摘要:
[目的] 分析石漠化地区生态系统服务价值与经济的空间耦合关系,为石漠化地区生态环境保护与社会经济协调发展提供依据。[方法] 以贵州省盘州市为例,基于格网尺度,计算了研究区生态服务价值(ESV)与国内生产总值GDP,并利用耦合协调模型,对两者间的耦合协调发展程度进行定量评估。[结果] ①盘州市ESV热点区主要分布在东北部的几个少数民族乡镇,冷点区主要分布在经济发展较快且城市化率较高的区域;②盘州市GDP在空间上呈现出局部高的特点,高值区主要集中在石桥镇、亦资街道、翰林街道等工业镇和政治、经济、文化中心;③盘州市ESV与GDP耦合协调度值较低,空间上存在明显的自相关性,耦合协调度较低的区域主要分布在盘州市东南部、北部以及中部;④盘州市ESV与GDP耦合协调度类型以严重失调衰退经济损益型为主,占区域总面积的79.95%。[结论] 盘州市ESV与GDP在空间上存在一定矛盾,耦合协调度较低,兼顾生态环境保护与经济发展有助于提升协调度。

Abstract:
[Objective] The spatial coupling relationship between the ecosystem service value and regional economy was analyzed to provide the basis for coordinated development of environmental protection and social economy in rocky desertification areas.[Methods] Based on the grid scale, the coupling coordination model was used to quantitatively evaluate the degree of coordinated development of ecological service value (ESV) and gross domestic product (GDP) in Panzhou City of Guizhou Province.[Results] ① The ESV "hot spot" area was mainly distributed in the minority villages and towns in the northeast, and the "cold spot" area was mainly distributed in the areas with rapid economic development and high urbanization rate. ② The spatial distribution of GDP in Panzhou City was characterized by its local high, and the high-value areas were mainly concentrated in industrial towns or economic and cultural centers, such as Shiqiao Town, the Yizi Subdistrict, and the Hanlin Subdistrict. ③ The overall distribution of ESV and GDP coupling coordination in Panzhou City was low, there was evident autocorrelation in the space, and the regions with low coupling coordination were mainly distributed in the southeast, north, and central parts of Panzhou City. ④ The type of coupling coordination between ESV and GDP in Panzhou City was mainly a severe imbalance type, accounting for 79.95% of the total area of the region.[Conclusion] Considering the low degree of spatial coupling of ESV and GDP in Panzhou City, balancing environmental protection and economic development would help to improve the coordination.
