摘要
初级生产力是描述生态系统功能和稳定性的重要参数之一,但目前尚无定量估算水电工程占地对评价区生态系统初级生产力影响的适用方法。提出多个群落组成的生态系统加权平均净初级生产力的概念,用于定量估算水电站等各类工程占地对评价区生态系统净初级生产力的影响,并以川西某在建大型水电站的永久占地数据为例子,对方法的应用作了说明。该方法同时适用于评价水电或其他工程占地引起陆生和水生生态系统净初级生产力的变化。
The primary productivity is one of the important parameters characterizing the functions and stability of ecosystem, but there is no method available to estimate the impacts of land use of hydropower project on primary productivity of assessed ecosystem at present. A concept of Weighted Mean of Net Primary Productivity of ecosystem which is composed by some communities is presented to quantitatively estimate the impacts of land use on net primary productivity of ecosystem. The data of permanent land use in a huge hydropower project under construction in western China are used as an example to illustrate the application of this method. The method may be also used to assess the changes of net primary productivity of both aquatic and terrestrial ecosystems caused by land use of hydropower projects or other projects.
