Land use transformation and its ecological environment effects based on the"production-living-ecology"spaces:taking Shandong Province as an example
Using remote sensing image data from 1980s,1990,2000,2010 and 2020 in Shandong Province as data sources,the spatio-temporal changes and transformation characteristics of land use in Shandong Province from the perspective of"production-living-ecology"spaces was analyzed by use of land use dynamic attitude and the land use transfer matrix,and a quantitative analysis of the ecological environment effects of land use transformation in Shan-dong Province was conducted by use of ecological environment quality index and ecological contribution rate.The re-sults showed that the geographical distribution of the"production-living-ecology"spaces varied significantly,the production space was widely distributed,with the area of land for agricultural production land being the largest,the living space showed a continuous expansion trend,and the ecological space was mainly distributed in the hilly areas of the south-central and eastern Shandong;the most prominent issue in land use transformation was the encroach-ment of urban and rural living land on land for agricultural production caused by the expansion of the cities and coun-ties;the quality of the ecological environment showed a fluctuating downward trend,with an overall pattern of"highest in the east,higher in the center and low in the west";the improvement of ecological environment and deteri-oration of ecological environment co-existed,and the degree of deterioration was greater than that of improvement.
