmentation increased. During the study period, cultivated land was mainly converted into forest and garden land, which mainly occurred in the central part of the study area around Baiceng Township, Lurong Township, and Lugong Township, followed by the continuous occupation of cultivated land by construction land, which accelerated the reduction of cultivated land area. Natural and social factors jointly influenced the distribution of cultivated land and its changes, and cultivated land was mainly distributed on slopes of 6° to 25° and within 100 m of the buffer zone of roads and settlements.

Key words: cultivated land, spatial-temporal evolution, influencing factors, karst mountainous area
