摘要
Improving the supply-demand balance of ecosystem services(SDBES)from the perspective of land use is essential for managing regional ecosystem and realizing sustainable development.By combining land use with the supply and demand of ecosystem services(SDES),a technical framework for defining land use threshold and optimizing its structure to improve the SDBES state was constructed and applied to a practical case.The spatial pattern of supply and demand of each ES in Lancang county was distinctly heterogeneous,with significant differences in SDES across different land use types.Strong spatial heterogeneity existed in the ESDR of each ES at the grid scale,and the areas of deficit were ranked as carbon sequestration>water conservation>habitat quality>food production.The structure of dry land,paddy field,tea,evergreen broad-leaved forest,grassland,urban construction land,and industrial and mining construction land were the focus of land use optimization.Based on the land use area thresholds under the SDBES,the optimal land use structure for maximizing comprehensive benefits contributed to a balanced relationship between SDES and promoted sustainable regional development.The study provides a new perspective and method for improving the SDBES state,alleviating land conflicts,and managing ecological environment.
