Forest Health Assessment of Cangshan World Geopark in Dali City
In this paper,based on the data from 2016 Forest Resources Class Ⅱ Survey of Cangshan World Geopark in Dali City,a for-est health assessment index system was established at the forest subcompartment level with 13 indexes in 4 aspects including the stand growth factors,topographic factors,soil factors and conservation condition,using the analytic hierarchy process (AHP).The forest health assessment of the geopark was made with the comprehensive index method.The results showed that 46.99% of the geopark area was classified as the excellent grade,9.65% of the area was at the good grade,6.58% was at the medium grade while 5.67% was at the bad grade and 31.10% was in the degradation or lost condition.Patrol,monitoring and conservation should be strengthened for the ex-cellent-grade forests.Restoration measures including afforestation and soil conservation should be adopted for good-grade and medi-um-grade forests while ecological restoration should be implemented for the bad-grade forests to prevent the spread of the poor condi-tions to other areas.Comprehensive management measures should be taken to restore and regenerate the degraded forests.
