Abstract:

Based on the occurrence of resilience and the ability of cultivated land system to improve resilience, this study established a set of cultivated land system resilience evaluation index systems applicable to arid areas, with an aim to apply the resilience theory to the cultivated land system, evaluate the cultivated land system resilience and the spatiotemporal evolution characteristics of Xinjiang in the past 20 years, and propose policy suggestions on the sustainable use of cultivated land in Xinjiang from the perspective of resilience. Using grid as a scale, the resilience level of the cultivated land system in Xinjiang was measured using the comprehensive index method. Results showed that (1) The cultivated land area of Xinjiang increased during 2000-2020, and it was primarily distributed in areas with abundant water resources. (2) The resilience of the cultivated land system in Xinjiang increased slightly, but the overall level was still low, and the spatial heterogeneity was strong. In the past 20 years, the area with high value exhibited a trend of shifting to the south, primarily distributed in the valley delta area formed by the alluvial river. (3) In the past 20 years, the resilience and adaptability of the Xinjiang cultivated land system have increased, but the transformation ability has decreased. Regarding spatial distribution, the resilience and transformation ability of the cultivated land system in southern Xinjiang continuously improved, and the adaptive ability basically demonstrated a distribution pattern of “high in the north and low in the south.” Due to the different factors affecting the resilience of the cultivated land system in different regions, the cultivated land-use system was divided into five zones according to the resilience of the cultivated land system in 2020, and the specific optimization plan was proposed to improve the corresponding ability.
