摘要
采用当量因子法修正得到2006—2016年厦漳泉地区生态系统服务价值系数表,并以2006年、2016年Landsat TM和Landsat8遥感影像为数据源,应用ArcGIS趋势分析、区域统计和空间自相关等方法结合地形起伏度探究生态系统服务价值时空分布格局,揭示地区生态环境分布现状。结果表明:厦漳泉地区生态系统服务价值呈'两高一低'、自西向东倾斜的分布格局,并有沿东北—西南方向延伸的趋势;大部分区域处于中等价值水平,受地形梯度效应作用,集中分布于山地、丘陵地带。10年间,地区生态系统服务价值分布愈加集聚,厦漳泉沿海城镇化区域的'低谷'效应凸显。随格网尺度的增大,生态系统服务价值的集聚程度有波动上升趋势,密集城镇化地区生态系统服务价值的损失愈加显著。
The equivalent factor method was used to correct the coefficients of ecosystem service value for Xiamen-Zhangzhou-Quanzhou region from 2006 to 2016 and the data sources were from Landsat TM and Landsat8 remote sensing images in 2006 and 2016.The value of average ecosystem service was obtained by interpreting land use type maps and spatial gridding methods.Using ArcGIS trend analysis,regional statistics,and spatial autocorrelation,we explained the spatiotemporal pattern evolution of ecosystem service value based on relief amplitude and revealed the current status of regional ecological environment distribution.The results indicated that the distribution of ecosystem service value in Xiamen-Zhangzhou-Quanzhou region showed a pattern of‘two highs and one low’with a tilting trend from west to east,and extending in the northeast-southwest direction;ecosystem service values were at a medium-value level in most regions,and were affected by topographic conditions,ecosystem service values were concentrated in mountainous and hilly areas.In the past 10 years,the distribution of regional ecosystem service value had become increasingly concentrated and the‘low valley’effect of the urbanization areas along the coast of Quanzhou-Xiamen-Zhangzhou gradually had become more obvious.In addition,as the scale of grid increased,the degree of agglomeration of ecosystem service value showed a fluctuating upward trend;moreover,the loss of ecosystem services value in highly urbanized areas was becoming more significant.
