湖南省水稻产量时空特征及其影响因素分析
Spatiotemporal characteristics and driving mechanisms of rice production in Hunan Province
摘要
Abstract
[Purpose]In 2022,Hunan Province had the largest rice cultivation area and the second-highest rice production among all the provinces producing rice in China.It is critical to maintain stable rice output in Hunan Province to ensure national food security.[Method]This study analyzed the spatiotemporal patterns and influencing factors of rice production in Hunan Province from 2011 to 2022 using global spatial autocorrelation,hotspot analysis,and the Geodetector Model.[Result](1)From 2011 to 2022,both the total rice production and planting area in Hunan Province exhibited a trend of first increasing and then decreasing,with three distinct stages.(2)Rice production showed significant spatial clustering,characterized by a pattern of hot north and cold west.High-production areas were consistently concentrated in the Dongting Lake Plain in the north,whereas low-production areas were mainly in the mountainous western regions.(3)Multiple factors influenced rice production,most of which exhibited interactive enhancement effects.Cultivation area was the primary determinant of spatial heterogeneity,and farmland area,effective irrigation area,and rural population also played crucial roles.[Conclusion]Future research and policy efforts should consider the interplay of multiple factors,optimize spatial production patterns,and enhance both yield and production stability.关键词
