%X 以遥感监测获取的土地利用/覆被数据构建的人类活动强度指数为监测人类活动的空间格局及其变化提供了一个便捷有效的工具，将其与区域经济产出相结合，可反映区域经济对土地利用扩张的依赖性及其空间格局。以汉江上游为案例区，将基于土地利用遥感监测构建的人类活动强度指数与区域经济产出和人口密度相结合，分析了人类活动强度的空间格局和县域经济产出对土地利用的依赖性。结果显示，人类活动强度指数反映出汉江上游人类活动强度与地形格局高度吻合；经济产出和人口密度与人类活动强度指数存在很好的回归关系，区域经济对土地利用扩张的依赖度较高。本研究也表明，HAIS能很好地反映通过土地利用面积扩张提高经济产出和人口承载量的人类活动强度，而对提高集约程度的土地利用变化难以反映。<br />
The Human Activity Intensity Index (HAIS) that combines land use/cover data and the impact of land cultivation on landscapes provides a convenient and effective tool for monitoring the spatial pattern of human activity intensity and its evolution. By combining the HAIS and economy indicators, the dependence of regional economy on the expansion of land cultivation can be reflected. In this study, the upper Han River basin was selected as case region. The land-use-based HAIS was combined with regional economic output and population density to reveal the spatial pattern of human activity and the dependence of county-level economic output on land use. The results revealed the human activity in the upper Han River basin highly coincided with landform pattern as reflected by the spatial pattern of HAIS. There was significant correlation between human activity intensity and population and regional economic output, which implies a high dependence of regional economy on land use expansion. This study also reveals that the HAIS is a suitable indicator reflecting the human activity by expanding the land use to promote the economic output and population carrying capacity, and however, is not sensitive to land use change by improving the land use intensity.
