| 摘要: |
| 由于湿地生态系统的重要性、脆弱性和复杂性，湿地生态系统的保护与修复是当今世界的热点与难点问题之一。本研究选取天津滨海新区的3处湿地生态系统作为参考场地，1处湿地生态系统作为验证场地，通过量化4处场地不同类型栖息地的7个环境因素，综合鸟类对各类型栖息地的使用情况，并采用逐步回归分析，结果表明植被覆盖率、植物水平斑块丰富度及人为干扰程度与鸟类物种丰富度呈显著相关，并建立模型1；植物香农－威纳指数、植物水平斑块丰富度及人为干扰程度与鸟类共位群丰富度呈显著相关关系，并建立模型2。最后，利用验证场地的数据进行模型验证，得出所建立的模型能够较为准确地对栖息地内的鸟类丰富度进行预测。该研究构架了1种利用栖息地类型预测场地鸟类丰富度的方法，以期供相关研究或实际规划设计工作参考。 |

| Abstract: |
| Wetland ecosystem restoration and protection has been one of the hotspots and difficulties in the world with its high values, complexity and vulnerability. In this research, 3 wetland ecosystem sites were chosen as the reference ecosystem, and 1 site was chosen as the validation site, all of which are located in Tianjin Binhai New Area. In this research, 7 environmental factors were selected chosen from 4 sites with different types of habitats. Synthesizing bird use for various habitats, the outcomes of stepwise regression analyses showed that vegetation coverage rate, Vegetation horizontal patchiness and human disturbance had important correlation with bird species richness, model 1 was achieved, while Shannon-Wiener index, vegetation horizontal patchiness and human disturbance had important correlation with bird guild richness, accordingly, model 2 was also achieved. Then model verification was conducted using data from the validation site. The concise and effective method in this paper could be used in predicting the species richness and guild richness in a particular habitat, which are also expected to be an useful reference for relevant research, practical planning and design works. |
