摘要:

研究和建立防护林健康质量标准和评价体系,掌握毛乌素榆林沙区防护林健康状况,合理评价防护林健康状态对科学保护防护林资源和制定防护林可持续经营管理措施具有指导意义。以毛乌素榆林沙区防护林不同立地类型为研究对象,采用层次分析法,构建毛乌素榆林沙区防护林健康状况评价体系。结果表明:1)毛乌素榆林沙区防护林健康等级划分为5个,分别为健康(0.70~1.00)、微度退化(0.60~<0.70)、轻度退化(0.50~<0.60)、中度退化(0.40~<0.50)、重度退化(0~<0.40);2)毛乌素榆林沙区防护林健康状态总体偏低,属于轻度退化到中度退化,与实际调查结果基本相符。应加强毛乌素榆林沙区防护林的人为管护,减少人畜对防护林的破坏,以实现毛乌素榆林沙区防护林可持续发展与利用。

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.
