Abstract:

How to select appropriate target tree species used for constructing typhoon- and frost-resistant plantations is one of challenges in afforestation practice in the mountains area along coast. In this study, the typhoon- and frozen-damaged plantations of Cryptomeria fortunei in each of sloping face and concave slope area were reconstructed by planting functionally target-oriented tree species in Pan mountains of Tiantong region, Zhejiang province. Those tree species were selected based on their functional traits, including the strength in mechanical and frozen resistance. Variation in growth of functionally target-oriented species and forest structure were investigated after 7 years of site reclamation. The results showed that Cyclobalanopsis gracilis, Cyclobalanopsis gilva, Cyclobalanopsis myrsinaefolia, and Schima superba had strong ability of blizzard- and frost-resistance. Within the re-built plantations, the sub-tree layer was formed by the functionally target-oriented species with 5-6 m in height and above 15% in coverage; in the shrub layer, the height and coverage approached 2-4 m and 70%, respectively. The comprehensive importance value of the functionally target-oriented species was above 50% and 70% respectively in tree and shrub layer. Compared with the reference site, the growing stock increased 51.8% and 59.6% respectively in sloping face and concave slope area. In conclusion, the blizzard- and frost-resistant plantations constructed with the functionally target-oriented species quickly developed to multiple layers in community structure, and remarkably increased growing stock, thus, improved effectiveness of forest defense against typhoon- and frozen-induced stresses.
