LAND USE TRANSFORMATION AND ECOSYSTEM SERVICE VALUE FROM THE PERSPECTIVE OF “PRODUCTION-LIVINGECOLOGICAL SPACE”: A CASE STUDY OF HEILONGJIANG PROVINCE (CHINA)

Analyzing changes in land use and estimating ecosystem services is essential to directing the wise use of local land resources and encouraging environmental preservation.This study focuses on Heilongjiang Province (China), utilizing remote sensing data from 2000, 2010, and 2020 as the primary data source.A "Production-Living-Ecological Space" framework is established, encompassing four dimensions: ecological space, ecological production space, production ecological space, and living production space.Land use transition features of the study area were thoroughly examined, as well as temporal shifts in ecosystem service value based on Xie Gao Di's and other researchers' guidance.Based on our research, the following shows: (1) Over the past two decades, the area of ecological production space in Heilongjiang Province initially expanded and subsequently declined, while the areas of production ecological space and living production space consistently increased.Nonetheless, the overall trend stabilized in the ecological space area.(2) During this period, the total value of ecosystem services in the study area exhibited a downward trend, with a cumulative decrease of 162.392 billion yuan.The value of land ecological services in ecological space, living, and production space decreased, whereas the value of ecological production space initially increased and later declined.Conversely, the value of production ecological space showed an upward trend.(3) The complementary pattern of ecosystem service values in Heilongjiang Province underscores the significant role of forest land, a critical component of ecological space, in maintaining the overall ecosystem service value.(4) To preserve the stability and health of the ecosystem, Heilongjiang Province has to focus on the coordinated development of "Production-Living-Ecological Space".Through scientific and rational land use planning and policy adjustment, it is important to balance the relationship between economic development and ecological protection, and promote the sustainable development of ecological system.
