Two detailed investigation of Public Welfare Forest resouce in 1999 and 2008 ,using the method of comparative analysis and mathematical statistics, dynamic change of public welfare forest resources in Liandou Lishui,Zhejiang were studied, from which the Dynamic change of forest age, crown density, density, forest type, etc were mastered. Through ten years construction from 1999 to 2008, the area proportion of Young mid-maturation forest and mature or over-mature forests was changed from 78:22 to 40:60, meanwhile the stand volume proportion was changed from54:46 to 23:77;the Low canopy density (crown density is less than 0.7) forest decline from 76.57%to 25.14%,the high canopy density stand has increased from 23.43%to 23.43%;Broad-leaved forest area proportion increased from 11.43%to 11.57%, mixed needle leaf area proportion increased from 26.86%to 40.29%;Average stand volume increased from 25.65 m3·hm-2 to 37.95 m3·hm-, which has an annual net gain of 4.30%.关键词
