In arid regions, climatic fluctuations significantly affect vegetation structure and function. Sun-induced chlorophyll fluorescence (SIF) can quantify certain physiological parameters of but has limitations in characterizing responses to climate change. This study analyzed the spatiotemporal differences response change across various ecological regions types from 2000 2020 Xinjiang. According China’s zoning, R1 (Altai Mountains-Western Junggar Mountains forest-steppe) R5 (Pamir-Kunlun Mountains-Altyn Tagh high-altitude desert grasslands) represent two extremes, while R2–R4 span forest-steppe ecosystems. We employed standardized precipitation evapotranspiration index (SPEI) at different timescales drought intensity frequency conjunction with global OCO-2 SIF products (GOSIF) normalized difference (NDVI) assess growth conditions. The results show that (1) between 2020, overall severity Xinjiang exhibited a slight deterioration, particularly northern (R1 R2), gradual transition short-term long-term R4 southern also displayed deterioration trend; however, remained relatively stable on SPEI24 timescale. (2) NDVI values an upward trend. However, densely vegetated areas (R1–R3), both declined, more pronounced decrease observed natural forests. (3) Vegetation showed stronger than Xinjiang, being sensitive structural (NDVI). R1, R2, R3 were primarily influenced by change, whereas affected Natural grasslands forests, lower cover are structurally impacted. provides important scientific basis for management adaptation emphasizing need differentiated strategies support sustainable development.

The Ili River Transboundary Basin is an important area within the Belt and Road Initiative, its ecological security impacts China–Kazakhstan diplomatic relations building of Initiative. Using copula method, this study quantifies vulnerability vegetation to drought in based on Normalized Difference Vegetation Index (NDVI) Standardized Precipitation Evapotranspiration (SPEI). highest June, with proportion highly vulnerable areas reaching 63.29% under extreme conditions. As severity increases, probability loss rises, being affected most June. From May drought-prone are mainly located Almaty Oblast East Kazakhstan. July September, found Valley southeastern Oblast. Rainfed croplands susceptible drought, while, for irrigated croplands, higher enhances mitigating effect irrigation measures. by semi-arid regions, particularly summer. These findings offer valuable scientific support management sustainable development region.

Xinjiang is located in an inland arid area, and it faces significant challenges water resource supply demand, with a fragile ecological environment. Exploring the internal relationship between time–space distribution of agricultural water–soil matching evolution ecosystem service value (ESV) Tailan River Irrigation District from 2000 to 2020, this study provides theoretical guidance for balance resources healthy sustainable development environment irrigation district. By integrating coefficient equivalent factor method, spatiotemporal ESV under change land use (LU) district are analyzed. Based on Pearson correlation, trade-off synergy two explored. The results show that following occurred past 20 years: (1) Grassland dryland categories biggest transfer-out transfer-in areas District, conversion mostly Jiamu Town Guleawati Township. (2) area reclamation rate increased gradually, among which highest was 85.93% Kezile lowest 76.37% average Gini 0.118, absolutely fair. (3) has consumption, but always fluctuates best worst. consumption Communist Youth League lowest, remained many years. (4) showed overall increasing trend, CNY 243 million 678 2020; addition, soil conservation, hydrological regulation, grassland, contributed most each period. (5) There services while there synergistic services.
