- Abstract
【Objective】 To study the spatio-temporal pattern change of cotton production in Xinjiang, analyze the characteristics of spatio-temporal change of cotton production and the important causes of its influencing factors. 【Methods】 Based on the panel data of cotton production in Xinjiang from 1991 to 2020, this paper selected cotton regions in Xinjiang as the research object, took Xinjiang regions and major cotton producing counties and cities as the basic research unit, combined time series and space, comprehensively used statistical tools to analyze the cotton planting area, total output and unit output, and analyzed the space-time and regional characteristics of cotton production in Xinjiang, as well as the impact of various factors on cotton production in Xinjiang. 【Results】 The results showed that: (1) The annual changes of cotton planting area and total yield in Xinjiang since 1990 were similar, showing two stages: the period of increasing in fluctuation (1993-2010) and the period of leaping growth (2010-2020). During this period, the cotton areas in northern and southern Xinjiang continued to increase while the cotton areas in eastern Xinjiang decreased, showing a trend of "shrinking in the east, expanding in the south, and increasing in the north" in space. (2) In recent 30 years, the unit cotton yield in Xinjiang has increased significantly, from 0.81 × 103 kg/hm2 increased to 1.85 × 103 kg/hm2, an increase of nearly 1.28 times over the same period, with an average annual increase of 34.66 kg/hm2, showing a rapid growth rate, which is the main contributing factor to promote the sustainable growth of cotton output. (3) The change of total cotton output in Xinjiang is generally dominated by the contribution of area, followed by the unit area, and the interaction is the lowest. The dominant production area of cotton in Xinjiang is South Xinjiang. 【Conclusion】 Over the past 30 years, the cotton planting area in Xinjiang has continued to increase, the production concentration has continued to increase, the dominant production areas have tended to stabilize, and the unit yield has gradually increased; The cotton production layout shows that the cotton production center has shifted from Kashgar to Aksu.
