| 摘要: |
| 以人口分布相对集中的区域杭州湾河口为例，通过遥感技术、野外调查和典型对应分析（CCA）排序分析的方法，对该区域的鸟类群落组成和结构进行研究.结果表明：1）土地利用与土地覆盖（LULC）影响鸟类群落的组成，鸟类的种类分别为农田31种、滩涂湿地30种、工业园区18种；鸟类的数量组成分别为滩涂湿地588只次、农田356只次、工业园区156只次.2）调查区共记录到保护鸟类5目6科6种80只次，其中2种被列为国家重点保护动物、二级保护动物名录，4种被列为浙江省重点保护陆生野生动物名录.3）CCA表明：人类活动的强度影响鸟类的组成和结构.4）生境的异质性、干扰程度与鸟类群落的组成密切相关，鸟类群落结构为适应生境变化而出现一定的梯度变化. |

| Abstract: |
| With the Hangzhou Bay where the population distribution is relatively concentrated as an example, using remote sensing technology, field investigation and canonical correspondence analysis(CCA) sequencing analysis, we studied the composition and structure of the bird community. The results show that:1)Land use and land cover(LULC) affected the composition of bird community. In the species composition of birds, 31, 30 and 18 species of birds were found infarmland, tidal flat wetland, and industrial park, respectively. In the population composition of birds, 588, 356 and 156 birds were found in beach wetland, farmland and industrial park, respectively. 2)A total of 80 birds of 6 species, 6 families, and 5 orders were recorded in the investigation area, among which 2 species were listed as the national second-class key protected animals, and 4 species were listed as the key protected terrestrial wild animals of Zhejiang Province. 3)CCA shows that the intensity of human activities affects the composition and structure of birds. 4)Habitat heterogeneity and disturbance degree are closely related to bird community composition, and bird community structure has a gradient change in order to adapt to habitat change. |
