Abstract
Taking Qingdao West Coast New Area as the study area, the risk index of landscape
ecosystem structure was constructed to evaluate the regional ecosystem structure
pattern from 1992 to 2017. And using the geographical weighted regression model
to analyze the spatial and temporal evolution relationship between landscape
structure and related construction factors in the West Coast New Area. The results
showed that: from 1992 to 2017, the urban construction land, vegetation and water
structure risks of landscape ecosystems in the West Coast New Area fluctuated in
different ranges, and the urban expansion and construction resulted in increased
risks of vegetation and water landscape structure, the stability of ecosystem
structure security pattern in the West Coast New Area has been decreasing. The
landscape structure has been affected by the urban construction behavior, which has
a significant correlation with the urban built-up areas in 1992, NDBI(normalized
difference build-up index), ports and railways. The areas affected by the sensitive
factors have expanded, showing a zonal distribution, and gradually spread to the
developed logistics ports in the east.
