Research on Coupling and Coordination of Land Ecological Security and Socioeconomic Development in Ganjiang River Basin
Taking counties as research object,this paper constructed two evaluation index systems of land ecological security and socioeconomic development,and a model of their coupling and coordination in Ganjiang River basin.The results indicated that both the land ecological security index(LESI)and the socioeconomic de-velopment index(SEDI)in Ganjiang River basin showed an"N"-shaped development trend from 2000 to 2020,and the coupling and coordination degree(CCD)showed a fluctuating upward trend in structure,its Moran's index significantly increased,indicating that it had a significant spatial agglomeration characteristic,with the cold spots mainly concentrated in the upstream hilly area,and the hot spots mainly concentrated in the downstream plain area.The primary obstacle to the coupling and coordination degree in Ganjiang River ba-sin had undergone ecology,economy and healthcare changes.The low level development of socioeconomic sys-tem was the biggest constraint affecting coupling and coordination degree.It should be further strengthened to ac-tivate the vitality of socioeconomic development under green and sustainable development model,and promote high-quality coupling development of land ecological security and social economy.
