| 摘要: |
| 文章采集珠江三角洲地区 229 个建制镇的大样本数据进行林地集约利用评价，选取森林覆盖
率、林地生产率、单位面积林木生产量、生态公益林面积比率、商品林面积比率、人均林地 6 个指标构
建评价指标体系，采用归一化法进行样本指标标准化，再结合熵权法确定指标熵值和熵权，计算得到林
地集约利用综合评价值。评价结果显示珠三角非核心区建制镇的林地集约利用水平较高，并进一步探讨
促进林地集约利用的相关对策。 |

| Abstract: |
| This paper collected the large sample data of 229 towns in the Pearl River Delta region and
evaluated the intensive utilization of forest land. The evaluation index system of forest coverage rate, forest
productivity, unit area forest production, ecological public-welfare forest area ratio, commercial forest area ratio
and per capita forest land were selected. The normalization method was used to standardize the sample index,
and then the entropy value and the entropy weight were determined by the entropy weight method, and the
comprehensive evaluation value of forest land intensive utilization was calculated. The evaluation results showed
that the intensive utilization of forest land in the non-core area of the Pearl River Delta was higher, and the
relevant countermeasures to promote the intensive use of forest land were discussed. |
