摘要
标准化生态服务价值评估方法研究滞后,传统方法主观性较强,总量计量沿用简单线性加总方法,不符合农业生态系统服务的复杂网络特性,导致农业生产过程中过度关注经济价值而常忽略生态服务,难以保障农业生态系统的良性循环。文章以河南省为例,根据社会、经济和环境因素界定农业生态系统服务类型,然后筛选并改进服务价值评估方法,运用专家调研结合生态系统服务的复杂网络特性,定量分析了上述服务类型的权重,最终运用非线性总量方法测算河南省农业生态服务价值总量。其结果比传统总量方法计量结果低了2.01倍,有效剔除了价值重复核算部分。
The research on estimation method of standardized agro-ecosystem smwiees value is hysteretie, and traditional methods are very subjective. Simple linear addition method applied to total amount measurement is not suitable for the complex framework characteristics of agricultural ecosystem services, thus leading to too much attention to commercial value and frequent neglect of ecological service, which makes it difficult to guarantee a virtuous circle of agricultural ecosystem. This paper firstly takes Henan Province as an example to define the types of agro-ecosystem services according to such factors as society, economy arid enviromnent. And then the paper screens and improves the service value assessment method, utilizing the combination method of ~pecialist research and complex framework characteristics of ecosystem services to quantitatively analyze the weights of the above lypcs of services. Finally, the paper uses non-linear tntal amount method to estimate the total value of Henan Province＇s ag- ricultural ecosystem services, and the outcome is 2.01 times lower that that of the traditional measurement method, thus effectively eliminating the part of duplicated vahm accounling.
