摘要

By using GIS and RS techniques, landscape pattern dynamics of coal mine area of Shandong Province of China were studied from 1988 to 2008. The results showed that (1) Arable land could be taken on as the landscape matrix, as dominating in the landscape with the area percent of 91.71% in 1988 and 71.13% in 2008; construction land accounting for 7.65% in 1988 and 10.83% in 2008. The area of coal mining subsidence land increased from zero to 5300 hm2 markedly, and the area of mining land increased from 200 hm2 to 937.25 hm2 owning to coal mining work. (2) The number of land patches of the total landscape was 5982 in 1988 and 7798 in 2008, meanwhile mean patches area decreased form 5.19hm2 to 3.98hm2, which showed that the landscape fragment degree increased due to coal mining work, economy development and population increase. (3) The total area of arable land decreased 7024.28 hm2, of which 61.34% was subsidence land, 24.42% construction land, and 14.24% mining land that was the typical characteristics of land transition in coal mining area.
