摘要
为了探究城镇化水平与生态系统服务价值的关系,利用综合指数法、价值当量法等方法测算2010、2015、2018年张承地区生态系统服务价值和城镇化水平,并运用空间自相关分析法、排序分析法、弹性系数等研究城镇化与生态系统服务价值的空间相关性特征、相关性强弱和协调关系。结果表明:(1)研究期间,张承地区生态系统服务价值呈现降低趋势,减少7.47×10^(8)元。(2)研究期间张承地区城镇化水平总体不高,城镇化综合指数的平均值由0.14上升至0.25。(3)县域协调关系最为显著的是极不协调发展,极不协调发展的县区占50%;尚义县处于协调发展状态;桥东区、桥西区等区域处于冲突状态,其余县区处于潜在威胁状态。(4)张承地区生态系统服务价值与城镇化水平之间存在空间负相关关系,不同县区的城镇化水平多度值位序与生态系统服务价值多度值排序存在显著差异。研究结果有利于进一步丰富城镇化与生态系统服务价值的相互作用理论。
In order to explore the relationship between urbanization level and ecosystem service value,this paper used the comprehensive index method and the value equivalent method to calculate the ecosystem service value and urbanization level in Zhang-Cheng area in the year of 2010,2015 and 2018,it also used spatial autocorrelation analysis method and ranking analysis method and elasticity coefficient to study the spatial correlation characteristics,correlation strength and coordination relationship between urbanization and ecosystem service value.The results showed that:(1)The ecosystem service value of Zhang-Cheng area decreased 7.47×10^(8) yuan during the study period.(2)During the study period,the urbanization level of Zhang-Cheng area was not high,and the average urbanization index increased from 0.14 to 0.25.(3)The most obvious coordination relations among counties were extremely uncoordinated development,with 50%of the counties and districts had extremely uncoordinated development;Shangyi County was in a state of coordinated development;and the eastern and western districts of the bridge were in a state of conflict,the rest of the counties were under threat.(4)There was a negative correlation between ecosystem service value and urbanization level in Zhang-Cheng area,and the negative correlation was strong.There were significant differences between the multi-degree order of urbanization level and the multi-degree order of ecosystem service value in different counties and districts.The results of this paper were conducive to further enriching the theory of interaction between urbanization and ecosystem service value.
