摘要
生态系统服务功能是指生态系统与生态过程所形成及维持的人类赖以生存的自然环境条件与效用,对人类具有很大的价值,尤其是在生态脆弱的西部地区,生态环境是影响和制约区域经济可持续发展的关键因素。通过采取不同的评估方法对青海省生态系统服务功能价值量分别进行了整体和分项评估,结果表明:整体评估方法得出青海生态价值量约为15428.7亿元/年,分项评估方法得出青海生态价值量约为13849.8亿元/年,但通过多种因素的权衡,最终采用分项评估法得出的青海生态价值量。科学合理的评价青海生态系统服务价值量,能够进一步处理好区域经济发展与生态保护问题,对更好地发挥生态系统的服务功能并使其更好地、持续地为人类服务具有重要意义。
