英文摘要Ponds are an important ecosystem in rural landscapes. They play an important role in water retention, aquatic products supply and biodiversity conservation. By using a questionnaire-based survey of rural households in a small watershed in the Three Gorges Reservoir area, we analyzed the distribution of ponds, their size and current status. The Integrated Valuation of Environmental Services and Tradeoffs (InVEST) model was used to evaluate the regulation, provision and culture services of the ponds. We found that pond density was high throughout hilly areas. About 20 ponds were within an area of 1 km(2). They were mainly distributed in the middle and lower parts of the basin. The presence of such a large number of ponds was considered remarkable. Water retention was the primary ecosystem service. On average, each pond contained about 4500 mm depth of water, which was 10 times that of the surrounding forest. However, with the transformation of agriculture in mountainous areas, the irrigation and domestic water services provided by ponds have declined. In recent years, ponds have been used predominantly for fish farming and leisure services. Aquaculture and multi-function ponds accounted for 54.55% and 27.7% of the surveyed ponds, respectively. Multi-function ponds consumed more water, but fish farming ponds were the most economically valuable. Due to weak environmental management and the decreasing economic value of ponds, it is necessary to conduct ecological management of ponds in accordance with societal changes in mountainous areas and to promote the protection and use of ponds.
