| Abstract: | Site quality is the index of the suitable degree and use value of the site conditions to main species.Site quality evaluation is the foundation to judge and predict the plant suitability or potential productivity of site conditions. Site quality evaluation plays an important role in forest management, forest cultivation and construction of forest management decision support system. Studies of site quality evaluation at domestic and abroad were reviewed. The key technical aspects of site quality evaluation in terms of data acquisition, factor selection, modeling structure and model evaluation were summarized. The developing trend for the future studies on site quality evaluation was discussed. |
