Analysis of the Avian Biodiversity in Qingliang Mountain Area in spring
Abstract
The Qingliang mountain area located in the downtown of Nanjing, there were plenty of botany species in Qingliang Mountain Area, such as forest, bamboos and grasslands, the environment was good habitat to avians. In this paper, avian resource of Qingliang mountain area was studied, 11 species was watched which belonging to 2 Orders and 7 Families. 2 summer breeding birds and 9 resident birds were recorded, 4 species were oriental realm birds, 2 species were palaearctic realm birds. The Shannon-Wiener Index was 1.6869, The Pielou Index was 0.3055, and The G-F Index was 0.2261. The feeding condition and safety condition affects the biodiversity of avian of Qingliang mountain area.

Introduction
Zhang Xiulei (2006) investigated the bird composition and population number of Mamize Nature Reserve in Sichuan, and recorded a total of 105 species, 7 orders, 23 families, and 1948 of birds, including 6 species of the national protected birds, 7 species of unique birds in China [1]. Birds’ areas are mainly composed of oriental components. The results of the analysis of varieties of the birds showed that the similarity index of bird community was the highest among plantations and shrub grassland habitats, and the similarity of bird community between shrub grassland and virgin forest was the lowest. The diversity index of secondary forest bird diversity was the highest, the lowest in the shrub grassland. And the number of the birds in the original forest was the biggest. The species had the highest density in the middle layer of the forest.
Xu Xiaojun (2006) conducted a census of bird resources in Shanghai World Expo Park and surrounding areas, and studied the correlation of bird quantity, species and environmental factors. The results showed that there were 67 species, 23 families, 7 orders of birds in the region, with a community diversity index of 3.46 [2]. The community structure and distribution characteristics of bird community were analyzed by probabilistic statistical method. The bird community index and the eight environmental indicators were analyzed. The results showed that the number, quantity and diversity index of the bird were significantly correlated with the area of the park, and water area, the shape index and the habitat species. The diversity and uniformity index of birds were significantly correlated with the total number of species. The number of birds was related to the location conditions in the environment.
Wu Yi (2007) investigated the diversity of birds in Yuexiu Park, Guangzhou, and recorded 43 species of birds, belonging to 8 orders and 20 families, of which 27 species of birds, two summer migratory birds, eight winter migratory birds, and 6 species of other breeding birds [3]. The characteristics of bird community in summer and winter habitats were compared and analyzed. And the diversity, density and dominance of birds in summer were higher than those in winter, while the diversity index and uniformity index were lower than those in winter. There are great differences in the species, quantity and diversity of birds in the six habitats of the lawns of Nanxiu Lake, the Jinyin Playground, Bamboo Forest, Nanxiu Grove, Nanxiu Lake and Central City. The diversity of birds is the highest. According to the diversity of birds in different environments of the park put forward the protection measures.
Qingliang Mountain, also known as Stone Mountain in the past, is squatting in the west corner of Nanjing City, located in the western of the Guangzhou Road, Nanjing. The height of Qingliang Mountain is more than 100 meters, a radius of about 4 km, has been built as Qingliang Mountain Park. The trees in the garden are lush, the terrain are steep. Qingliang Mountain Park is located in the downtown area of Nanjing, the surrounding residents gathered, shops everywhere, from 2006 onwards, Qingliang Mountain Park free to the public, as a city of Green Island, gets more and more attention from the public, this article started from the Qingliang Mountain area Bird diversity, trying to analyze the composition of the birds to reflect the urbanization process on the impact of urban birds and the evaluation of the environment.
Conclusion
5.1 Relationship between species and quantity and season On the whole, there are few types of birds in the spring of Qingliang Mountain area, which are not high in number, low in diversity, and low in uniformity and obvious in dominant species. This may be due to the beginning of the snowstorm, causing a large number of birds died, while the disaster also affected the migration and reproduction of birds. In February 2008, the Naval Air Force Nantong Airport Bird Survey was conducted to find the phenomenon of summer breeding of summer black birds in winter. This phenomenon can be used as evidence of a low number of bird species in Qingliang Mountain area. 5.2 Relationship between species and quantity and human activity The distribution of birds and human activities have a great relationship between the activities of birds are generally human activities or less disturbed areas, Qingliang Mountain area of human interference is large, and because of the winter bird biological characteristics and Ecological habits, resulting in the habitat of the species is small and uneven distribution, the frequency of human activities and the distribution of birds inversely proportional to the density, in summary, the Qingliang Mountain area of birds in the place where the interference is very small, by the impact of human interference.
From the above points, it can be seen that the factors that affect the diversity of birds in the spring area of Qingliang Mountain are food, human disturbance, niche, climate, species ecological habit and biological characteristics, but the factors affecting spring bird diversity are Food and safe habitat. According to the observation and analysis, the diversity of birds in Qingliang Mountain area is not high in spring, and the number of dominant species is relatively simple. It is in line with the typical characteristics of birds in the landscape state of urban landscape. For the management of Qingliang Mountain area, the following suggestions: you can plant a variety of landscape gardens, so that birds can provide a variety of habitat, which attract more kinds of birds. Strengthen the scenic area of plant conservation management, we found in the investigation of a lot of damage to the vegetation of greening behavior, in order to make the city park green and green, for the broad masses of people to provide a harmonious environment, the need for management attention, but also need the general public with the active.
