Abstract:
The driving factors of spatial and temporal distribution of ecosystem services in Shandong province were analyzed, and the main factors of local ecosystem services being inhibited were found, so as to improve the productivity of forest, cultivated land and water system. Based on InVEST model, taking Shandong province as the research area, the quality of three ecosystem services, including water conservation, soil conservation and habitat quality, and the hierarchical function zone among three ecosystem services in 2010, 2015 and 2020 were evaluated. The results showed that: (1) The conversion of land use was mainly between grassland and cultivated land, and between cultivated land, forest land, water body and urban construction land. (2) Water conservation and soil conservation showed a trend of first decreasing and then increasing, and the habitat quality index decreased year by year. (3) The distribution of ecosystem services in Shandong province showed a zonal pattern, with a northeast-southwest trend, and the importance level of ecosystem services decreased gradually. The results indicated that the overall urbanization speed of Shandong province was obviously accelerating, the frequency of land use transformation was relatively fast, and the contradiction between man and land was intensifying.n speed of Shandong province was obviously accelerating, the frequency of land use transformation was relatively fast, and the contradiction between man and land was intensifying.n speed of Shandong province was obviously accelerating, the frequency of land use transformation was relatively fast, and the contradiction between man and land was intensifying.
