栖息地适宜性指数模型，并通过野外实测和文献收集获取栖息

提出了系统设计、微生境设计和游憩设计3项针对性的栖息地

| Abstract: |
| 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. |
