摘要
金盆山自然保护区位于赣州市信丰县东部,地处武夷山脉与南岭山脉之间的过渡区域。2015年7月对该保护区的鱼类资源开展初步调查,共记录鱼类3目6科13种,以鲤形目鲤科鱼类为主,占53.8%。其中侧条光唇鱼Acrossocheilus parallens、宽鳍鱲Zacco platypus和台湾白甲鱼Onychostoma barbatula为优势种,其体长分别以4~9cm、5~8cm和5~9cm为主。鱼类群落的Shannon-Wiener多样性指数、Margalef丰富度指数和Pielou均匀度指数分别为1.46、2.02和0.57,各采样点间有一定差异,总体随海拔升高而下降。ABC曲线分析显示：鱼类群落受到一定程度的干扰。
The fish resources were investigated in Jinpenshan Nature Reserve between the Wuyi Mountains and the Nanling Mountains, located in the eastern Xinfeng County, Ganzhou City, in July of 2015. A total of 379 fish samples were collected and classified into 13 species in 6 families, and 3 orders, with dominant family Cyprinidae, accounting for 53.85%（seven species） of the total species number of fish collected. The most abundant fish species was Acrossocheilus parallens with dominant standard length of 4 ~ 9cm, followed by Zacco platypus and Onychostoma barbatula with dominant standard length of 5 ~ 8 cm and 5 ~ 9 cm. The Shannon-Wiener diversity index was found to be 1.46, Margalef abundant index 2.02 and Pielou evenness index 0.57, these indices being decreased with elevated sea level. There was spatial variation in the fish community in the nature reserve in summer. Abundance biomass comparison curve indicated that the fish community in the nature reserve was affected by human activity moderately.
