黄河三角洲海平面上升风险评估及其对策研究

基于GIS技术,利用黄河三角洲SRTM(Shuttle Radar Topography Mission)卫星的DEM数字高程数据,Landsat影像和风险评估模型,制作相应专题图,并进行海平面上升风险评估。随着海平面上升,黄河三角洲的风险值和风险等级都随之增大,黄河口镇和仙河镇是最危险的乡镇。考虑抗灾能力后,黄河三角洲的海平面上升风险度降低,说明海岸防护是十分重要的。最后参考黄河三角洲海平面风险评估结果,提出黄河三角洲海平面上升的防灾对策与措施。

Seasonal and intraseasonal variations of the surface Taiwan Warm Current

To study seasonal and intraseasonal variations of the Taiwan Warm Current (TWC) in detail Rotated Empirical Orthogonal Function (REOF) and Extended Associate Pattern Analysis (EAPA) are jointly adopted with daily sea surface salinity (SSS), sea surface temperature (SST) and sea surface height (SSH) datasets covering 1126 days from American Navy Experimental Real-Time East Asian Seas Ocean Nowcast System in the present paper. Results show that the first and second REOFs of SST in the southern East China Sea (SECS) account for 50.8% and 39.8% of the total variance. The surface TWC contains persistent (multi-year mean), seasonal and intraseasonal components. The persistent one mainly inosculates with the Kuroshio but the seasonal and intraseasonal ones are usually active only on the continental shelf. Its persistent component is produced by inertial flow of the Kuroshio, however its seasonal and intraseasonal ones seems coming from seasonal and intraseasonal oscillations of monsoon force. The seasonal one reaches its maximum in late summer,lasting about four months and the intraseasonal one takes place at any seasons, lasting more than 40 days.
