Abstract:
With the resource spillover development of megacities, the suburban township ecosystem has been severely impacted, while the ecological environment has deteriorated, the township development has also been constrained. Township ecology is a part of regional and even national ecological pattern, and improving ecosystem resilience is of great significance for regional coordinated development and rural revitalization. In this paper, the PSR (Pressure-State-Response) model is used to build the evaluation index system of township ecological resilience from the dynamic perspective of township system's own state change and response after external interference, and the ecological resilience of 26 townships in Jizhou District of Tianjin is weighted by the combination of AHP and entropy weight method, and the ecological resilience in three dimensions of pressure, state and response was obtained, and the overall ecological resilience of townships in Jizhou District was determined. The results show that the ecological resilience level among the townships in Jizhou District is different that is high in the north and low in the south in the spatial dimension. In view of the problems reflected in the evaluation results, regulation and control should be taken from the three dimensions of pressure, state and response, so as to provide useful references for improving the ecological resilience of villages and towns.
