Abstract:

The dike-pond system (DPS) has been recognized as a China Nationally Important Agricultural Heritage Systems site. Its macro pattern changes have been widely concerned, but the micro village level research has not been paid enough attention. This study constructed an analytical framework for the qualitative analysis of change of the DPS. Taking Xiqiao, Nanjin, Qingtian, and Shiban Villages in Foshan City as examples, field research and semistructured interviews were used to analyze the process, characteristics, and mechanism of change of the DPS. The results show that the DPS has changed from the original combination of planting and breeding to a high density pond system. However, the DPS was closely combined with the living space of the nearby village settlements, forming ecological landscape pond, vegetable dike-fish pond, and so on. Under the background of urbanization and industrialization, the operation and management of rural collective economic organizations and farmers that prioritize economic benefits is the internal driver of the DPS change. Changing the operation mode of the DPS, giving full play to the comprehensive benefits of the system, reasonably managing the interface between DPS and urban-rural space, and combining with the conservation of agricultural and cultural heritage and rural culture of DPS are crucial for realizing the ecological restoration of the DPS in the Pearl River Delta. This study can provide some theoretical basis for the the sustainable development of agriculture and territorial spatial planning of the Pearl River Delta.
