中山市生态保护红线划定及其生态系统服务价值变化研究

Demarcation of Eco-redline in Zhongshan City and Changes in Its Value of Ecosystem Services

以中山市为研究对象,依据该区域生态环境现状,综合考虑区域内重要生态功能区、生态敏感脆弱区和禁止开发区,确定了中山市生态保护红线范围,并对其生态系统服务价值和变化情况进行了评估与分析.结果表明:中山市生态保护红线面积为175.23 km^2,占全市陆地面积的9.82%,主要分布在中南部地区的五桂山周边、长江水库集水区域的生物多样性维护、水源涵养生态功能富集区.2015年,中山市生态保护红线生态系统服务价值为14.82亿元,较2000年略有提升,占全市生态系统服务总价值的12.27%.

Based on the existing ecological environment in the region and a mixture of various influencing factors,such as important ecological function areas,ecologically sensitive and vulnerable areas and the areas excluded from development,the range of eco-redline in Zhongshan was designated.Its value of ecosystem services and relevant changes were also evaluated and analyzed.The results showed that:the areas included within the range of eco-redline in Zhongshan are 175.23 km^2 in total,accounting for 9.82%of the city’s land area.They are mainly distributed around Wugui mountain in the south-central Zhongshan and near ecological function areas for biodiversity and water conservation ecological function enrichment region in the reservoir catchments of Changjiang.In 2015,the value of the city’s eco-redline in ecosystem services increased slightly to 1.482 billion yuan from the figure in 2000,accounting for 12.27%of the total value of the city’s ecosystem services.
