[目的]定量探求海河流域土地利用类型转换、变化强度与空间分布规律,以期为该地区土地利用的科学管理提供依据。[方法]在遥感技术与地理信息技术支持下,解译并绘制了研究区 40 年(1970~2010 年)5 期(1970 年、1980 年、1990 年、2000 年和 2010 年)的土地利用图,并以此为基础进行空间叠加构建了土地利用变化图谱、过程图谱、涨势图谱和演变模式 4 种图谱,分析了土地利用格局变化规律。[结果]整体上看,耕地转化为建设用地是40 年来海河流域最主要的土地利用变化特征;非稳定区域面积占到 35%,海河流域土地利用变化剧烈,加强土地科学管理十分必要;1980～1990 年期间各土地利用类型新增转化均最小,形成了增量波动低谷,表明在此时期土地利用类型之间转化最为平缓。[结论]该研究结果表明与常规转移矩阵法相比,地学信息图谱方法在土地利用变化分析方面有着明显优势,能够展示兴趣区的空间位置分布,表现出多维空间信息。
[Objective] The purpose was to quantitatively explore the land use type conversion, intensity of change and spatial distribution in Haihe River Basin, with a view to providing scientific basis for the scientific management of land use in the area. [Method] With the support of remote sensing technology and geographic information technology, the land use maps of the study area from 1970 to 2010 (1970, 1980, 1990, 2000 and 2010) were interpreted and plotted Based on this, four maps of land use change maps, process maps, upturn maps and evolution patterns were constructed, and the changing rules of land use patterns were analyzed. [Result] As a whole, the conversion of arable land to construction land was the most important characteristic of land use change in the Haihe River Basin in 40 years. The area of unstable area accounted for 35% and the land use change in Haihe River Basin was drastic. It was necessary to strengthen the scientific management of land. During 1990, the new conversion of land use types was the smallest, which led to the trough of incremental fluctuation, indicating that the transition between land use types was the most gradual during this period. [Conclusion] The results of this study show that compared with the conventional transfer matrix method, the geo-information atlas method has obvious advantages in the analysis of land use change and can display the spatial location distribution of interest areas and display multi-dimensional spatial information.
