- Abstract:
-
Multi-seasonal TM, ETM+ and OLI remote sensing images data of Jaozuo City in 1988, 1993, 2001, 2004, 2010 and 2014 were classified by using Random Forests algorithm. The dynamic of land use/cover was then obtained and related to the main driving factors. The results showed that:(1) DEM was more important than other variables during the process of classification, especially for forest; (2) the area of agricultural land reached the maximum in 1993, construction area increased doubled in the past 26 years, but the growth rate slowed the slowdown trend in recent years, while forest area only increased in recent years; (3) the bare land and farmland experienced the most dramatic change during the period from 1993 to 2001, the annual decrement of agricultural land and forest land was the largest during the period from 2001 to 2004, and the construction land increased the most rapid in 3 years, the annual change was the largest during the period from 2010 to 2014 in terms of all the land uses/covers; (4) the contruction land and agricultural land were mainly located in the middle and eastern regions due to the constraint of topography. The bare land and population density showed the significantly negative correlation (p < 0.01). The 1% increase of GDP resulted from 0.12% increase of oconstruction land area in Jiaozuo City. This study indicates that farmland should be protected to meet food demand during the process of industrial transformation.
