By the study of the relationship between vegetation and spatial characteristics of UHI, the mainly spatial characteristics of UHI has been analyzed and it was:(1) The terrain of the suburbs is higher than the urban region, the gradient of the terrain height is small, and this geomorphological featrue is conducive to assemble of the heat, the UHI phenomenon of Changsha is obvious especially in the summer night;(2) The UHI distribution is similar to the outline of the urban construction. The LST of urban is 3-5℃ higher than the flat low areas close around the city, and 6-8℃ higher than further areas. The region which has the most obvious UHI phenomenon is the region surrounded by the second city ring road, and the UHI phenomenon gradually weakened from the city centre to suburb;(3) The impact of geomorphological character to UHI is notable, the relationship between vegetation index and UHI is Anti-related, it was indicated that the improvement of the vegetational status is very important to the elimination of UHI phenomenon, the implementation of the urban green land planning can reduce UHI effect.

通过分析长沙城市地区的土地覆盖、植被绿地状况与热岛空间分布状况的关系，揭示出研究区域UHI主要特征为：(1)从研究区域地表覆盖图发现，长沙市城区四周均有相对地势较高的山地，但地形梯度不大，接近四面环山的地貌特征，容易造成城区的热量聚集，有利于城市热岛效应的形成，使得长沙城区存在明显的热岛分布；(2)UHI分布与城市结构的轮廓相一致，长沙城区与地势相对平坦的近郊区的地表温度差异为3~5℃，与地势较高的周边远郊区的地表温度差异为6~8℃，长沙城区热岛效应与城市规划呈对应关系，热岛效应最显著的区域为二环线内，并从中心沿三环逐渐向郊区减弱；(3)地表覆盖类型对UHI的效应明显，长沙地区植被绿地状况与UHI呈现明显反相关分布，揭示出植被绿地对降低UHI具有重要的作用，大范围的绿地建设能有效降低UHI。

Although the accuracy in meterological forecast of tropical cyclones has been distinctly improved, it is still a difficult problem confronting masters and anti-typhoon team leaders of the companies how to steer clear of typhoon reasonably and safely in case that the actual resistance to typhoon is strong enough, the sea area wide enough, and the time permitting ; to avoid unreasonable deviation,anchoring for shelter, blindly rushing onto her path,being involved in storm area,even into the the center of typhoon; under the limitation of the condition of the sea area and time.how to take correct meassures to escape , such as navigating with wind or windward in bias angle, slowing down, anchoring, berthing alongside the warf, mooring to buoy,etc.

传统的解决办法是，将台风中心的预报位置和本船的船位点绘在《台风位置标示图》上，研究本船与台风的相对位置以及相互间动态的发展态势，考虑各种因素的影响并留有充分余地，在小比例尺海图上用几何相对运动标绘的方法作图绘算出本船应采取的避台航向。本文所讨论的就是为迅速和较为精确地解决以上点绘和相对运动标绘的问题，在考虑了各种因素的影响并留有充分余地的情况下，在全方位范围内搜索安全航向，对本船与台风的相对位置以及两者之间的动态发展态势作出预报，并给出船长最关心的、对其作出避台决策至关重要的一组数据和直观图形，帮助使用者及早制订科学合理的避抗预案，及时果断地采取正确有效的避抗措施，解决避台决策的实际问题而设计的一个计算机标绘系统。

For the first stage, with the help of adjusting curriculum setting, castigating teaching outlines and using suitable modern teaching technology, it is expected to finish the regular teaching task of four years in a three-year period. As for the second stage, in order to improve the students knowledge structure and ability structure, measures should be taken to improve their professional practical ability. The method for achieving that purpose is to give the students intensified training for practical skills and technologydeveloping in the fields of typical production, equipments and craftwork task in the enterprises.
