Land use transition of coal-based areas in Southeastern Junggar Basin and its impact on ecosystem service value
Taking the coal resource rich area in the southeast of the Junggar Basin as the study area,the ecosystem service value from 2005 to 2020 was evaluated by land use data,the spatial-temporal characteristics of land use transition and ecosystem service value were explored by spatial statistical methods,and the impact of different land use transition on ecosystem service value was further analyzed.The research results indicated that the land use transition in the study area was significant,with a large scale of conversion between grassland and unused land and a downward trend of total ecosystem service value,which mainly affected by the decrease in the value of ecosystem services in forests,grasslands,and water bodies;the global spatial positive correlation and clustering of ecosystem service value were significant but showed a weakening trend,with an increase in the low value clustering area of unused land;the conversion between grassland and unused land was the main reason for the change in ecosystem service value.To improve the ecosystem service value of the study area,it was suggested to maintain the stability of grassland and forest land,plan construction land reasonably and consider increasing water area,and strengthen the ecological utilization efficiency and ecological restoration measures of unused land.
