Название: Handbook of ecological indicators for assessment of ecosystem health
Авторы: Jorgensen S.E. (ed.), Costanza R. (ed.), Xu F.L. (ed.)
Аннотация:
The idea to apply an assessment of ecosystem health to environmental
management emerged in the late 1980s. The parallels with the assessment of
human health are very obvious. We go to the doctor to get a diagnosis (to
determine what is wrong) and hopefully initiate a cure to bring us back to
normal. The doctor will take various measurements and make examinations
(pulse, blood pressure, sugar in the urine etc.) before making a diagnosis and
suggesting a cure.
The idea behind the assessment of ecosystem health is similar (see
Figure 1.1). If we observe that an ecosystem is not healthy, we want a
diagnosis. What is wrong? What caused this unhealthy condition? What can
we do to bring the ecosystem back to normal? To answer these questions, and
also to come up with a cure, ecological indicators are applied.
