| 摘 要： | 为探讨产业化发展要求下的稻田种养空间落位及战略管理问题,该研究以江苏省为研究区,分别从自然适宜度和产业优势度两个维度,构建量化评估指标体系,综合评判稻田种养产业化开发的空间优先级,提出分区引导政策指引。基于水源、土壤、地形等自然因素的综合评级结果显示,江苏省高度适宜开发稻田种养的面积占全省水田总面积的13.8%,中度适宜开发面积占比57.0%;自然适宜度高值区主要分布在里下河地区并延伸至苏北灌溉总渠沿线,以及长江以南的东部沿江平原向南至太湖平原一带。基于劳动力、基础设施、软环境等层面的综合评级结果表明,苏北地区产业优势度高低互现,苏南地区产业优势度高值区主要分布在邻近上海、南京大都市的外围郊县区。通过对基于县域单元的两维度空间评级结果的耦合分析,划分为4类空间,按照重点发展、适度扶持、优化调整和控制开发等方向,分别提出稻田种养产业化开发策略。该研究可为提升稻田资源开发效率和稻田种养产业高质量发展提供决策参考。

| Abstract: | Abstract: A rice-aquatic coculture system is of great significance to explore the paddy field resources for the food supply security in the green development of agricultural industry. It is very necessary to identify the priority areas for the industrial decision-making on the overall planning and layout. Taking Jiangsu Province of China as the research area, this study aims to comprehensively evaluate the spatial priority level of industrialization development. A quantitative evaluation index system was also constructed from two dimensions of natural suitability and industrial dominance. Four indexes were selected for the natural suitability, including the water network density, water source abundance, soil sandiness, and terrain. The hydrology, terrain and soil data were applied using the grid unit in the paddy field. The priority rating of natural suitability at county level was assessed to transform from the comprehensive scores of the above indexes of natural space units to the score of county unit through scale conversion. Alternatively, the priority rating of industrial dominance was evaluated directly at the county level, where nine indexes were selected from three aspects of labor force, infrastructure and industrial soft environment, according to the production statistics data of key demonstration areas that issued by the agricultural administration department. The evaluation results showed that 13.8% of the total paddy field area in the study area was highly suitable for the rice-aquatic coculture systems, and 57.0% was the moderately suitable space; The high-score areas of natural suitability were mainly distributed in the Lixia River area and extended to the North Jiangsu irrigation canal in Northern Jiangsu, as well as the eastern Yangtze River plain south of the Yangtze River to the Tai-Lake Plain, indicating two concentrated distribution areas to the periphery. There was the high industrial dominance level around the hinterland of Lixia River plain in the north. By contrast, the high-score areas in the south were mainly distributed in the suburban counties adjacent to the metropolis of Shanghai and Nanjing. The development types were classified among all county-level administrative units, according to the combination characteristics of the priority rating of natural suitability and industrial dominance level. Four types with 16 squares at county level were then identified, corresponding to four development strategies: the key development, moderate support, optimized adjustment, and control development. Specifically, the key development areas were represented by the Lixia River plain area in the north and Tai-lake Plain water network area in the south. Differentiated industry can be orientated in the center of the industrial development of rice-aquatic production system, according to the dislocation competition strategy. The rest agricultural areas can turn the resource advantages into industrial ones, according to the development strategy of "one land, one aquatic product and one industry". The emphasis can be shifted from the quantity-based expansion to quality-based promotion in the areas around Hongze Lake, in order to strengthen the intensive and efficient utilization of paddy field resources for the industrial upgrading. These findings can provide references on the rice field resource for the high quality and efficiency in the rice-aquaculture industry. |
