摘要/Abstract

摘要： 广东省是国家森林城市最多的省份之一,各地级市均已加入建设森林城市行列。掌握广东省生态环境质量(EEQ)的时空分布状况,有助于城市建设与生态系统的良性互动和协调发展。本研究利用基于水效益的生态指数(WBEI)实现了广东省EEQ的快速监测,分别采用标准差椭圆和重心迁移、Theil-Sen Median趋势法和Mann-Kendall检验探索其空间分布差异与变化趋势,并分析了EEQ和城镇化的耦合协调情况。结果表明: 利用归一化植被指数所得的WBEI能更好地反映广东省植被覆盖情况,并客观地评估水域周边及城市植被EEQ。广东省北部内陆地区EEQ总体优于南部沿海地区,在西南-东北方向上分布更为集中,重心整体“先向西南、后向东北、再向西南”移动。大部分地级市EEQ保持稳定或有所改善,改善型和退化型相间分布在全省各地区。广东省南部地区EEQ与城镇化的耦合协调度高于北部地区,耦合协调度不断提升。珠三角森林城市群是耦合协调度高值区域,在推进EEQ与城市建设协调方面具有良好的辐射带动作用。本研究可为多水域森林型城市EEQ评价提供方法参考。

Abstract: As one of the provinces with the largest number of national forest cities, all prefecture-level cities in Guangdong Province have joined the campaigns of building forest cities. Mastering the spatial and temporal variations of ecological environment quality (EEQ) in Guangdong Province is conducive to the benign interaction and coordinated development of urban construction and ecosystem. We used the water benefit-based ecological index (WBEI) to achieve rapid monitoring of EEQ in Guangdong Province, utilized the standard deviation ellipse and gravity center migration, Theil-Sen Median trend method and Mann-Kendall test to explore the spatial distribution disparities and trends, and analyzed the coupling coordination between EEQ and urbanization. The results showed that the WBEI derived from the normalized difference vegetation index could better reflect vegetation coverage in Guangdong Province, and objectively evaluate the EEQ of watersheds and urban vegetation zones. The EEQ in the northern inland area was generally better than that in the southern coastal area, and it was more concentrated in the southwest-northeast direction. The gravity center position displayed a sequential movement from southwest to northeast and then back to southwest. Most prefecture-level cities remained stable or improved in EEQ, while the improved and degraded types were distributed in various regions of the province. The coupling coordination degree between EEQ and urbanization in southern Guangdong Province exceeded that of the northern region, with the coupling coordination degree being constantly improving. The Pearl River Delta Forest City Cluster emerged as a region characterized by high levels of coupling coordination, with a good radiation driving effect in promoting the coordination of EEQ and urban construction. This study could provide a method reference for EEQ evaluation within multi-watershed forest cities.
