摘要: 建立了基于模糊综合评价方法的鱼类栖息地模型, 并与水环境模型耦合。引入景观生态学的指标, 对鱼类栖息地适应性模型的结果进行分析, 从而进行鱼类生境质量评价。选取了漓江中游一复式河道, 以光倒刺鲃为研究对象, 建立了光倒刺鲃产卵期的鱼类栖息地适应性模型, 选取了斑块数、斑块凝聚度、连接度等景观生态学指标对模型的结果进行了栖息地质量评价。研究表明传统的、仅仅以WUA(加权可利用面积)作为栖息地质量评价指标的方法不能准确反映鱼类的生境质量。建立的评价方法更准确地反映了鱼类生境的状况, 可为鱼类栖息地保护提供支持。

Abstract: A fish habitat suitability model was developed using fuzzy comprehensive evaluation method by coupling water environment model. Indexes in landscape ecology were introduced into the model to evaluate the quality of fish habitat based on the output of HSI (Habitat Suitability Index) model. A compound channel in the middle reach of Lijiang River was selected for the case study on Spinibarbus hollandi. The HSI model for Spinibarbus hollandi in its spawning period was established. Evaluations of fish habitat based on the modelling results showed that WUA (Weighted Usable Area) cannot be the only index to precisely reflect habitat quality. Other Indexes such as the number and cohesiveness of patch and the degree of connectivity should also be included. The evaluation method in this research can be a helpful reference for fish habitat protection.

Key words: habitat suitability, indexes of landscape ecology, habitat quality
