Study on ecological security pattern and driving force of urban agglomeration around Poyang Lake
Exploring the spatiotemporal pattern changes and driving forces of ecological security in urban agglomerations can provide a new perspective for local sustainable development and scientific basis for regional ecological civilization construction.This paper took the urban agglomeration around Poyang Lake as the research area,and used the Entropy Method and Grey Correlation Method to analyze the spatial and temporal distribution pattern and driving force of ecological security pattern in the research area in 2010,2013,2016 and 2019.The results showed that:(1)The ecological security pattern of the urban agglomeration around Poyang Lake was relatively stable from 2010 to 2019.The ecological security index was the highest in 2013 and the lowest in 2016.(2)Spatially,the growth poles dominated by Jiujiang and Yichun had obvious changes in the regional ecological security pattern of the urban agglomeration,and other cities were relatively stable.(3)The urban sewage treatment rate,the proportion of employees in the tertiary industry,the comprehensive utilization rate of industrial waste and the harmless treatment rate of life were the main driving force of ecological security in the urban agglomeration around Poyang Lake.Based on the above research,this paper puts forward some countermeasures and suggestions,such as adhering to the priority of ecological protection,planning ecological construction according to local conditions,adjusting planting and industrial structure and improving public awareness of ecological protection,ensuring the formation of a healthy and stable overall pattern of ecological security.
