The Research On The Compling Relationship Between Urbanization And Eco-environment Of Jinjiang

Urbanization is an inevitable trend of the human society developmental,on one hand,it brought us a highly-developed material civilization;on the other hand,it caused a series of ecological problems.Under the current new normal conditions of social and economic development,especially the "Maritime Silk Road in the 21st Century" and the "Silk Road Economic Belt",the study on the coupling and development of urbanization and ecological environment of Jinjiang is particularly important.Based on DMSP/OLS night-time remote sensing data and statistical data,this paper constructs the urbanization level measurement model,and uses the spatial autocorrelation analysis method to study the urbanization development characteristics of Jinjiang.Using the principal component analysis method to integrate green,wetness,dryness and heat,the coupling and harmonious development model was introduced to analyze the coupling and coordination of urbanization and eco-environment in Jinjiang.Some suggestions and measures were put forward for the research results.The results showed that the level of urbanization in Jinjiang increased from 1995 to 2015,and the growth rate slowed down.The urbanization level had obvious spatial agglomeration,and the level of spatial agglomeration was declining,the northeastern region(Especially the central region)in the tightening;1995-2015 Jinjiang ecological status showed an overall downward trend.The high-value areas were mainly distributed in the Purple Ridge Fruit Forest Farm in the north of Jinjiang,in the vicinity of Tiecheng Mountain Forest Farn in Chidian Town,and in Xibin Farm and Riverside Park in the northeastern part of the city,Of the low-value areas along the Century Boulevard were banded distribution,the other low-value areas are mostly small patchy scattered more scattered in the various administrative regions of the township,and a smaller range;1995-2013 Jinjiang,towns(streets)Coupling and harmonious development of urbanization and ecological environment improved in general,the average coupling degree increased from 0.4701 in 1995 to 0.7015 in 2013,an increase of 52.93%,the mean value of coupling coordination increased from 0.4587 to 0.7015,from the primary coordination stage The paper concludes that it is necessary to push forward the construction of ecological civilization,strictly control the disorderly expansion of construction land and speed up the adjustment of industrial structure.This paper will provide a basic evidence for eco-environmental construction and urbanization development in Jinjiang,and provide a new perspective for ecological monitoring in other coastal areas.
