摘要/Abstract

摘要： 在室内微生境模拟条件下，应用试验生态学方法，分别评估了岩原鲤幼鱼对底质、光照、水深3种生境因子的适宜性指数（HSI），建立了其栖息地适宜性模型，并初步估算了岩原鲤幼鱼的最小栖息面积.结果表明：岩原鲤幼鱼对底质、光照、水深3种生境因子的适宜栖息范围分别为砾石直径10~15 cm、光照强度0.2~1.8 lx、水深范围0~15 cm (离底距离)；其适宜性指数表达式分别为SI_S=1.7338e^-0.997x(R²=0.89，P＜0.01，SI_S为底质适宜性指数，x为砾石直径)、SI_L=3.0121e^-1.339x(R²=0.93，P＜0.01，SI_L为光照适宜性指数，x为光强)、SI_W=2.4055e^-1.245x(R²=0.97，P＜0.01，SI_W为水深适宜性指数，x为水深).算术平均法最适用于岩原鲤幼鱼的栖息地适宜性模型估计，最适模型为HSI=(SI_S+SI_L+SI_W)/3.共发现7组岩原鲤幼鱼建立并维持着相对稳定的栖息地范围，其栖息地面积范围为628~2015 cm²，平均值为1114 cm².

Abstract: Under the conditions of simulated micro-habitat in laboratory, and by using experimental ecological methods, this paper evaluated the suitability index (HSI) of young Procypris rabaudi for habitat factors (substrate, light intensity and water depth). The habitat suitability models of the young P. rabaudi were established, and the minimum habitat area of the young P. rabaudi was estimated. The young P. rabaudi preferred the habitats with the gravel diameter from 10 to 15 cm, light intensity from 0.2 to 1.8 lx, and water depth from 0 to 15 cm (distance from the bottom of the tank). The three suitability index models of the substrate, light intensity and water depth for the young P. rabaudi were SI_S=1.7338e^-0.997x(SI_S is the suitability index of substrate, and x is the gravel diameter; R²=0.89, P<0.01), SI_L=3.0121e^-1.339x(SI_L is the suitability index of light intensity, and x is the light intensity; R²=0.93,P<0.01), and SI_W=2.4055e^-1.245x(SI_W is the suitability index of water depth, and x is the water depth; R²=0.97, P<0.01), respectively. Arithmetic mean model HSI=(SI_S+SI_L+SI_W)/3 was most available for the estimation of the habitat suitability of young P. rabaudi. A total of seven groups of young P. rabaudi which established and maintained a relatively stable habitat area range were found. This habitat area ranged from 628 to 2015 cm², with an average of 1114 cm².
