Abstract
Land use/cover change (LUCC) and ecosystem service functions are current hot topics in global research on environmental change. A comprehensive analysis and understanding of the land use changes and ecosystem services, and the equilibrium state of the interaction between the natural environment and the social economy is crucial for the sustainable utilization of land resources. We used remote sensing image to research the LUCC, ecosystem service value (ESV), and ecological economic harmony (EEH) in eight main urban areas of Harbin in China from 1990 to 2015. The results show that, in the past 25 years, arable land—which is a part of ecological land—is the main source of construction land for urbanization, whereas the other ecological land is the main source of conversion to arable land. There is no significant change in the value ratio of ESV, however, it is also inclined to the southeast of the study area in spaces like the barycenter of LUCC. The EEH degree has risen from the potential crisis area to the medium coordination degree, and then dropped to the low coordination degree. This shows that although there has been limited change of LUCC, ESV, and EEH in eight main urban areas of Harbin in 25 years, there is a contradiction between the allocation of ecological land and non-ecological land.

The definition of the use of environmental resources changes with the advancement of society and human needs
In the 1990s, the International Geosphere-Biosphere Program (IGBP) and the International Human Dimensions Program on Global Environmental Change (IHDP) jointly developed and published the Scientific Research Plan of land use/cover change (LUCC) [7,8,9], which focuses on the mechanisms of land use and land cover change, and integrated models at regional and global scales
The proportion of construction land area in non-ecological land has increased over 25 years by 1.10% overall, without any change in bare land
Summary
The definition of the use of environmental resources changes with the advancement of society and human needs. Resource depletion will lead to the degradation of the environment and various ecological service functions, inhibiting the advancement of society and human needs [1,2,3,4,5,6]. Many international organizations and countries working on global environmental change have undertaken research and initiated their own LUCC research projects. The goal of these policies and efforts is to protect and restore the ecological environment in parallel with economic development, to promote synergistic development of the economy and the ecological environment, and to emphasize the “value” of ecological land
