摘要
以松花江流域哈尔滨段为研究区域,采用生态系统服务价值(ESV)区域修订模型计算ESV,对区域ESV时空变化特征及空间相关性进行研究,计算区域ESV数量与空间分布均匀度及变化.结果表明:①研究区域ESV存在很强的空间相关性,不同年份各级别ESV分布差异不大;②1995年、2005年和2015年不同等级ESV在数量分布均匀度上呈现先减小后增加的变化,均匀度都比较低;③各等级ESV空间分布不均匀,低值ESV空间分布均匀度均大于0.7,在研究区域内空间分布均匀,其余各等级ESV空间分布均匀性均小于0.5,都处于不均匀分布状态,三期ESV平均空间分布均匀度呈现先增加后减小的变化.
Taking the Harbin section of Songhuajiang River basin as the research object,the spatial and temporal variation characteristics and spatial autocorrelation of ESV in the study area are studied,and the number of ESV in the study area and its spatial distribution uniformity and variation are calculated.The results show that there is a strong spatial correlation of ESV in the study area,and there is no significant difference in the distribution of ESV in different years.In 1995,2005 and 2015,the distribution uniformity of different grades of ESV first decreases and then increases,and the evenness is relatively low.The spatial distribution of ESV in each grade is uneven,and the spatial distribution uniformity of low value ESV is greater than 0.7.The spatial distribution uniformity of ESV in the study area is uniform,and the spatial distribution uniformity of other grades of ESV is less than 0.5,which is in a state of uneven distribution.The average spatial distribution uniformity of ESV in the three stages shows an increase and then a decrease.
