摘要:
基于大量样方实测数据和高分辨率遥感影像数据，采用异速生长模型与GIS空间分析相结合的方法进行西安森林植被碳密度空间分布特征分析.研究发现，西安五种绿地类型乔木综合指数D表现出：风景区绿地>文教区绿地>居住区绿地>工业区绿地>道路绿地.西安不同类型森林植被乔木层碳密度空间分布不均衡，表现为文教区绿地>风景区绿地>居住区绿地.西安城市居住区森林植被乔木层碳密度集中分布在1.21～3.63 kg/m2；西安城市风景区树木碳密度取值范围介于1.92～13.64 kg/m2；西安城市文教区树木碳密度取值范围介于0.422～94.646 kg/m2，未来西安森林植被具有巨大的固碳潜力，但仍需优化西安森林植被结构，加强城市物种多样性保护，从而更好地发挥森林城市的生态服务功能.
Abstract:
Based on a large number of samples data and high resolution remote sensing image data, analyzing the spatial distribution characteristics of Xi′an forest vegetation carbon density by using a method combining allometric growth model with GIS space analysis. The study found that the five kinds of green space composite index D showed: scenic green space>cultural district green space>residential green space>industrial area green space>road green space. What′s more, the carbon density of different types of forest vegetation in Xi′an showed that cultural district green space>scenic green space>residential green space, and its spatial distribution is imbalanced. Besides, the carbon density of residential forest vegetation ranges between 1.21 kg/m2~3.63 kg/m2；the scenic forest vegetation ranges between1.92 kg/m2~ 13.64 kg/m2, and the cultural district forest vegetation ranges between 0.422 kg/m2~94.646 kg/m2. In the future, the forest vegetation in Xi′an has great potential for carbon sequestration. However, it is still necessary to optimize its structure, strengthen the protection of urban species diversity, so as to give full play the ecological service function of forest city.
