Health grading evaluation of artificial Haloxylon ammodendron forests on the northeast edge of Ulan Buh Desert
摘要
Abstract
Artificial forests of Haloxylon ammodendron are the largest windbreak and sand-fixing forests widely used in the northeast edge of the Ulan Buh Desert,China.An accurate assessment of the health status of this for-est is crucial for ensuring its functioning,ecological protection,and implementing precise restoration methods.A quantitative health evaluation system based on the framework of"zoning classification grading"involving eco-surveys and a combination of weighted technique for order preference by similarity to ideal solution(TOPSIS)models,was applied.The results revealed that constructing a health evaluation system based on forest and com-munity structure,environmental conditions,and health risks as the criterion layer can ensure accurate estimations.The contribution of factors such as soil moisture content,length of newly formed branches,mortality rate,shoot withering rate,and pests and diseases to such a system is significant.These artificial forests are generally in a moderately degraded state and may progress toward severe degradation.This phenomenon is a result of a combi-nation of factors,including abnormal soil hydration conditions,low soil organic matter content,frequent occur-rence of pest infestations and diseases,and inadequate maintenance and management.These results can provide a scientific basis for the ecological protection and restoration of artificial H.ammodendron forests in the region,as well as references for health assessments and the graded restoration of deteriorated forests as a part of the"Three North"project.关键词
