摘　　要：为探究银川市中心城区不同滨水绿地的鸟类群落组成及丰富度、多度、多样性、均匀度和相似性指数的差异,于2020年8月—2021年7月采用样线法对银川市中心城区的16个典型滨水绿地中鸟类群落进行调查。结果表明:调查共记录到鸟类15目38科98种;近郊区滨水绿地的鸟类丰富度高于建成区相同滨水绿地;不同类型滨水绿地的鸟类丰富度具有显著差异,大面积块状滨水绿地类型的鸟类丰富度最高,带状滨水绿地类型最低;近郊区大面积块状滨水绿地类型、中等面积块状滨水绿地类型和建成区大面积块状滨水绿地类型的鸟类丰富度和多度较高且鸟类群落较相似;建成区中等面积块状滨水绿地和带状滨水绿地类型鸟类群落结构呈现单一化。研究推测环境干扰、用地面积和生境质量是影响滨水绿地鸟类群落结构差异的主要因素。To explore the differences of bird community in its composition,richness,populations,diversity,evenness,and similarity index among different waterfront green spaces in the city core of Yinchuan,the authors conduct a field survey on birds in the 16 typical waterfront green spaces in the city core from August 2020 to July 2021 using line-transect survey method.The results show that a total of 98 bird species in 15 orders of 38 families are recorded through the survey.The waterfront green spaces in the inner suburb have higher bird species richness than that of in the built-up area.Significant differences are found in bird species richness among different types of waterfront green spaces,and large-area waterfront green spaces have the highest bird species richness while waterfront green belts have the lowest.The bird species richness and abundance are higher in the large-and medium-areas waterfront green spaces in the inner suburb and the large-areas waterfront green space in the built-up area,in which bird communities are similar.The bird communities at medium-areas waterfront green spaces and waterfront green belts in the built-up area are simple in structure.It is inferred that environmental disturbance,land area,and habitat quality are the main factors affecting bird community structure in waterfront green spaces.
