Forest Health Assessment in Typical Natural Secondary Mountain and Stony Forest Communities of Northern China
摘要
Abstract
In order to objectivily evaluate forest health,typical natural secondary mountain and stony forest communities of northern China was carried out.Based on qualitative analysis of existing data,12 indices which were divided into 3 categories were determined as the assessment indexes of forest ecosystems health in the study area.Based on the combination of qualitative analysis and quantitative analysis,forest health assessment indicator system was established.The system includes structural indicators,functionality indicators and anti interference indicators.Step analysis method was adopted to confirm the weight of each indicator,100 subcompartments were assessed by using assessment model for forest health in the study area.Results showed that most of these forest subcompartments were in healthy condition in the study area.The area was 29 600 m2,accounting for 74.0% of the sample area.Therefore,feasible measures also should be taken to improve forest management level,to make the forest structure more stable,anti-interference and vigor,and to reach the ideal structure of forest community health.关键词
