Construction and application of a dendrochronological evaluation method for the stability and suitability of artificial forests in arid areas
In the arid zone of northern China,an important part of the current research on ecological construc-tion is the improvement of ecosystem structure and the stable maintenance and regulation of ecological functions.The evaluation of the stability and suitability of artificial forests in arid zones and the proposed management mea-sures for maintaining the stability of these forests in the context of climate change are of great practical signifi-cance for regional ecological restoration and sustainable development.Based on the relevant research progress in China and abroad,this paper constructed a preliminary stability and suitability evaluation method mainly based on dendrochronological methods for the artificial tree and shrub forests.The evaluation method highlights the ra-dial growth process of trees and analysis of the limiting factors of different environmental factors,supplemented by comparisons of stand growth appearance,forest features,stand conditions and soil moisture status.Targeted conservation management measures to maintain the stability of artificial forests could be proposed based on a comprehensive evaluation of the stability and suitability of artificial forests.The paper also showed examples of the application of several tree species in the Loess Plateau region under different precipitation gradients,forest stand types,site conditions and management practices,and suggested further expansion.
