摘　　要：土地利用转型研究是当前研究热点,坝子是以高原山地为主的贵州省人类活动最为显著的区域,探讨贵州省坝子以耕地为主的土地利用转型与功能演变两者之间的相互作用关系具有重要意义。以1966~2016年的高分辨率遥感影像为主要数据源,结合实地调查,建立坝子土地利用功能分类体系,以贵州典型坝子涟江坝子为例,进行了坝子土地利用显性和隐性转型实证研究。结果表明:从1966~2016年,坝子经历了土地利用的显性转型和隐性转型,耕地转型与功能演变相互协同耦合变化阶段特征明显,其实质是坝子社会经济发展阶段转型下资源配置方式的转变主导而成。案例研究表明贵州坝子土地利用转型总体可分为粗放式阶段、粗放式向集约化过渡阶段、逐步集约化阶段和集约化增强阶段。"个体、政府和市场"3个层面和"文化、制度、社会经济、人口技术区位"4个重要因素是坝子土地利用转型的驱动控制系统。Land use transformation research is the current research hotspot and is the most significant area of human activities in Guizhou Province, which is dominated with plateau and mountains. Hence, it is valuable to investigate the interaction between the land use transformation and functional evolution based on arable land in Guizhou Province. Based on the high-resolution remote sensing images during 1966-2016 and field investigations, the present study established the classification system of the function of the land use in the basin and performed the empirical study on the dominant and implicit transition of dam land use, such as the typical basin of Lianjiang in Guizhou. The results can be summarized as follows: from 1966 to 2016, the basin mainly experienced dominant and implicit transformations of land use;the characteristics of the cooperative transformation of cultivated land transformation and functional evolution are obvious, which is dominated by the transformation of resource allocation mode under the transformation of the social and economic development stage of the basin. Case studies suggested that the land use transformation of Guizhou basin can be divided into extensive stages, extensive transition to intensive, gradual intensification and intensification. The three important factors, i.e, "individual, government and market", "cultural, institutional, socio-economic, and population technology", are the driving control systems for the land use transformation of the basin.
