This is the digital journal where they're constructing their models based on this abiotic data to show what they expect to see.

While both forestry and agriculture are frequently aimed at the harvest of goods, these two management styles take vastly different approaches since the ecosystem being managed have vastly different biotic and abiotic components.

虽然林业和农业通常都以收获货物目标，但这两种理方式采取了截然不同的方法，因所理的生态系统具有截然不同的生物和非生物组成部分。

This enables ecologists to measure the biodiversity of an area, record data on abiotic factors, and even get a good estimate of the complexity of a local ecosystem in comparison to other sampling sites.

这使生态学家能够测量一个地区的生物多样性，记录非生物因素的数据，甚至与其他采样点相比，对当地生态系统的复杂性有一个很好的估计。
