Ecological Environment Assessment and Influencing Factors in Anhui Section of Huaihe River Basin Based on DPSIR Model
Based on the DPSIR model,the ecological security index of Anhui section of the Huaihe River Basin from 2012 to 2022 was calculated by entropy weight-TOPSIS method,the future eco-logical status was predicted by grey GM(1,1),and the obstacle degree model was introduced to i-dentify the key influencing factors.The results showed that:(a)The ecological security of Anhui section of the Huaihe River Basin showed an upward trend from 2012 to 2022,and the ecological security index was in the following order:Bengbu,Fuyang,Hefei,Suzhou,Chuzhou,Lu'an,Huainan,Bozhou and Huaibei.(b)There were regional disparities in the ecological security in-dex,and the southern Anhui area was generally higher than the northern Anhui area,and the future development level of the northern Anhui area needed to be improved.(c)The five key influen-cing factors are:fiscal expenditure on energy conservation and environmental protection,per capita water resources,economic density,per capita GDP and general public budget.
