Abstract:Taking rural ecological belts situated in small watersheds as the research object, focusing on the three general characteristics of the natural diversity of its morphological structure, the composite diversity of its function, and the urgency of rainwater flood prevention and control, aiming at problems of the lack of systematic thinking, the homogenization of landscape, and the emphasis on the highlights rather than the whole in the construction of rural ecological belt in Guangzhou and Foshan, and taking into account the fact that rural ecological belts are mostly situated in small watersheds with no hydrological data, a rainfall inundation simulation model for different recurrence periods is proposed, which is based on indirect inference algorithm and digital elevation model. In addition, from the watershed system, a landscape planning strategy system under the multi-scale perspective is proposed, including a macro-watershed scale planning strategy with the main goal of tapping the potential resources of all parties in the countryside and promoting the development of land and water linkage, a mesoscale planning strategy with the main goal of creating diversified and unique recreational space, and the harmonious coexistence between humans and nature, and a microwatershed scale planning strategy with the primary goal of shaping resilient riverbanks and enhancing the natural attributes of rivers.
