Remote sensing of the urban heat island and its changes in Xiamen City of SE China

World-wide urbanization has significantly modified the landscape, which has important climatic implications across all scales due to the simultaneous removal of natural land cover and introduction of urban materials. This resulted in a phenomenon known as an urban heat island(UHI). A study on the UHI in Xiamen of China was carried out using remote sensing technology. Satellite thermal infrared images were used to determine surface radiant temperatures. Thermal remote sensing data were obtained from band 6 of two Landsat TM/ETM^ images of 1989 and 2000 to observe the UHI changes over l l-year period. The thermal infrared bands were processed through several image enhancement technologies. This generated two 3-dimension-perspective images of Xiamen‘s urban heat island in 1989 and 2000, respectively, and revealed heat characteristics and spatial distribution features of the UHI. To find out the change of the UHI between 1989 and 2000, the two thermal images were first normalized and scaled to seven grades to reduce seasonal difference and then overlaid to produce a difference image by subtracting corresponding pixels. The difference image showed an evident development of the urban heat island in the 11 years. This change was due largely to the urban expansion with a consequent alteration in the ratio of sensible heat flux to latent heat flux. To quantitatively compare UHI, an index called Urban-Heat-Island Ratio Index(URI) was created. It can reveal the intensity of the UHI within the urban area. The calculation of the index was based on the ratio of UHI area to urban area. The greater the index, the more intense the UHI was. The calculation of the index for the Xiamen City indicated that the ratio of UHI area to urban area in 2000 was less than that in 1989. High temperatures in several areas in 1989 were reduced or just disappeared, such as those in old downtown area and Gulangyu lsland. For the potential mitigation of the UHI in Xiamen, a long-term heat island reduction strategy of planting shade trees and using light-colored, highly reflective roof and paving materials should be included in the plans of the city planers, environmental managers and other decision-makers to improve the overall urban environment in the future.

厦门市大气污染物及酸雨现状与发展趋势

通过对厦门主要大气河南省的及降水状况进行了近十年连续观测及研究，厦门大气污染物ＳＯ２、ＮＯＸ、ＴＳＰ污染水平不高，但ＮＯＸ浓度的上升必须引起重视：Ｏ３及Ｈ２Ｏ２含量较高，大气氧化气氛较强，大气中ＮＨ３浓度较低，这是厦门酸雨产生的重要原因，且降水酸化有逐年加重的趋势。     

浅谈厦门市综合应急救援队伍建设的实践与思考

1引言厦门是福建省自然灾害较为严重的区域之一,灾种多、灾期长,发生频率高、受灾损失重。灾害事故类型主要包括以暴雨洪涝、台风气旋为代表的气象水文灾害和以滑坡、崩塌、泥石流为代表的地质灾害。厦门还处在地震断裂带上,已经有400多年没有发生地震,一旦发生地震,极有可能引发海啸等自然灾害。此外,厦

台北与厦门城市固体废弃物管理体系比较研究

城市固体废弃物的综合处置与管理是城市可持续发展的核心问题之一。选取海峡两岸的厦门市和台北市,论述和比较2个城市固体废弃物管理的历史沿革、发展概况、管理框架、收集运输系统、经济手段及最终处置方法等,发现台北在城市固体废弃物管理方面已达国际领先水平,而厦门正处于台北曾经历过的理论探索、系统完善阶段。对比2个城市的管理经验,可以为厦门及中国其它城市提供重要借鉴。最后在相关数据分析的基础上,提出了厦门城市固体废弃物管理的政策建议。
