摘要: 为揭示南宁市土地利用的时空变化规律,运用地理信息系统(Geographic information system,GIS)技术和土地利用动态度、利用程度和转移矩阵等方法,深入分析1990—2020年南宁市土地利用的时空演变特征。结果表明,1990—2020年南宁市各土地利用类型的变化明显、土地利用变化的总体速度加快,建设用地和未利用地增加且表现为增速,耕地、林地、草地和水域减少且表现为减速;南宁市的土地利用程度处于中等水平,随着人为活动对土地的不断干扰和影响,土地利用程度水平呈逐渐升高的趋势;30年间南宁市共有1 051.61 km2的土地利用类型发生转移,其中建设用地和未利用地表现为净转入特征,耕地、林地、草地、水域表现为净转出特征。

Abstract: In order to reveal the spatio-temporal changes of land use in Nanning City, the spatial-temporal evolution characteristics of land use in Nanning City from 1990 to 2020 were analyzed in depth by using geographic information system (GIS) technology and methods such as land use dynamics, degree of utilization and transfer matrix. The results showed that from 1990 to 2020, the changes of land use types in Nanning City were obvious, the overall speed of land use change was accelerated, the construction land and unutilized land increased and showed a growth rate, and the cultivated land, forest land, grassland and water area decreased and showed deceleration; the degree of land use in Nanning City was at a medium level, with the continuous disturbance and influence of human activities on the land, the level of land use degree showed a gradually increasing trend; during the 30 years, a total of 1 051.61 km2 of land use types in Nanning City had been transferred, of which the construction land and unutilized land showed a net transfer in, and the cultivated land, forest land, grassland and water area showed a net transfer out.

Key words: land use, temporal and spatial changes, dynamics, degree of utilization, transfer matrix, Nanning City
