Comprehensive Measures Of Eco-environmental Sustainability And Analysis Of Its Influence Factors In China

China's long-standing extensive economic development model is at the expense of the environment.With the rapid economic growth and the continuous consumption of resources and the increasing deterioration of the environment,it not only threatens the survival of mankind,but also hinders the sustainability of the social economy.development of.As the basic subsystem of the regional sustainable development system,the eco-environmental subsystem determines the speed with which China's sustainable development goals are achieved.It is of great significance for China to achieve sustainable development to grasp the current status of ecological and environmental sustainability of various provincial administrative regions in China,and to understand the regularity of ecological and environmental sustainability in time series and spatial evolution.Based on the Sustainable Development Goals(SDGs),this paper builds an evaluation index system for the sustainability of China's ecological environment,and adopts a variety of quantitative methods to carry out a two-dimensional synthesis of the ecological and environmental sustainability of China ' s 30 provincial administrative regions.Measure,analyze the temporal and spatial evolution of China's ecological and environmental sustainability,and finally explore the impact factors of ecological and environmental sustainability through quantitative methods,and conduct further comprehensive and systematic research on China's ecological and environmental sustainability.The conclusions are as follows:(1)From 2000 to 2018,China's ecological and environmental sustainability was generally not high.The average value of the sustainability evaluation index was 0.3529.There is room for further improvement of the ecological and environmental sustainability;at the regional level,the ecology of the three major regions of China's east,middle and west Environmental sustainability is not much different.Among them,the eco-environmental sustainability in the eastern region is the highest,followed by the central and western regions,showing eastern>central>western;at the provincial level,the ecological environmental sustainability gap between provinces shows a narrowing trend,and the overall The "low gap level" has evolved to a "small gap high level",showing a decreasing gradient from east to middle and west;from theperspective of pressure,state,and response subsystems,the values of the state and response system are showing an upward trend in fluctuations,pressure The value of the system shows a downward trend.(2)From a time series perspective,China's ecological and environmental sustainability showed an increasing trend year by year from 2000 to 2018,and the long-term or potential trends of the ecological and environmental sustainability in the eastern,central,and western regions all showed an increasing trend year by year;From the perspective of global correlation,the sustainability of China's ecological environment from 2000 to 2018 shows a significant positive correlation in spatial distribution,and the overall spatial agglomeration is constantly strengthening;from the perspective of local correlation,China's ecological environment from 2000 to 2018 is sustainable The continuous expansion of sexual hotspots and the shrinking of coldspots indicate that high-levels are increasing and low-levels are shrinking,and a stable distribution pattern is formed.Coldspots are distributed in the northwest for a long time and hotspots in the southeast for a long time.(3)Through regression analysis,the factors affecting the sustainability of China's ecological environment are explored,and it is concluded that the increase in per capita GDP and GDP growth rate has a significant role in promoting the sustainability of the ecological environment,indicating that the improvement of economic development level and the ecological environment The level of sustainability will also increase relatively;population density,urbanization rate,energy consumption per10,000 yuan of GDP,and the increase in the proportion of secondary industry to GDP have a significant inhibitory effect on the improvement of the sustainability of the ecological environment.
