| 摘 要： | 应用加权平均法和无度量多维标定(NMS)法，检测到影响太子河流域大型底栖动物空间分布最重要的栖境因子依次为底质、流速和水深. 对太子河流域大型底栖动物主要优势类群的栖境适宜度进行研究，结果表明:不同物种对生境表现出明显的趋异性，多数物种喜栖息在粗糙卵石底质的生境; 大型底栖动物的流速偏好性与其摄食方式、生活型和形体结构相关，对水深的偏好性差异较小. 对该流域主要优势种热水四节蜉(Baetis thermicus)的栖境适宜性研究表明，热水四节蜉偏好小卵石底质，最适流速为0.4 m/s，最适水深为0.2 m. 栖境适宜度指数的预测模型显示，热水四节蜉个体数在多数采样点的实测值小于预测值，表明除栖境指标外，其他的环境要素亦对该种的分布有重要影响.

| Abstract: | We used the weight averaging(WA) and nonmetric multidimensional scaling(NMS) methods to rank the most important habitat variables(i.e.substrate,velocity and water depth) influencing the spatial distribution of macroinvertebrates in the Taizi River basin in northeastern China.The habitat suitability results for the most abundant monoid of macroinvertebrates in the Taizi River basin showed that all of the species found in this study showed different habitat preferences.Most species preferred to live in habita... |
