| 摘要: |
| 基于遥感和GIS工具，利用深圳市范围内的遥感影像进行地表温度反演，并通过数字化方法选取公园斑块，研究公园、公园内绿地、公园内水体与公园内部及其周边地区平均温度的关系。研究发现：公园周长面积比、植被覆盖度、绿地面积是影响公园内部温度的主要因子，公园水体面积是影响公园周边温度的重要因子，公园面积和公园周长对公园内部和周边温度影响较小。同时，基于深圳40个公园的热岛效应消减特征提出了周边效能最大型、自身效能最大型和内外效能平衡型3种公园类型和各自特征，对未来深圳建成区的城市公园规划建设具有一定的借鉴意义。 |

| Abstract: |
| Taking Shenzhen as an example, this paper conducts land surface temperature retrieval with the help of RS and GIS tools as well as the remote-sensing image within Shenzhen. Selecting a plague of the park guided by manual digitizing, this paper investigates the influence of the area, circumference, shape, vegetation coverage and water coverage of the park upon the average temperature of the internal and surrounding of the park. According to the result, the shape index and vegetation coverage of the park are two chief factors influencing the internal temperature of the park, the water coverage is the key factor to its surrounding temperature, while the area or circumference hardly plays a role in the park's temperature change. Meanwhile, based on the reduction of heat island effect related to the shape index, vegetation coverage and waters, three park types are concluded: the most efficient regionally, the most self-efficient and balanced. Then an empirical analysis of heat island effect reduction is made on Xiangmi Lake Park, Lianhua Mount Park and Central Park, thus offering reference experience for the planning and construction of parks in Shenzhen. |
