Temporal and Spatial Evolution Characteristics of Landscape Pattern and Ecological Vulnerability in Yongtaiwen Coastal Zone
[Objective] An analysis of the land-use landscape pattern and a evolution characteristics of the ecological vulnerability were carried out for the coastal zones in the cities of Ningbo
Taizhou
and Wenzhou in the Zhejiang Province. This was aimed at promoting the sustainable development of the coastal zone and for providing a theoretical support for ecological construction and restoration.[Methods] Based on the land use data of the 1995-2015 phase Ⅲ of the Yongtaiwen coastal zone
the "pressure-sensitivity-resilience" evaluation model was used to evaluate the landscape type vulnerability and the ecological vulnerability of the study area.[Results] ① The change in the landscape pattern was as follows:The area of the cultivated land decreased the most
which was followed by tidal flats and woodland. Further
the area of construction land increased the most
and the amount of patches of cultivated and forest lands were observed to increase
showing a fragmentation trend. ② The areas with high ecological vulnerability were concentrated in Yuyao
Cixi City
and the Luqiao District of Taizhou Bay located on the south bank of Hangzhou Bay. In the past 20 years
the high vulnerability regions of the observed area had increased
and the overall ecological vulnerability had also intensified. ③ The regional ecological vulnerability was significantly and positively correlated with the disturbance index and the fragmentation degree; further
it was completely associated with the landscape vulnerability index.[Conclusion] Various landscape types in the Yongtaiwen coastal region have significantly changed and the ecological vulnerability has been observed to increase.
