| 摘 要： | 合理的生态保护空间管控可以有效权衡社会经济发展与生态保护之间的矛盾。重要生态保护空间是区域中最具有保护价值的优质生态产品区,对维持区域生态安全与可持续发展具有重要意义。本文以快速城市化的长三角地区为研究区,利用CASA、RUSLE等生态模型、市场价值法、影子工程法等价值估算方法,估算分析长三角2000—2017年生态系统生产总值（GEP）时空变化格局,采用STARS突变检验,结合自然保护区,尝试提出基于GEP的区域重要生态保护空间识别方法,结果表明：①长三角地区GEP总体呈现上升趋势,从2000年4.61万亿元增长到2017年7.12万亿元,分别为同年GDP的2.06、0.36倍。②三大生态系统服务中,调节服务占比最大,分别占2000年和2017年GEP总值的89.1%、64.9%;供给服务和文化服务2000年占GEP总值比例分别为9.60%、1.33%,2017年分别提升至20.83%、14.31%。③GEP空间分布呈南高北低,平原和沿海区域的单位面积GEP偏低,而山地丘陵地区较高。④长三角地区重要生态保护空间占国土空间面积的12%,其中,江苏、安徽、浙江和上海分别占国土空间面积的11%、12%、13%、13%,与生态保护红线具有较好的空间耦合。 |

| Abstract: | Reasonable ecological protection space can optimize the ecological environment in a certain region, improve ecological function, maintain ecological security, and achieve sustainable development goals. The important ecological protection space is the area with the highest protection value of high-quality ecological products in the region. Taking the rapidly urbanizing Yangtze River Delta region as the research area, this study used CASA and RUSLE ecological models, market value method, and shadow engineering method to estimate and analyze the spatial and temporal changes of gross ecosystem product (GEP) in the Yangtze River Delta region from 2000 to 2017. The sequential t-test analysis of regime shift (STARS) mutation test, combined with nature reserves, identifies important ecological protection spaces in the region. The results show that: (1) The GEP in the Yangtze River Delta region shows an upward trend, from 4.61 trillion yuan in 2000 to 7.12 trillion yuan in 2017, which are 2.06 and 0.36 times of the GDP in the same year. (2) Among the three main ecosystem services, the regulation services are the largest, accounting for 89.1% and 64.9% of the total GEP in 2000 and 2017, respectively. The proportion of supply services and cultural services in the total GEP has increased. (3) The spatial distribution of GEP is high in the south and low in the north, and the unit GEP in the plain and coastal areas is low while that in the mountainous and hilly areas is high. (4) Important ecological protection space in the Yangtze River Delta region accounts for 12% of the territorial space area, of which Jiangsu, Anhui, Zhejiang, and Shanghai account for 11%, 12%, 13% and 13% of the territorial space area, respectively, and have healthy spatial coupling with the ecological protection red line. |
