Abstract:

The Ili River Valley, as a representative region of arid oases, serves as a crucial ecological safeguard area for maintaining the ecological security of land in Xinjiang. The coordination between land use and land ecological security holds significance for the sustainable development of the region. Based on remote sensing image data from 2005, 2010, 2015, and 2020, this study utilized comprehensive index models, and improved coupling coordination and gray relational degree models to investigate the spatio-temporal characteristics of the implicit forms of land use and the coupling coordination features with land ecological security in the Ili River Valley. The results indicate that: (1) The implicit forms of land use index exhibited a “w” shaped variation from 2005 to 2020, showing a gradual overall increase. It generally appeared to develop with Yining City as the center, radiating outwards with reduced intensity. (2) The comprehensive level of land ecological security showed a fluctuating growth trend from 2005 to 2020, closely correlated with changes in implicit forms of land use. (3) There was a high coupling relationship between the implicit forms of land use and land ecological security from 2005 to 2020. The level of coupling coordination gradually enhanced, with the central cities exhibiting higher coordination than the peripheral ones. (4) The coupling coordination between implicit forms of land use and land ecological security was mainly influenced by factors such as land output benefits, land development intensity, changes in land property rights, and ecological environment. It is imperative to comprehensively analyze the historical and future trends of implicit forms of land use and land ecological security, propose tailored strategies, and further enhance the level of land ecological security. This can accelerate the development of a green ecological economy and advance the construction of ecological civilization.
