| 摘 要： | 采用≥10℃积温为指标划分的自然带，从土地利用结构和土地利用程度两方面，以垦殖率、土地产出、城市个数、城市建成区用地水平、土地利用程度和破碎度等为指标，构建了土地利用/覆盖格局分析的指标体系，通过自然单元和社会经济单元的数据匹配，量化土地利用/覆盖在不同自然带上的差异，从而分析中国东部南北样带上的土地利用/覆盖格局，以期为分析土地利用/覆盖变化及其驱动机制提供科学依据。

| Abstract: | In this paper, North-south Transect of Eastern China (NSTEC) is compartmentalized into 8 physical regions with the accumulative temperature as the index. Based on the 8 physical regions, cultivation rate, land output, city number, city land use degree, land use fragmentation and land use degree as indexes are adopted to build up the index system of Land Use and Cover Change (LUCC) pattern by considered land use structure and land use degree. Through data transforming between natural pixel and social economic pixel, this paper illustrates differences of LUCC on physical regions quantitatively, and analyzes LUCC pattern in NSTEC in order to offer some science evidences for LUCC pattern analysis and its driving force. Finally, we find that agriculture activities are the most important among the human activities, which are the strongest in the south warm zone and north sub tropic zone, are lighter in the northern than southern. |
