基于"驻留生态位"杉木天然更新研究进展

Forest natural regeneration is an ecological process of forest restoration and reconstruction using nature,and it is an important way for Chinese fir plantation to realize self-reproduction.At present,forest regeneration in China is still dominated by artificial regeneration,which is affected by many factors such as habitat heterogeneity,provenance,litter,human disturbance and community diversity.With the arrival of the mature period of Chinese fir plantation,the problems of decline and natural regeneration of Chinese fir plantation are gradually emerging,and the regeneration problem has gradually become the main factor for Chinese fir plantation to play its ecological role.In this paper,the research progress of natural regeneration methods and regeneration barriers of Chinese fir plantation were reviewed,and the factors affecting natural regeneration of Chinese fir,such as light,moisture,temperature,soil,litter and disturbance,were emphasized.On this basis,the main problems and shortcomings of the existing research were put forward,and the future research direction was pointed out that the physiological basic research should be strengthened on the early process of Chinese fir regeneration and the renewal of Chinese fir seed and budding tiller.The interference threshold and coordination mechanism of the mutual transformation between seed renewal and tiller renewal of Chinese fir were studied,and the coupling mechanism of the influence factors and interference mechanism of Chinese fir natural renewal was studied,and the comprehensive effects of biological and abiotic factors on natural renewal could be comprehensively considered in the research process.In order to provide some guidance for Chinese fir management practice and promote the healthy and stable growth of Chinese fir stand;The aim is to provide scientific support for promoting forest natural regeneration and realizing forest sustainable development.
