Land Spatial Transformation Analysis in Shandong Province Based on Geo Information Map

It was of great practical significance to carry out the research on the transformation of land space for the comprehensive study and evaluation of the results of land space change, and to solve the coupling law between human activities and land space change system. Taking Shandong Province as the research area, supported by multi-stage remote sensing monitoring data, the spatial transformation characteristics of the province from 1980 to 2018 was analyzed by using GIS spatial analysis, geo information map and fluctuation potential map. The results showed that during the study period, the land of Shandong Province was dominated by agricultural production space, the expansion of urban living space was significantly higher than that of rural living space, the area of water ecological space and industrial and mining production space fluctuated, and the other ecological space areas continued to decline. From 1980 to 2000, Shandong Province was dominated by the transformation of agricultural production space to living space and ecological space to production space, while from 2000 to 2018 it was mainly the interactive transformation of living space and production space, production space and ecological space. The fluctuation map from 1980 to 2000 was mainly industrial and mining production space, agriculture and mining production space from 2000 to 2018, the total area of industrial production space and urban living space was increased by 3.42 times, of which rural and urban living space was increased by 4.29 times and 2.65 times, respectively. The area of urban living space decline map was low, while the shrinking area of rural living space continued to increase, and the ecological space shrinked rapidly. The research intuitively revealed the spatial-temporal evolution characteristics of land spatial transformation in Shandong Province, which could provide the basis for finding out the transformation law and carrying out the land spatial planning.
