The conservation of wildlife habitats in the Beijing surrounding areas based on the EES system
Harmonious coexistence between man and nature is the essential requirement of Chinese modernization,and only through the coordinated development of the ecological-economic-social(EES)systems can a high-quality wildlife habitat,conducive to the harmonious development between humans and nature,be built.Based on the data from various districts around Beijing from 2009 to 2017,we select indicators from the EES system perspective and adopts the objec-tive-AHP method(Objective Analytic Hierarchy Process)to assign weights to each indicator.Based on the coefficient of variation coordination development model,we obtain the degree of coordinated development between the EES systems of wild animal habitats in each district.Finally,using Huairou District as an example,we explore the actual impact of the degree of coordinated development on the quality of wild animal habitats.The results show that using objective-AHP for weighting,the Spe-AHP judgment matrix with an AIC value of 505.707 6 is selected based on the principle of mini-mum AIC value.The maximum weight of the ecological system is 0.460 9,the weight of the social system is 0.281 7,and the weight of the economic system is 0.257 4.The coordination degree of each district is relatively high,except for the imbalance caused by the significant increase in the ecological system score,the others are in a coordinated state,but with low development,belonging to low development coordination.The degree of coordinated development of EES sys-tems shows a gradual increase over time.Among the six districts,Fangshan,Huairou,and Mentougou reached primary coordination in 2016 and 2017,with the quality of wild animal habitats being higher than in other districts.The coordina-tion between EES systems within habitats has a negative impact on the frequency of human-wildlife conflicts in the re-gion.
