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。

The results showed:Under the same fertilizer consumption,covered with straw and covered with film can increase the chlorophyll content and total leer area duration of the maize,can improve leaf nitrate reeducates activity,Photosynthesis and roots vigor,and the nitrate reeducates activity,the chlorophyll content and the roots vigor present positive correlation with yield. Meanwhile,average dry matter accumulation of straw-covered increased 7.1% than this of no-ploughed,yield increased 15.3%.The average dry matter accumulation of film-covered increased 20.1% than which of no-ploughed and 12.1% than which of plough and covered with straws.And yield increased 26.8% and 10.1%,notable differences.

结果表明：在相同的肥料用量条件下，秸秆覆盖和薄膜覆膜对玉米生长发育具有良好的促进作用，能显著增加玉米叶片叶绿素含量和光合势，增强叶片硝酸还原酶活性和根系活力，同时玉米叶片硝酸还原酶活性、叶绿素含量、根系活力等与最终籽粒产量呈正相关；秸秆覆盖比免耕全生育期平均单株干物质积累量增加7.1%，籽粒产量增加15.3%，薄膜覆膜分别比免耕和翻耕残茬覆盖全生育期平均单株干物质积累量增加20.1%和12.1%，最终籽粒产量增加26.8%和10.1%，差异显著。

This article has carried on the analysis to the signal divulging question. Through to in the edge field intensity computation and the building structure, the article proposed avoids method which reveals. Analyzed simultaneously the possible influence to depot rate lost call of base station produces and proposed the solution method. From three different aspects of falls in the speech, the article proposed influence of in room cover to the base depot voice dropout rate, and induced three kinds of reasons as well as the questions which should be paid attention to in the engineering design.
