Abstract:

The silviculture and management of industrial plantation is crucially related to strategy safety of wood production. The decline mechanism and long-term productivity maintenance technology of replanted plantation were hotspots in forestry research. According to the research tendency of decline mechanism of replanted plantation, three hotspots such as allelopathy, nutrient cycling and root turnover, were discussed in this article. Through establishing a conceptual model about decline mechanism of replanted plantation, the relationship among different ecological factors was discussed to reveal the decline mechanism of replanted plantation was induced by multi-factors. This thesis was expected to be reference for the future researches about decline mechanism of plantation.

Key words: replanted plantation; productivity decline; allelopathy; nutrient availability; root turnover
