giss 中文意思是什麼

Projections based on the predictions of gcms, including cccm, giss, cgcm2 and hadcm3 models, provided information on future climatic conditions, and then water temperature in the future can be predicted accordingly

在研究中利用cccm 、 giss 、 cgcm2以及hadcm3等大氣環流模式提供未來氣候變遷之下的氣候資料，進行未來氣候條件下的水溫模擬。

Main technic of giss webgiso thus function modules architecture and network topological structure are confirmed webgis system implements the basic function of electronical map, such as map zoonu pan, and the abundant query of geograph and database by using maplnfo mapxtreme for java as map server and jsp., java technico this system also can implement the routing of linesx analysing of buffer and so on0 this paper advances storage model of roads and pipelines topology data, efficiently solves the maintenace problem of network topology data of webgis and implements the shortest path algorathm based on webgis by improving it0 the system has better opening by suppling database interface of map ? the system has perfect on - line help and user forum and favorable interfaces and implementation of this system makes fundament for the further research of webgiso

In the second section, three ( 2 co2 ) scenarios only considering climate change alone ( c scenario ) were generated first, using outputs of the giss, gfdl and ukmo gcms, combined with the baseline. then, climate change scenarios including change in climate variability ( c + v scenario ) were produced, based on 3 hypotheses and the weather generator ( wgen ) in dssat. finally, the ceres - wheat model was run under both the ( c + v ) scenarios and the baseline, and the combined effects of climate change and its variability with doubled co2 on whiter wheat production in the studied region were assessed, based on the results simulated comparison

在上述第2部分，首先利用baseline和國際上通用的3種大氣環流模型（ gcms ）即giss 、 gfdl和ukmo的有關網格點值，生成了研究區域3種不考慮氣候變率變化的（ 2 co _ 2 ）氣候變化情景（以下簡稱c情景） ；然後，提出了未來氣候變率可能變化的3種假設，並應用dssat （農業技術轉化決策支持系統）中的wgen （隨機天氣發生器） ，分別生成了研究區域（ 2 co _ 2 ）條件下兼顧氣候及其變率的氣候變化情景（以下簡稱c + v情景） ；再后，在上述（ c + v ）情景下分別運行ceres - wheat （作物-環境資源綜合系統-小麥） ，還考慮了大氣co _ 2濃度的直接影響，並與baseline條件下ceres - wheat的模擬值進行比較，在此基礎上評價了（ 2 co _ 2 ）條件下氣候及其變率變化對研究區域冬小麥生產的影響。

In the third section, the emphasis was put on evaluation of the gradual effects of climate change in future 50 years. all the three sections drew an outline of global climate change affecting the whiter wheat production at present and in future in the studied region. in the third section, the gradual climate change scenarios considering both climate and its variability in future 50 years ( i. e., 2010, 2030 and 2050 ) were generated, using outputs of the giss transient run and the baseline, adopting the same method described in the second section mentioned above

第3部分，選擇gisstransientrun （氣候漸變模型）的有關網格點值，採用上述第2部分同樣的方法，生成了研究區域未來50年內（即2010年、 2030年和2050年）兼顧氣候及其變率變化的氣候漸變情景，並結合ceres - wheat的模擬結果，分析了氣候及其變率變化對研究區域冬小麥生產的階段性影響，並應用gis軟體，對各代表性樣點的有關模擬結果進行了圖像顯示。

In this paper we simulate with the use of giss ocean - atmosphere model adopting land - ocean distribution of the present and 14mab. p

時設計的海陸分佈作為邊界條件，分別進行了數值模擬。

Comprehensive studying the key technology about geographical information server system. ( giss ) geographical information server system. ( giss ) is a large system project, including gis ( geographical information system )

地理信息服務體系，是一個涉及到gis 、 internet網路、數據庫等眾多領域的系統工程，其所涉及的技術很多。

2, designing an practical giss based on the research of studying in this paper, we are using the mode of client / server. this mode include some parts. first, server can manage the data and non - graphical operation, for instance, data personality and analysis

本文採用的是client / server模式。該模式的主要功能分配為：服務器端主要用來處理用戶的非圖形操作和數據處理，如數據定製、查詢和分析。
