围填海对盐城珍禽自然保护区越冬水鸟群落及空间分布的影响
Effects of reclamation on the community and spatial distribution of wintering waterbirds in Yancheng Nature Reserve
摘要
Abstract
Yancheng Nature Reserve is one of the important wintering sites for waterbirds in the world.With the increasing intensity of the reclamation activities in recent decades, the pattern of landscape has changed greatly.This change will certainly affect the community structure and spatial distribution of wintering waterbirds.We took the north buffer zone and the core area in Yancheng Nature Reserve as the study area.According to the landscape map of Yancheng Nature Reserve in 1975-2013, we divided the study area into nature area and reclaimed area.The species, population, diversity and spatial distribution of wintering waterbirds in nature area and reclaimed area during2009-2013 were analyzed.Our results showed that:1) Reclamation had a significant influence on the species composition of waterbirds, and the species and population of Anatidae in the reclaimed area are significantly higher than those in the nature areas.The change of land use type had a significant influence on the number of waterbirds species, and the influence of reclamation on the population and species of waterbirds in reed and salt works was significant.2) The change of land use types caused by reclamation had a significant influence on the Shannon-Wiener index of waterbirds, and the Shannon-Wiener index of fish ponds in reclaimed area was significantly higher than the nature area.3) The abundance of waterbirds in Suaeda glauca was largest in nature area and in Phragmites australias was largest in reclaimed area.The change of land use types caused by reclamation had a great influence on the habitat selection of storks, cranes, shorebirds and Anatidae.Habitat availability and human disturbance after reclamation determined the community structure and spatial distribution of waterbirds.关键词
