| 摘要: |
| 根据广东省 2005 年、2010 年、2015 年和 2020 年 4 期森林资源档案更新数据，分析了 15 年来广东省林业用地面积、有林地面积、森林覆盖率、森林类别、森林面积和森林蓄积量 6 个主要因子的动态变化，结果显示：林业用地面积减少了 45.12 万 hm2、有林地面积减少了 5.36 万 hm2、森林覆盖率增加了 3.23%、公益林地面积增加了 122.80 万 hm2、商品林地面积减少了 167.92 万 hm2、森林面积增加了58.07 万 hm2、森林蓄积量增加了 23 524.29 万 m3。采用回归分析预测，至 2030 年和 2060 年，森林蓄积量将分别达到 72 023.58 万 m3 和 93 422.46 万 m3。

| Abstract: |
| Based on the updated data of forest resources archives in Guangdong province in 2005, 2010, 2015 and 2020, the dynamic changes of six main factors in Guangdong province in the past 15 years are analyzed.
The results showed that the forestland area decreased by 451 200 hm2, the stand area decreased by 53 600 hm2, the forest category increased by 3.23%, the area of public welfare forest land increased by 1 228 000 hm2, the area of commercial forest land decreased by 1 679 200 hm2, the forest area increased by 580 700 hm2, and the forest stock increased by 235 242 900 m3. Regression analysis predicts that by 2030 and 2060, the forest stock will reach 720 235 800 m3and 934 224 600 m3 respectively. |
