摘要
近年来,赤水河鱼类资源经历了受损、保护、恢复的过程.目前研究与实践集中于赤水河云南段,而对威信境内鱼类多样性研究未见报道.因此,结合历史相关资料及近年调查数据,研究了赤水河威信段鱼类多样性动态特征.结果表明,赤水河威信段鱼类有 5 目 10 科 46 属 51 种,其干支流鱼类多样性相似度高,不同空间尺度鱼类优势种组成有所差异,且近年鱼类物种恢复成效明显,其中干流鱼类2023 年物种数是2019 年的2.72 倍.
Abstract
In recent years,the fish resources of Chishui River have experienced the process of damage,protection and recovery.Most of the recent research and practice focus on Chishui River of Yunnan Province,but there is no report on the research of the fish biodiversity in Weixin County.Combined with historical data and recent survey data(2021.11-2023.10),we examined the dynamic characteristics of fish diversity in the Weixin Section of Chishui River.The results show that there are 5 orders,10 families,46 genera and 51 species distributed in Weixin section of Chishui River Basin.Its main stream and its tributaries have a high similarity in fish diversity,the composition of dominant species varies at different spatial scales,the marked achievements were scored in the restored fish species in the study area in recent years and the number of species in 2023 was 2.72 times that in 2019.
