深入理解淡水养殖水面结构转型是贯彻落实新发展理念和大食物观的必然要求,对促进全球可持续发展具有重要意义.然而,有关淡水养殖水面结构变化的研究还十分不足.论文在认识到淡水产品市场需求和河湖长制等水域管控政策对淡水养殖的影响基础上,综合运用Simpson多样性指数、地理要素重心模型和面板回归模型,从类型结构和空间结构两方面研究揭示江汉平原养殖水面的转型特征,着重探索市场诱致和政策管控共同作用下养殖水面结构转型的驱动机制.结果表明:①2001-2020年,江汉平原养殖水面从快速扩张转为扩张减缓,类型结构发生了"大水转小水、小水精养化、综合种养化主导"的转型,空间结构出现了"大水爬坡、小水向江"的转型趋势;②市场诱致性类型替代叠加政策强制性结构调整共同驱动了江汉平原养殖水面结构转型.其中,前者即以追求劳动生产力最大化为养殖目标的自下而上市场诱致性类型替代,后者即以河湖长制为代表的自上而下的水域管控政策实施导致的结构调整.此外,论文提出了加强江汉平原养殖水面结构转型调控的政策建议.研究结果有助于土地利用转型研究对象向养殖水面拓展,同时能够为从结构演化视角开展土地利用转型研究提供案例支撑.
Structural transition route of aquacultural water surfaces on the Jianghan Plain and mechanisms
An in-depth understanding of the transition of freshwater aquacultural water surfaces is significant for implementing the new development concept and macro view on food and for promoting global sustainable development.However,studies on the structural transition of aquacultural water surfaces and its driving mechanisms are still very limited.As socioeconomic development progresses,there are significant impacts of the growing market demand of freshwater products and water control policies such as the lake chief system on aquacultural water surfaces.Using the Simpson index method,center of gravity model of geographic factors,and panel regression models,we took the Jianghan Plain as an example to reveal the structural transition characteristics of aquacultural water surfaces from the perspectives of type structure and spatial structure by focusing on the mechanisms under the combined effects of market-induced changes and policy control.The results show that:1)From 2001 to 2020,the freshwater aquacultural water surfaces on the Jianghan Plain experienced a transition from rapid expansion to slow expansion;the type structure experienced a transition of"large water to small water,small water refinement,and comprehensive breeding dominance";the spatial structure experienced a transition of"large water climbing,small water towards the river".2)Market-induced type substitution mechanism,that is,the bottom-up market-induced substitution of aquacultural water surface types driven by the pursuit of labor productivity maximization,combined with the policy compulsory structural adjustment mechanism,that is,the top-down water control policy implementation such as the lake chief system,has driven the structural transition of aquacultural water surfaces on the Jianghan Plain.In addition,this article proposed policy recommendations to strengthen the regulation of structural transition of aquacultural water surfaces.This study is important for promoting the expansion of land use transition research to aquacultural water surfaces and deepen the analysis of structural evolution.
