环渤海海岸带水鸟栖息地适宜性评价及影响因素
Habitat suitability evaluation and influencing factors of waterbirds in coastal zone around Bohai Sea
摘要
Abstract
The coastal zone around Bohai Sea is rich in wetland resources,which are important habitat and resting place for many waterbirds on East Asian-Australian migration routes.Based on the data of waterbird geographical distribution and several environmental variables,the MaxEnt model was used to evaluate the suitability of waterbird habitats,and geographical detectors were used to quantitatively analyze the impacts of natural and social factors on the distribution of waterbirds.The results showed that:(1)The suitable distribution area of waterbirds in the coast-al zone around Bohai Sea was mainly concentrated in the boundary water of the coastline.The highly suitable area was mainly concentrated in the central part of the coastal zone around Bohai Sea.Tianjin occupied the largest highly suitable area with an area of 1706.1 km2,followed by Tangshan with an area of 1566.15 km2;(2)According to the results of the MaxEnt model,the primary factor driving the suitable habitat distribution of waterbirds in the coastal zone around Bohai Sea was vegetation type,followed by soil type and normalized difference vegetation index.The results of the geographical detectors showed that the main driving factor limiting the distribution of waterbirds was vegetation type.In addition,soil type,land use type,and normalized difference vegetation index were also impor-tant driving factors affecting the distribution of waterbirds,which were basically consistent with the results of the MaxEnt model.From the interaction of various factors,the interaction type of most factors was nonlinear enhance-ment,and the interaction type of a small number of factors was double-factor enhancement.Among them,the inter-action between nighttime lighting and vegetation type was the strongest,followed by that between vegetation type and normalized difference vegetation index.By identifying the key habitats of waterbirds in the coastal zone around Bohai Sea,our results provide a scientific basis for the protection,restoration,and management of waterbirds and their habitats in this region.关键词
