Journal Introduction
Forestry Science Research is a comprehensive academic journal of forestry science sponsored by the Chinese Academy of Forestry Science. The main task is to timely reflect the latest research results, academic papers and reports, scientific and technological trends and information of forestry science with the Chinese Academy of Forestry as the main body, to promote academic exchanges at home and abroad, to carry out academic discussions, to prosper forestry science and to better serve China's forestry construction. The main contents are: forest seeds, seedling raising and afforestation, forest plants, forest genetic breeding, tree physiology and biochemistry, forest insects, resource insects, forest pathology, forest microorganisms, forest birds and animals, forest soil, forest...
Geographical variation of tree species population is the basis of tree selection and breeding. It is of great significance to study the climate sensitivity of radial growth of different provenances for seed allocation and selection of superior provenances. This paper reviews the long-term and short-term responses of radial growth of different provenances to climate change, suggesting that the response characteristics to climate change vary among different provenances. The response of radial growth of different provenances to climate change can be used to guide provenance selection in the future climate. However, there is still a lack of research on the response of different provenances to climate change, and the response of provenance growth to climate change needs to be further studied. Using the method of dendroclimatology to explore the response of radial growth of different provenances to climate change can effectively promote forest cultivation management and guide the selection of productive and adaptable seed sources for reforestation.

:[ Objective ] To explore the soil fertility of forest land in the main production area of Carya dabieshanensis, and provide basis for soil management and scientific fertilization of forest land of C. dabieshanensis. [ Method ] 88 soil samples were collected from the main producing areas of C. dabieshanensis in Jinzhai County, Huoshan County and Luotian County. According to the indicators of pH, organic matter, Total N, Toal P, Total K, Available N, Available P and Available K, the soil fertility was evaluated by fuzzy comprehensive evaluation method, and its content and variation were analyzed. [ Results ] The average soil pH value of Carya dabieshanensis was 5.19; The contents of soil organic matter, Total P, Available N and Available P were generally rich, with an average of 53.11 g·kg−1, 0.99 g·kg−1, 179.41 mg·kg−1 and 21.30 mg·kg−1, respectively. The average value of Total N was 1.02 g·kg−1, at a medium content level. The contents of soil Total K and Available K were relatively deficient, with an average of 8.24 g·kg−1 and 71.52 mg·kg−1. The average value of comprehensive index of soil fertility (IFI) of C. dabieshanensis was 0.61. Both Grade II and III soils accounted for 50.00%. Principal component analysis showed that organic matter, Available N, Total P, Available P, pH and Total K were the most important factors affecting soil comprehensive fertility. [ Conclusion ] The comprehensive soil fertility of forest land in C. dabieshanensis is generally high. The contents of organic matter, Available N and phosphorus are rich, the pH value is acidic, and potassium is deficient. Soil management should improve the soil to increase the pH value, increase potassium fertilizer, maintain phosphorus fertilizer and reduce the use of nitrogen fertilizer.
