- Abstract:
-
Based on the data of Landsat TM images in 1990,2000 and 2010 of Linyi City, Markov transition probability matrix and geo-information TUPU theory were used to analyze the change of land use pattern in the past 20 years in Linyi City. By the CA-Markov model, the change of landscape pattern of Linyi City in 2020 was predicted. The results could be listed as follows. Firstly, although area of farmland kept decreasing, it still was dominant pattern of landscape in Linyi City. The area of construction land kept increasing, and shift of farmland to construction land was the main change trace. Secondly, farmland-farmland-farmland was the greatest area change of stable type atlas, which occupied largest area and widely spatial distributed. The area of repeated change type atlas was the smallest, which distributed sporadically. Lastly, the results of prediction in 2020 showed that the farmland would be the main source of land shift as before, which would be mainly converted to the construction land. The dominant pattern of landscape would be still farmland, and construction land would become the more important pattern of landscape. The area of woodland, waters, grassland and wasteland might have small changes, which could keep dynamic balance statues relatively. The results can provide the scientific basis for sustainable development of land and the balance between economy and ecology in Linyi City.
