Abstract

Abstract

In this paper, we evaluated the ecological restoration effect of transforming traditional paddy fields into ecological paddy fields in the rural wetlands of Chenhaiwei. To achieve this objective, we conducted field investigations and laboratory observations, from July 2018 to May 2019, of amphibians, benthic animals, and the water quality at a landscape lake, ecological paddy field, traditional paddy field, and residential ditch. The results showed that: ①Amphibian species decreased sequentially from the landscape lake, ecological paddy field, traditional paddy field, and residential ditch. There was not a significant difference in the number of amphibians observed between the landscape lake and the ecological paddy field, but the number of amphibians was significantly higher than those observed at the traditional paddy field and residential ditch. ②There were no significant differences in the types and numbers of benthic species among the four types of habitats in the wet season, but the ecological paddy field showed the least variety and quantity of benthic species in the dry season. ③The water quality indices of organic nitrogen and phosphorus from the ecological paddy field ranked in the middle among the four habitats, but chlorophyll-a concentration was the lowest. In general, ecological recovery improved to a certain extent after transforming the planting pattern of the rice field at Chenhaiwei, but the lack of scientific management is not conducive to species stability. We put forward suggestions for ecological management of paddy fields.
- species diversity,
- water quality,
- ecological rice paddy field,
- ecological restoration,
- ecological management
