Research on Habitat Restoration Strategy of Wading Birds Based on Habitat Suitability Index Model
Biodiversity is the basis for maintaining ecosystem balance.Taking urban wading bird habitat as the research object,Habitat Suitability Index(HSI)model was introduced for quantitative assessment of habitat quality.It provides scientific basis for biodiversity conservation,natural habitat restoration and human-bird relationship balance.Taking Xuanwu Lake area of Zijin Mountain in Nanjing as an example,the application process of HSI model in wading bird habitat restoration was discussed.The HSI model was constructed from three levels of foraging,nesting and human disturbance by combining subjective and objective methods.Habitat data were obtained through field measurement and literature collection to evaluate habitat suitability.The overall habitat suitability of the study area is higher.Habitat areas with high scores have shallow water depth,abundant aquatic plants,suitable nesting sites around,and low human activities.Habitat areas with poor scores are characterized by frequent human activities and heavy external disturbances.According to the results of habitat suitability evaluation of wading birds in the study area,habitat restoration strategies were proposed in three aspects:system design,microhabitat design,and recreation design.
