绿化斑块合并的景观格局光谱绿化廊道分区

Partition of Landscape Pattern Spectrum Green Corridor Based on Green Patch Merging

在城市景观园林设计中,由于绿化斑块聚集,区域复杂,难以实现对遥感信息光谱特征的有效提取,制约城市景观设计科学规划。提出一种基于绿化斑块合并技术的景观格局光谱绿化廊道分区处理技术,首先进行城市绿化景观格局模型构建,分析城市绿化景观生态风景园林设计的现状,设计绿化斑块合并技术,提出绿色景观格局分析的绿化廊道光谱特征提取算法。实现对城市绿化景观格局的光谱绿化廊道的分区处理方法改进。研究结果表明,该方法能有效对城市景观中的绿化廊道进行特征提取和廊道分区,廊道分区的峰值信噪比提高,为城市景观和风景园林建设提供准确的数据依据。

In the city landscape garden design of the green area, due to plaque accumulation, it is difficult to achieve effec.tive extraction of remote sensing information of spectrum feature, so it restricts the city landscape design of scientific plan.ning. A partition processing technology of landscape pattern of green corridor green plaque with spectral technique is pro.posed based on green patch merging. Improved partition processing achieves the spectral green corridor on city greeninglandscape pattern. The results show that, this method can effectively complete the city landscape greening corridors for fea.ture extraction and corridor partition, it can improve the peak signal to noise ratio of corridor partition, it provides accuratedata for the city landscape and the landscape construction.
