摘  要：
产卵场是水生生物生存和繁衍的重要场所,在不同的生活史阶段,大麻哈鱼(Oncorhynchus keta)对产卵场环境因子的需求有所不同。本研究基于2017年秋季—2018年春季呼玛河下游大麻哈鱼繁殖期、孵化期及降河洄游期的水质、水文和水生生物调查数据,采用构建模糊隶属函数和层次分析法,对不同季节的产卵场环境指标进行标准化计算和权重赋值,建立大麻哈鱼产卵场评估模型,对不同季节的产卵场适宜性进行分析。结果表明:呼玛河下游水域水质、水文因素能较好地满足大麻哈鱼产卵场所需的环境要求;无论秋、冬或春季,对呼玛河下游大麻哈鱼产卵场适宜性影响最大的因子是水温、溶解氧和底质,其次是氨氮、p H值和水深等,影响最小的因子是电导率和浮游动物生物量等;呼玛河下游秋、冬、春三个季节的大麻哈鱼产卵场适宜性指数分别为0.839、0.652和0.743,该区域大麻哈鱼产卵场生态环境适宜性良好,秋季最佳,其次为春季,冬季略差。

摘  要：
Spawning ground is an important place for the survival and reproduction of aquatic organisms. At different stages of life history,Oncorhynchus keta has different requirements for environmental factors. Based on the data of water quality,hydrology and aquatic organism survey during the breeding,hatching and migrating period of salmon in the lower reaches of Huma River from autumn 2017 to spring 2018,we used the fuzzy membership function and analytic hierarchy process to standardize the calculation and weight assignment of the environmental indices of salmon spawning ground. We established the evaluation model of salmon spawning ground to compare the suitability across different seasons. The results of standardization showed that water quality and hydrological factors in the lower reaches of the Huma River could better meet the environmental requirements of salmon spawning grounds. Weight analysis results showed that water temperature,dissolved oxygen,and sediment were the most important factors affecting the suitability of salmon spawning grounds in the lower reaches of the Huma River,followed by ammonia,pH and water depth,in autumn,winter,and spring. The results of the evaluation model showed that the suitability index of salmon spawning grounds in autumn,winter and spring were 0.839,0.652 and 0. 743,respectively. Our results indicated that the eco-environment suitability of salmon spawning grounds in the study region was good,with the best in autumn,followed by spring,and worse in winter.
