黄河中下流域都市群の土地被覆変化と都市化特徴に関する研究: 中国鄭州市・開封市・中牟県を対象として

摘要

中国は、1970年代末の「改革・開放，政策に上り、東部沿海地 域は飛躍的な発展を遂げ、中国全体に急速な経済発展をもたらし、 都市化も急速に進んでいる。%The purpose of this study is to estimate land coverage change and the characteristic of urbanization in city agglomeration in the middle and lower of Yellow River valley using Landsat data and the survey data of land use condition. Firstly, we created the maps of the land coverage classification, and found the actual situation of the land coverage. Secondly, we investigated the change of the built-up area by the Kernel Density Presumption method, and analyzed the effect from traffic infrastructure, maked the characteristic of the urbanization clear. Finally, we analyzed the change of NDVI and concluded the characteristic of the urbanization in the city agglomeration.
