Degraded Forest and Grassland Restoration Patterns in Hengshan District
Starting from the current situation of degraded vegetation in Hengshan District,this paper explores the degradation characteristics of major forest and grass species such as poplar(willow),Mongolian pine(Chinese pine,arborvitae),and shrubs.It analyzes the main forms of forest and grass vegetation degradation and identifies the subjective and objective factors causing the degradation,such as drought,lack of rain,physiological overripe-ness,and poor economic management.Targeted restoration technologies for degraded forests and grasslands are pro-posed,including renewal and reconstruction,selective cutting and replenishment,regeneration under the canopy,quality improvement and efficiency enhancement,tending and transformation,crop restoration,fencing,forest management,and grassland improvement.Eleven mixed planting patterns are explored for enhancing the quality and efficiency of existing coniferous trees,broadleaf trees,and shrubs.
