Background: What are now increasingly called individual based models (IBMs) have been used in ecology since the 1970s when theoretical ecology began in earnest. The best known examples from that time include the forest computer simulation model (named JABOWA) of Daniel Botkin (Botkin et al 1972) and the computer simulation model of Donald DeAngelis (DeAngelis et al 1991) for a freshwater fish c...
In this paper, the rare earth mining area of southern Ganzhou in Jiangxi Province, China is taken as a study area. And the ecology quality evaluation mode based on remote sensing technology was built up to assess the ecology equality status of the opencast mine area. In order to determine the influence sphere on the surrounding ecology quality, the buffer zone method was introduced. The result ...
The use of the metabolism concept, expanded to include aspects of livability, is applied to cities to demonstrate the practical meaning of sustainability. Its application in industrial ecology, urban ecology, urban demonstration projects, business plans and city comparisons are used to illustrate its potential. # 1999 Elsevier Science B.V.

The field of restoration ecology represents an emerging synthesis of ecological theory and concern about human impact on the natural world. Restoration ecology can be viewed as the study of how to repair anthropogenic damage to the integrity of ecological systems. However, attempts to repair ecological damage should not diminish protection of existing healthy ecosystems. Restoration ecology all...
