摘要/Abstract

摘要：

伊犁河谷是维护新疆土地生态安全的重要生态保障区，其土地利用与土地生态安全相协调对区域可持续发展有重要意义。以2005—2020年土地利用数据为基础，采用综合指数模型、改进的耦合协调度模型和灰色关联度模型等方法对伊犁河谷2005—2020年土地利用隐性形态、土地生态安全时空特征以及两者协调特征进行研究。结果表明：（1） 2005—2020年伊犁河谷各县市土地利用隐性形态指数总体上缓慢提升，大体呈现以伊宁市为中心，向四周辐射降低的发展态势。（2） 2005—2020年伊犁河谷土地生态安全水平表现为波动增长趋势，并与土地利用隐性形态变化密切相关。（3） 2005—2020年伊犁河谷土地利用隐性形态与土地生态安全为高耦合关系，中心城市协调性高于边缘城市。（4）伊犁河谷土地利用隐性形态与土地生态安全协调发展程度主要受土地产出效益、土地开发强度、土地产权变化和生态环境的影响。

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.
