Study On The Bird Community Of Wet And Green Land In Weifang

This paper studies the influence of the urban birds communities in the city's function and structure type of greenbelt, and birds on the adaptability of the urban environment. To discuss the relation of greenbelt, wetland environment and the bird community in Weifang urban.Weifang city functions in the types of environmental transport, residential areas, schools parks, scenic areas, business and industrial districts in six types of birds green resources survey results show Six types of birds green corporate structure and distribution, nest-choice situation exist a clear difference .Related to the analysis showed that due to human activities high natural scenery, the campus area, nesting, feeding, the bird species, the number of large, commercial areas, frequent traffic areas, and the number of bird species have very few. Selecting nest has two factors, First is nest tree height, diameter nest tree, another factor is high from the nest, Ecological and environmental changes on bird populations of both change and its impact on distribution. Pest and diversity of birds that were negatively correlated, the change of urban ecological environment have obviously affected on bird populations and distribution of the number of changes.Because of the special of ecosystem environment, the creature of marsh has the diverse character. Wetlands are a lot of endangered waterfowl habitats. Weifang city artificial wetlands for birds with a wide range of habitats, species of birds, the total number of birds, species diversity and endemism is higher than the surrounding area, is rich in wetlands bird species diversity More wetland birds nesting in woodland breeding, wetland birds and also an increase of woodland birds species diversity. The type and structure of city greenbelt and marsh play an important role in the city ecosystem system structure function (Clean air lower noise and"Hot island effect"), but else it distributes important influence in the structure of birds'community and ecosystem distribution.Anyway Distributing of birds and environment type are closely related, therefore, the variety of birds'community can be a kind of index sign of environment variety and reflected environment structure of feat degree, and the birds would adapt to the city to bring into play an action in the ecological equilibrium of city.This research make four suggestion on Weifang Urban Construction: (1) the size of the functions of cities and configuration to be reasonable, 2) to grow tall canopy trees as many as possible ,reducing the destruction of existing vegetation,(3) Should try to increase the diversity of vegetation,(4) Should try to build some more Wetland Park.
