摘要
2011年9月至2012年1月采用样线法、样点法及定时定点法相结合的方法,对渭南市城区秋冬季的鸟类资源和生境多样性、均匀度及相似性等群落特征进行了调查研究。调查结果表明,渭南市城区秋冬季共观测到野生鸟类38种,隶属于12目22科;优势种5种,常见种7种,其余均为稀有种。湿地生境中的物种多样性最高为2.257,市区最低为1.271;郊区与公园的相似性系数最高为0.867,市区与湿地生境的最低为0.320。建议渭南市政府加强市区内绿化力度,扩大市区内绿地面积,保持绿化面积的连续性;在城市绿化中丰富植被垂直结构,尽量保留其自然生态环境,增加鸟类物种多样性。
From Sep.2011 to Jau.2012,the birds resources and community characteristics such as habitat diversity,homogeneity and similarity in Weinan area were investigated by using line transect methods,point count methods and regularly targeted methods.The results showed that there were 38 species of birds belonging to 12 orders and 22 families in record.There were 7 predominant species,7 common species,and the others were rare species.The biodiversity of birds in wetlands was the highest(2.257) and in urban area was the lowest(1.271).The birds communities in suburb areas and parks had the most similarity(0.867),and the simarity coefficient between urban area and wetlands was the lowest(0.320).It was suggested that Weinan government should make efforts on greening in the urban area,expand the green area and maintain the continuity,try the best to rich vertical structure of vegetation,and preserve its natural habitat to increasing the diversity of birds.
