21世纪以来苏北种植结构变化与成因分析
The change and cause of planting structure in Northern Jiangsu province since the 21st century
摘要
Abstract
The changes and causes of planting structure in Northern Jiangsu province since the 21st century were ana-lyzed by means of time series change analysis and comparative study.The results indicate that since the 21st century,the sown area of crops in Northern Jiangsu has been consistently increasing,primarily driven by a continuous expansion in grain crop cultivation.In contrast to Southern and Central Jiangsu,the sown area and proportion of grain crops in North-ern Jiangsu have shown an upward trajectory,with significant increases observed in wheat,rice,and corn cultivation while soybean and potato cultivation have decreased notably.The shift in non-food crop cultivation patterns in Northern Jiangsu aligns with those seen in Central Jiangsu but differs from Southern Jiangsu;melon,fruit,and vegetable crops have experienced one increase and two decreases while rape and cotton cultivation has significantly declined.As a result,the planting structure of Northern Jiangsu has evolved into a composition comprising grains as well as food crops alongside economic crops such as vegetables and fruits-transforming it into a new vegetable and grain production matrix in Jiangsu.Policy regulations have played a pivotal role by ensuring secure crop planting space,improving farmland infrastructure conditions,supporting scientific progress through technological advancements,along with implementing incentive meas-ures to enhance competitiveness across food production including vegetables and fruits.However considering the impera-tive need to embrace sustainable agricultural practices for increased food production while also increase farmers'income levels-the planting structure in Northern Jiangsu will experience pressure for further Policy adjustment.关键词
