Abstract:

It is significant for the scientific protection of forest shelterbelts and the formulation of sustainable management measures for forest shelterbelts.This can be achieved by researching and establishing health quality standards as well as assessment systems of forest shelterbelts,studying the health status of the forest area in the Yulin sandy region of Mu Us,and reasonably evaluating the health of the forest shelterbelts.Different types of forest shelterbelts in the Yulin sandy region of Mu Us were studied by using Analytic Hierarchy Process and Cluster Analysis to construct a health assessment system.The results show:1)The forest shelterbelt health assessment indicator system in Yulin sandy region of Mu Us is divided into 5 levels,including health(0.70~1.00),micro degradation(0.60~<0.70),mild degeneration(0.50~<0.60),moderate degradation(0.40~<0.50),Severe degradation(0~<0.40).2)According to analysis and assessment,the result shows the relatively bad health status of forest shelterbelts in the Yulin sandy region,which is belonged to the mild degeneration and moderate degradation.It is recommended to strengthen the management and protection of forest shelterbelts in the Yulin sandy region and reduce human and animal damage.This will achieve sustainable development and utilization of the forest shelterbelt in the Yulin sandy region of Mu Us.

Key words: Yulin Sandy Region of Mu Us, forest shelterbelt, analytic hierarchy process, health assessment, indicator system
