Research Progress in Decision-making Factors and Methods for Forest Road Network Planning
As a network structure that connects various parts of forest and provides accesses to resource utilization,forest road networks play an important role in forest management,ecological conservation and sustainable development.In recent years,the study of forest road networks has received extensive attention in multiple disciplines,providing new perspectives and methods to address the challenges facing forest management and conservation.Based on the theoretical development and planning dimensions of forest road network,the paper reviews in a systematic manner the research at home and abroad on the decision-making variables and methods for forest road network planning.The decision-making factors include technical variables,environmental variables,economic variables,and social variables,and the planning methods cover spatial multi-criteria methods,exact algorithmic methods,and heuristic algorithmic methods.At the end,we look into the future research from four aspects,i.e.,the research on the relationship between forest road network and carbon density,the research on forest road network planning oriented to forest species,the research on sustainable planning of forest roads,and the research on multifunctional agglomeration of forest road network,so as to provide the theoretical support for forest road network planning in the context of forestry development in the new era.
