Abstract: Kuaiji Mountain is the original producing area of Torreya grandis. T. grandis has a long history with profound culture, unique value, ancient grafting technique and vital agro-heritage. Research on the ecosystem services value of ancient T. grandis in Kuaiji Mountain was necessary to further understand the important agro-heritage and develop corresponding protective measures. Based on literature and available data, this paper comprehensively evaluated the ecosystem services of ancient T. grandis group resources in Kuaiji Mountain in terms of supply, regulation, culture and support. The research showed that total integrated ecosystem services value of ancient T. grandis was 8.614×10⁵ Yuan·hm^-2·a^-1. Of this among, supply function (such as forest by-product, etc.) was 3.686×10⁵ Yuan·hm^-2·a^-1, regulation function (such as soil/water conservation, climate regulation, environment purification, etc.) was 2.078×10⁵ Yuan·hm^-2·a^-1, cultural function (such as heritage, tourism, humanistic, research, etc.) was 2.845×10⁵ Yuan·hm^-2·a^-1, and support function (such as habitat, nutrient cycle, etc.) was 489 Yuan·hm^-2·a^-1. The ancient T. grandis group resources in Kuaiji Mountain not only had economic value, but also ecological value. Economic value was an important resource for economic forests and tourism which also promoted local sustainability of economic development. Ecological value benefited soil/water conservation and protected biodiversity. Ancient T. grandis group resources also exhibited cultural value which was inheritance of the origin and culture of the resource. As a crucial agro-heritage, the dynamic protection of ancient T. grandis group resources was beneficial to the protection and rational utilization of local resources. It also promoted a coordinated development of the local economy, environment and culture.
