项目摘要

Monitoring coastal environment, particularly landscape and vegetation on coasts and beaches, is considered to be important because they change rapidly and drastically due to the natural cycle and artificial pressures. Several monitoring tools for the coastal zone environment have been developed to date. However, most of them require heavy instrument and are often lacks cost effectiveness. In order to achieve cheaper and handy spatial monitoring, we developed video and camera recoding devices attached to a motor-powered paraglider. It can provide clear and sharp photographic data from very low to relatively high altitude. The resolution of the data is down to 5cm depending on its altitude and recording device. The experiment and development of monitoring equipment were carried out in 1999 and 2000 to test its efficiency and effectiveness. The results showed that the photographic data could be utilized for image analysis, for example measuring changes in coastal vegetation, monitoring artificial alternation on foreshore and counting litters on beaches. It also demonstrates cost effectiveness because motor-powered paraglider flights do not cost very much in comparison to ordinary aerial photograph by helicopters and airplanes. This monitoring method can be used for NPO and NGO to track changes in coastal environment regularly with relatively lower cost. Furthermore, the photos taken by this device can be amalgamated and attached to the map by using Arc view GIS software based on the positioning data obtained from a camera or VTR that is equipped with DGPS (differential global positioning system).

监测海岸环境，特别是海岸和海滩上的景观和植被，被认为是重要的，因为它们由于自然循环和人为压力而迅速而剧烈地变化。迄今为止，已经开发了几种沿海地区环境监测工具。然而，它们大多需要笨重的仪器，而且往往缺乏成本效益。为了实现更便宜和方便的空间监控，我们开发了视频和相机记录设备，连接到一个电动滑翔伞上。它可以从非常低的高度到相对较高的高度提供清晰锐利的摄影数据。根据其高度和记录设备的不同，数据的分辨率可降至5厘米。在1999年和2000年进行了监测设备的试验和开发，以检验其效率和有效性。结果表明，这些影像资料可用于影像分析，例如测量海岸植被变化、监测前滩人工改变和统计海滩上的垃圾。它还证明了成本效益，因为与直升机和飞机的普通航拍相比，电动滑翔伞飞行的成本并不高。这种监测方法可以用于NPO和NGO定期跟踪沿海环境的变化，成本相对较低。此外，该设备所拍摄的照片，可以根据配备DGPS（差分全球定位系统）的相机或VTR所获得的定位数据，利用Arc view GIS软件进行合并并附加到地图上。
