Evaluation of Agricultural Multi-Functional Value of the Living Ancient Torreya grandis Community in Kuai Ji Mountain

Torreya grandis is an ancient species of arbor tree native to China and a rare economic species in the world as well. Currently, the ancient T. grandis community in the Kuai Ji Mountain has been listed as candidate site of the global agro-cultural heritage and important agro-cultural heritage of China. Based on the features of the ancient T. grandis community, an overall evaluation of the agricultural multi-functions of the forest was performed from the following five aspects, i.e. economical function, biodiversity conservation function, agricultural landscape conservation function, agro-cultural bequeathment function and ecological environmental protection function, using the agricultural multifunction multi-dimensional evaluation model. Results show that its agro-cultural bequeathment function index is the highest, equaling to 1, its ecological environmental protection index 0.85, its agricultural landscape conservation function index 0.43, and its economic function value and biodiversity protection function index was relatively low, being 0.25 and 0.29, respectively, indicating that the leading function of the ancient T. grandis community in the Kuai Ji Mountain is the agro-cultural bequeathment, which is followed by ecological environment protection function and agricultural landscape conservation functions.
