摘要:

依据《森林生态系统服务功能评估规范》(GB/T 38582—2020)和《自然资源(森林)资产评价技术规范》(LY/T 2735—2016)的理论和方法,结合广东省惠州市森林资源规划设计调查成果和监测数据,对惠州市森林生态系统的涵养水源、防止土壤侵蚀、固碳释氧、净化大气环境、森林防护、生物多样性保护、森林游憩等7项生态系统服务功能及其价值进行定量评估,旨在摸清惠州市森林生态家底,为实施森林生态系统分区管理、划定生态保护红线、生态保护财政转移支付、政府生态环境绩效评估考核、生态保护和恢复工程等提供科学依据。研究结果表明,惠州市森林生态服务价值量为441.38亿元/a,按其服务功能价值大小排序为水源涵养>生物多样性>固碳释氧>防止土壤侵蚀>净化大气环境>森林防护,其中,水源涵养、生物多样性价值之和占总价值的77.65%,是惠州市森林生态系统的主要服务功能。

Abstract:

Based on the theories and methods of the "Specifications for Assessment of Forest Ecosystem Services"(GB/T 38582—2020) and the "Norm of Techniques for Valuation of Forest Resources Assets"(LY/T 2735—2016),and in combination with the survey and monitoring data of forest resources planning and design in Huizhou City,Guangdong Province,quantitative assessments were conducted on seven service functions and their values of forest ecosystems,including water source conservation,soil erosion prevention,carbon sequestration and oxygen release,atomospheric purification,forest protection,biodiversity conservation and forest recreation.The aim was to understand the forest ecological foundation in Huizhou City,and provide scientific basis for forest ecosystem zonation management,ecological conservation red line identificatin,fiscal transfers for ecological conservation,government ecological environment performance evaluation,ecological conservation and restoration projects,etc.The study shows that the forest ecological service value in Huizhou City is 44.138 billion yuan per annum,and the service function values are ranked in the following order:water source conservation>biodiversity conservation>carbon sequestration>soil erosion prevention and oxygen release>air purification>forest protection.Water source conservation and biodiversity conservation together account for 77.65% of the total value,and are the main service functions of forest ecosystems in Huizhou City.
