To deeply understand the current growth conditions and precisely simulate future growth patterns of the forest ecosystem,we need a clear assessment of the responses of tree growth(including both the interand intra-annual cambial activity as well as the phenology)to climate change.Meanwhile,the detailed relationships between intra-annual tree radial growth and climate parameters could enrich our present knowledge extracted from the traditional dendroclimatological or dendroecological studies.However,there are still limited methods or technologies to directly monitoring the response of tree radial growth to climate change on the intra-annual scale at present.Due to its unique advantages,microcoring method has been widely used during the past years,especially in the Europe and Canada region of North America.While for the other regions, such as the tropical or Asia areas,only limited researches can be found.On the other hand,the microcoring method has been successfully used to directly monitoring tree radial growth and also used for comparing the different effects of ageing,altitude and health.Furthermore,how tree radial growth will respond to various controlling experiments,such as warming/cooling,drying and thinning,has also been studied in some regions. Herein,we give a detailed overview of the above contents.
