Health Assessment of Polar-Birch Secondary Forests in Jingouling
摘要
Abstract
A scientific,rational,and practical health assessment index system for secondary forests were established to provide a reference for the objective evaluation. The experiment was conducted in Jingouling Forest Farm,Jilin Province, China. The general health status of 912 polar-birch secondary stands in the farm was assessed. Based on data of the second type of forest resources survey, factors for the assessment were screen by the method of expert consultation,and then they were weighed by analytic hierarchy process to get threshold values. The results showed that 0. 76% of total assessment areas were unhealthy,80. 49% were sub-healthy,and 18. 75% were healthy. No high quality or disease-free stands were found,indicating that the secondary forests in the farm were in a sub-healthy condition. To improve the health situation, dominant factors should be determined to guide the further management of the stands.关键词
