摘　　要：[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 ] This study was to provide basis for the scientific management of land use in Haihe River Basin （HRB） through the quan- titative exploration of the land-use conversion,changes of intensity and spatial distribution in this region. [ Method ] With the support of remote sensing technology and geographic information technology, the land use maps of the study area in 40 years （1970-2010） were interpreted and drawn. Four kinds of Tupu, namely,land-use change Tupu,process Tupu, arising Tupu and evolution model Tupu were built through the spatial o- verlay of the land-use maps to analyze the change rules of land-use patterns. [ Result ] The conversion of arable land to construction land was the main characteristics of land-use changes in HRB for the 40 years：the area of non-stable region accounted for 35% of the total,indicating that the land use changed remarkably ,thus ,it was necessary to strengthen the scientific and land management in HRB ：the new conversions to all land-use patterns were all the lowest in 1980-1990,indicating that land use changed slowly during this period. [ Conclusion ] The results indicate that, com- pared with conventional transfer matrix method, geo-informatics Tupu has obvious advantage in analyzing land-use changes that it can demonstrate the spatial distribution of interest region,display the multi-dimensional spatial information.
