摘要
文章采用基于动态评估方法构建的单位面积价值当量因子,对深圳市的生态系统服务价值进行评估;利用景观格局指数对该区的景观格局演变进行分析,研究景观格局变化对生态系统服务价值的影响。结果表明:该区2000-2015年的生态系统服务总价值增加了86.81亿元;林地和建设用地是深圳市的主要景观类型,景观结构趋于稳定。由此可见,近年来深圳市重视对生态用地的保护,在经济与生态的协调发展中起到较好的示范作用。
In this paper,the value equivalent factor of unit area based on dynamic evaluation method is used to evaluate the ecosystem service value of Shenzhen City;and the landscape pattern index is used to analyze the evolution of landscape pattern in the area,and the impact of landscape pattern change on ecosystem service value is studied.The results show that the total value of ecosystem services in this area increased by 8.681 billion yuan from 2000 to 2015;woodland and construction land were the main types of landscape in Shenzhen,the landscape structure tended to be stable.Thus it can be seen that in recent years,Shenzhen has attached great importance to the protection of ecological land,which has played a good demonstration role in the coordinated development of economy and ecology.
