摘要
借鉴经济地理学研究方法,综合运用动态度和空间不平衡指数分析1989—2020年我国11个沿海省份蓝色农田面积的变化特征,运用重心分析模型和标准差椭圆法定量描绘我国蓝色农田空间格局演变的过程和规律,并构建固定效应模型分析蓝色农田空间演化的影响因素。结果表明:(1)我国海水养殖的不平衡指数持续上升,地区间差距逐渐增大,海水养殖的空间分布格局向不平衡方向演化;(2)海水养殖重心总体呈现由南(偏西)向北(偏东)的空间演变格局,移动范围由长三角地区迁移至环渤海地区,表明30年来沿黄渤海地区海水养殖业发展快于南方沿海地区;(3)蓝色农田空间格局的演变是海洋资源利用能力、海水养殖劳动力、冷链物流系统和居民消费能力等多种因素共同作用的结果。
Based on the research methods of economic geography,this paper quantitatively describes the change characteristics and spatial pattern evolution law of marine blue farmland in 11 coastal provinces of China from 1989 to 2020 by using dynamic degree,imbalance index and center of gravity analysis.Regression analysis model was used to analyze the influencing factors of spatial change of mariculture.The results show that:(1)The imbalance index of mariculture in China continues to rise,and the spatial pattern is more unbalanced.(2)The focus of mariculture has moved from south to north,indicating that the mariculture industry in the northern coastal areas has developed faster than that in the southern coastal areas in the past 30 years.(3)The evolution of the spatial pattern of blue farmland is the result of the joint action of many factors such as the utilization capacity of marine resources,the employment potential of mariculture,the cold chain logistics system and residents’consumption ability.
