城市土地扩张与人类活动密切相关并与人类活动相互作用。尽管广泛的研究调查了城市土地扩张的特征和模式，但城市土地扩张与人类活动之间的耦合已被忽略。因此，本文探讨了根据Landsat和Night Time-Time Light遥感数据的1995 - 2015年期间，在1995 - 2015年期间，中国长江经济带（The Yreb）中的城市土地扩张与人类活动范围之间的关系。总体而言，城市土地与大都市地区的人类活动范围与城市聚集的范围之间存在耦合。一方面，随着时间的流逝，城市土地与人类活动范围之间的匹配程度具有向上的趋势。根据我们的回归模型和景观指数的结果，城市土地以外的人类活动范围与城市土地的幅度有关，在发达地区，城市土地以外的人类活动范围内的土地发生了更大的变化。另一方面，通过计算匹配程度并根据位置关系来确定匹配程度并确定三种城市土地扩展类型，从而证明了新增加的城市土地与人类活动范围之间的耦合。本文认为，尽管匹配程度增加了，而主要的城市土地扩张类型也从偏远地区转变为回填，但城市土地的不当扩展以及空间分布和规模结构的不平衡发展仍然存在。结果可用于制定合理的政策和计划，并促进城市土地和人类活动的区域融合和协调的发展。
Urban land expansion is closely related to and interacts with human activities. Although extensive studies have investigated the characteristics and patterns of urban land expansion, the coupling between urban land expansion and human activities has been neglected. Therefore, this paper explores the relationship between urban land expansion and the scope of human activities in the Yangtze River Economic Belt (the YREB) of China during the period of 1995-2015 based on Landsat and nighttime light remote sensing data. Overall, a coupling exists between urban land and the scope of human activities at the scales of the metropolitan area and the urban agglomeration. On the one hand, the degree of match between urban land and the scope of human activities has an upward tendency with time. According to the results of our regression model and landscape indexes, the scope of human activities outside urban land is associated with the magnitude of urban land, and the land within the scope of human activities outside urban land changed more intensely in developed areas. On the other hand, a coupling between newly increased urban land and the scope of human activities was proven by calculating the degree of match and identifying three urban land expansion types based on the location relationship. This paper argues that although the degree of match increased and the dominant type of urban land expansion transformed from outlying to backfilling, the problems of disorderly expansion of urban land and imbalanced development of the spatial distribution and scale structure still exist. The results can be used to formulate reasonable policies and planning and to promote the regional integration and coordinated development of urban land and human activities.
