Abstract:
Based on the three period remote sensing images of Guanzhong-Tianshui economic zone in 2000,2005 and 2010,CA-Markov model was used to forecast the land use pattern in 2015.The results show that the precision of the model is fairly high with the Kappa coefficient of 0.79.In 2005—2015, the arable land and forest land will reduce while the construction land will increase conspicuously, meanwhile the meadowland and water just have a slight change and the unutilized land nearly have little change in Guanzhong-Tianshui economic zone. The ecological environment of the study area deteriorate and it′s essential to protect the arable land and forest land.
