摘要
针对当前应用于持续性的全国城市体检评估中城市森林数据较为缺乏等问题,该文基于高精度地理国情监测数据,将植被类型、郁闭度或树冠盖度、图斑规模3个特征作为城市森林制图的重要依据,以北京城六区为例,利用制图综合中聚合方法和景观生态指标模型探索城市森林图斑间最适聚合距离,并利用对比分析法验证城市森林制图结果的合理性。结果表明,该方法获取的城市森林制图结果具有高精度、完整性等特征,能够满足持续性的全国城市体检评估工作需求。
Aiming at the lack of urban forest data in the current continuous national urban physical examination evaluation,this article used high-precision geographic national conditions monitoring data to take the three characteristics of vegetation type,canopy closure or canopy coverage,and patch size as the important basis for urban forest mapping.Based on a case study of the six districts of Beijing,this article proposed to use the aggregation method in cartographic synthesis and the landscape ecological index model to explore the optimal aggregation distance between urban forest patches,and adopt the comparative analysis method to verify the rationality of the urban forest mapping results.According to the results,the urban forest mapping results obtained by this method had the characteristics of high precision and completeness,and could meet the needs of continuous national urban physical examination evaluation work.
