| 中文摘要: |
| 为探明滇西高原城市生态系统中鸟类栖息地质量特征,以大理市建成区为研究对象,构建包含土地利用、距水源距离、人为干扰强度等因子的评价体系,采用层次分析法确定指标权重,结合ArcGIS空间分析技术开展栖息地适宜性分级,并通过实地鸟类分布调查监测数据进行验证。研究结果显示,研究区可划分为面积占比分别为23.56%、46.82%和29.67%的适宜区(适宜性指数
2.53~3.44)、较适宜区(适宜性指数1.89~2.35)和不适宜区(适宜性指数<1.89)。适宜区主要分布于城市边缘地及洱海河道周边的自然绿地斑块,该区域具备充足的食物来源和隐蔽场所;不适宜区则集中在交通密集的高强度开发区,呈现显著的硬质地表特征与生物廊道断裂现象。 |

| In order to ascertain the quality characteristics of bird habitats in the urban ecosystem of the western Yunnan plateau, the built-up area of Dali City was taken as the research object. An evaluation system including factors such as land use, distance from water sources, and intensity of human disturbance was constructed. The analytic hierarchy process (AHP) was used to determine the weights of the indicators. The ArcGIS spatial analysis technology was combined to carry out the classification of habitat suitability, and the field survey and monitoring data of bird distribution were used for verification. The results showed that the study area could be divided into suitable areas (suitability index being 2.53-3.44) accounting for 23.56% of the total area, relatively suitable areas (suitability index being 1.89-2.35) accounting for 46.82%, and unsuitable areas (suitability index being<1.89) accounting for 29.67%. The suitable areas were mainly distributed in the natural green space patches at the urban margins and around the rivers of Erhai Lake, characterized by sufficient food sources and hidden shelter. The unsuitable
areas were concentrated in the high-intensity development zones with dense traffic, showing significant characteristics of hard ground surfaces and the fragmentation of biological corridors. |
