摘  要:
为探寻张家界市大鲵生态繁育工程结构的关键因子与大鲵生态繁育的技术特点,实地调查10个大鲵生态繁育场,测量生态池的结构参数和主要水质指标,采用主成分分析方法,探讨生态繁育工程中影响大鲵亲本繁育的主要因子。结果表明:水深、繁育池底质、两岸坡度、植被类型、植被覆盖率与人为干扰是人工溪流结构参数的主要因子;洞穴面积、洞口宽与洞口高、水深与洞底组成均为洞穴结构参数的主要因子;浊度、总硬度、p H值和硫化物、溶解氧、总氮、总磷含量及化学耗氧量为水质指标主要因子。张家界市大鲵生态繁育选用亲本的规格较大,年龄为(8.4±3.6)龄,繁殖率为64.9±52.6,繁育工程中主要存在雌雄鉴别不清与孵化率低等问题。

摘  要:
In order to explore the key factors and technique affecting structure characteristic of ecological engineering for Chinese giant salamander breeding in Zhangjiajie city, ten ecological breeding farms were investigated in field, as well as the structural parameters of their ecological pool and water quality. Principal component analysis was used to pick out the main factors in the ecological engineering breeding. The results showed that water depth, substrate of breeding pool, bank gradient, vegetation type, coverage and human interference were the main structural parameters of artificial stream; Cave area, width and hight of cave entrance, depth of water and substrate composition were the main structural parameters of cave, and turbidity, total hardness, p H value, sulfide, dissolved oxygen, total nitrogen, total phosphor and chemical oxygen demand were the main factors of water quality index. The parent specifications of Chinese giant salamander were relatively large to an average age of 8.4±3.6, and the average reproductive rate was 64.9±52.6. The ambiguousness of sex discrimination and low hatching rate were the major problem in the ecological engineering breeding.
