Abstract:

Based on the land use data of seven periods in Shandong Province, included 1970s, 1980s, 1995, 2000, 2005, 2010 and 2015, used the land use dynamic degree, structural change and land use type transfer matrix to study the ecological environment change caused by human land use activities. The results showed that the land use types change greatly from 1970s to 2015 in Shandong Province, except for the rapid increase of construction land, cultivated land, forest land, grassland and unused land were all decreased in different degrees, and cultivated land was the main type of land. The increase of information entropy, the decrease of dominance and the increase of equilibrium indicated that the difference of land use types was reduced, and the dominance of single land use type was decreased; the dynamic degree of comprehensive land use was 0.12, which belonged to the very slow type of land use. In the single land use dynamic degree, cultivated land, forest land and grassland were used very slowly. The dynamic degree of construction land in construction land was 7.07, which changed the most in the dynamic degree of construction land. The change of land use type mainly showed that cultivated land turned to construction land, water area and unused land turned to cultivated land and construction land, and water area turned to unused land. Cultivated land and grassland had significant negative correlation with GDP(X1), primary industry(X2), secondary industry(X3) and tertiary industry(X4); construction land had significant positive correlation with X1, X2, X3 and X4; unused land had significant negative correlation with X1, X2 and X3.
