21世纪以来苏南乡村工业用地演变特征研究——以江阴市为例

苏南地区乡村工业用地的演化过程是剖析区域乡村转型发展的核心内容。该文聚焦于苏南地区经济发达且乡村工业发达的江阴市,研究新世纪以来乡村工业用地的时空分布及其演化特征。结果表明:(1)2000～2016年,江阴市乡村工业用地面积大幅度增加,净增加2 543.28 hm~2;全市乡村工业用地分布特征集聚程度不断增加且地域差异显著;主要交通干道对乡村工业用地的布局引导作用逐渐加强,河流与乡镇驻地对乡村工业用地布局的指向性在下降。(2)乡村工业用地扩张强度在乡镇尺度上表现为北高南低,2000～2016年,各乡镇乡村工业用地均出现了不同程度的扩张,年均扩张指数在0.46%～1.12%之间,扩张最强的乡镇(璜土镇)年均扩张指数达到1.12%。(3)2000～2016年,乡村工业用地扩张以蔓延式为主,收缩式、填充式为辅,同时伴随着部分飞地式扩张。乡村工业用地扩张强度会影响扩张模式的分布,蔓延式、填充式扩张面积随着扩张强度的减弱而增加,以扩张强度D级为节点,飞地式扩张面积呈现先减少后增加的趋势。

Evolution Characteristics of Rural Industrial Land in Southern Jiangsu Since the New Millennium: A Case of Jiangyin City

The evolution process of rural industrial land in southern Jiangsu is the core content of regional rural transformation and development. We detect the spatio-temporal distribution characteristics of rural industrial land since the new millennium. The results show that: (1) From 2000 to 2016, the area of rural industrial land in Jiangyin City increased significantly, with a net increase of 2 543.28 hm2; The concentration of rural industrial land distribution characteristics increased continuously and the regional differences were significant; the main traffic road has gradually strengthened the layout of rural industries, and the directivity of rivers and townships to the layout of rural industrial land declined. (2) The intensity of rural industrial land expansion was high in the north; the rural industrial land in each township experienced different expansion degrees from 2000 to 2016, with an annual expansion index between 0.46% and 1.12%. (3) The expansion mode of rural industrial land was mainly contagious mode, supplemented by shrinkage and filling mode, accompanied by partly enclave mode. The intensity of rural industrial land expansion affected the expansion mode. Excessive expansion intensity inhibited the spread of rural industrial land. The spread and filled expansion area of rural increased industrial land with the weakening intensity.
