The Study On The Birds' Diversity And The Research On Estimation Of Urban Ecological Environment In Linyi City

With modern industrial development and the size of cities expanding, from which derived the increasingly serious problem of environmental pollution. Urban Habitat environment is an important part of the environment that their growing importance highlighted. Authoritative international agencies forecast that in 2006 half the world's population or 32 million people will become urban residents. The construction of a harmonious living environment of human society is a sign of civilization, people and animals are want peaceful living environment.In January 2006 - December 2006, the author of Linyi in Shandong Province had selected seven different urban ecological environment types of birds in the study. while selecting five birds habitat parameter analysis to determine the impact of urban bird community's main environmental factor and urbanization made composite index as a measure of urbanization indicators of the ecological environment. Birds of community structure parameters evaluated different types of ecological environment diversity of birds, discuss the relation between birds diversity and habitat of birds and the feasibility of birds used as the city's ecological environment monitoring indicators. The research findings show: industrial area and transport area covering the bird community in the most similarity, the park plaza area and the city swamp area similar to the birds. The landscape level and interference factors (such as the distance to the city center, noise, human interference and construction indicators) on the distribution of birds, density, diversity and richness of different degrees of impact. Bird's density, diversity, richness decline with a higher level of cities urbanization. Analysis showed that bird diversity, community composition, distribution relation to quality of the environment, environmental quality decides bird diversity, community structure and ecological distribution. Therefore, the birds may reflect the city's ecological environment. Sparrow, Pica pica, Dendrocopos major, Pycnonotus sinensis, Upupa epops seems to be five species of birds in the urban environment as instructions species. The bird community diversity index, rich index, distribution coefficient, important values, community and other community's similar structural parameters can be used as the city's ecological environment monitoring indicators.
