摘要
介绍了广东省第四次森林资源二类调查的方法、特点,对主要结果及数据变化进行了分析。与广东省第三次森林资源二类调查数据相比,广东省森林覆盖率增加了3.09个百分点,森林蓄积量增加了18727.49万m^3,林业用地面积减少了37.09万hm^2,森林面积增加了73.49万hm2,调查结果表明广东省森林资源主要数据变化较大,森林质量有所提高,但总体质量仍较低,单位面积森林蓄积量仅为60.57 m3/hm^2,森林质量的提升还有较大增长空间,进一步加强森林经营要求十分迫切。
The methods and characteristics of the fourth forest resource inventory in Guangdong Province are introduced,and the results and data changes are analyzed.Compared with the third survey data,forest coverage in Guangdong Province increased by 3.09 percentage point,the forest stock increased by 187.275 million cubic meters,and the forest area increased by 734,900 hectares.The area of forestry land decreased by 370,900 hectares as a result of the increase in accuracy and reduction of recalculated area.The data also indicates that the major data of forest resources in Guangdong Province have changed greatly,and the quality of forests has improved,but the overall quality is still low with forest stock of 60.57 m3/hm2,and there is still large potential for improvement in forest quality.
