摘要
为充分体现河流生态系统形成和维持的人类赖以为生的自然环境条件和效用,在分析河流生态系统服务功能后,优化了固碳等功能的计算,基于功能价值法,提出了一套涵盖功能较全面、计算较科学合理的河流生态系统服务价值(ESV)评估方法,并利用该方法研究了溧阳市南河ESV。结果表明,溧阳市南河2019年总ESV为12.42×108元,调节、支持、供给、文化功能价值分别占76.5%、12.2%、11.1%、0.2%,为自然资源资产核算和生态补偿标准提供了参考。
In order to fully reflect the natural environmental conditions and effects formed and maintained by the river ecosystem,which is the basis of human life,after in-depth analysis of the river ecosystem service function,the calculation method of carbon fixation and other functions was optimized.Based on the functional value method,a scientific and reasonable river ecosystem service value(ESV)evaluation methods covering more comprehensive functions was proposed,and Nanhe River ESV in Liyang City was studied with an example.The total ESV of Nanhe River in 2019 is 1.242 billion yuan,with the value of regulation,support,supply and cultural functions accounting for 76.5%,12.2%,11.1%and 0.2%respectively,which can provide reference for natural resource asset accounting and ecological compensation standards.
