| 为实现城郊森林公园的森林资源保护和休闲游憩服务双重目标, 文章以广东云勇国家森林公
园为例, 基于 QuickBird 影像进行目视解译, 开展景观类型与景观功能分类, 利用熵权法确定指标权重,
通过网格分析法 (采样单元为 33 m×33 m) 和空间插值法分析功能特征下景观健康的空间分布, 通过
ArcGIS 软件分析景观健康影响因素的阈值区间。 结果表明, 1) 公园景观的 “非常差” 与 “较差” 健康
等级的区域呈面状分布 (占比 93. 40% ~ 98. 81%), “非常好” 与 “较好” 等级主要呈块状、 点状分布在
园区西北部 (占比 0. 18% ~2. 53%)。 2) 公园生态保护与游憩利用功能景观的不同健康等级面积比有差
别, 其中生态保护功能景观的 “非常好” 与 “较好” 健康等级的面积比高于游憩利用功能景观同等级比
值的 2. 13%。 3) 随着景观健康等级升高, 森林与非森林景观面积比、 数量比总体呈波动下降趋势, 当面
积比值范围为 0. 39~0. 54, 数量比值为 1. 5, 综合功能景观的健康等级最高。 为提升城郊森林公园的景观
健康水平, 建议甄别生态保护和游憩利用功能的独立区与叠合区, 实施差异化的保护利用, 并采取功能
协同设计, 加强生态保护和游憩利用功能之间的协同发展。 |

| Abstract: |
| Assessing landscape health is the key to achieving the dual objectives of forest resource conservation and recreational services in suburban forest parks. Taking the Yunyong National Forest Park in Guangdong
Province as an example, this article conducted a visual interpretation based on QuickBird images to classify landscape types and landscape functions. The entropy weight method was used to determine indicator weights. Grid
analysis (with a sampling unit of 33 m×33 m) and spatial interpolation were employed to analyze the spatial distribution of landscape health under functionalities. The threshold range of landscape health influencing factorswas analyzed through ArcGIS software. The results indicated that: 1) Regions with " very poor" and " poor"
landscape health grades exhibited a sheet-like distribution pattern, covering approximately 93. 40% to 98. 81%
of the total area. In contrast, regions with "very good" and "good" grades were primarily located in block-like
or dot patterns in the northwestern region of the park, accounting for approximately 0. 18% to 2. 53% of the total
area. 2) Some differences were observed in the area ratios of landscape health grades between eco-conservational and recreational landscapes within Yunyong National Forest Park in Guangdong Province. The area ratios of
"very good" and "good" landscape health grades for eco-conservational landscapes were higher than those of the
same grades for recreational landscapes, with a 2. 13% difference. 3) As the landscape health grade improved,
the forest / non-forest area ratio and quantity ratio generally exhibited a fluctuating downward trend. The comprehensive function landscape health grade was highest when the area ratio ranged from 0. 39 to 0. 54 and the
quantity ratio was 1. 5. To enhance the landscape health level of suburban forest parks, it is recommended to identify areas where eco-conservation and recreational functions exist independently and where they overlap, implement differentiated protection and utilization measures, and adopt collaborative functional design to strengthen
the collaborative development between eco-conservation and recreational functions. |
