利用回歸方程對今後的植被變化情況進行了模擬預測,其結果具有一定的參考價值;南京氣象學院博士學位論文8 .將馬爾科夫過程成功地應用於中國西部干早區的植被變化分析當中,指出,植被的轉移變化不是一重馬爾科夫過程,而是一個多重的馬爾科夫過程;而且是一個步長較長的馬爾科夫過程; 9 .證明在8klll尺度下,馬爾科夫過程不能使用兩期的土地利用變化來預測土地利用的發展趨勢,無論這兩期的時間是連續的還是有一定時間間隔的;通過各類植被的面積變化、空間變化及馬爾科夫過程分析認為:中國西部乾旱區在平原區整體上荒漠面積減少,綠洲面積增加,綠洲的面積擴大主要表現在原有綠洲的擴大。Today, a lot of application systems combine with gis, such as diagnosis expert system including the diagnosis the varies aspects of society, economy, and agriculture ; forecast expert system including the forecast of weather, hydrometeorology, population, geography, economy, military affairs, politics, etc ; decision supporting system including the aspect of engineering design, programming, consultation, management etc. the traditional gis system can only use mathematic method to describe and explain the confirmed programs but the power of making space decision and solving the uncertain programs are very weakly
現在許多應用系統所涉及到的問題都與地理信息有關,例如:診斷專家系統中的社會、農業、經濟等方面的各種診斷和排錯系統;預測專家系統中的氣象、水文、人口、地理、經濟、軍事以及政治等方面的預測分析系統;工程設計、規劃、咨詢和管理決策等方面的專家系統,都離不開地理信息的支持。但是,傳統的地理信息系統( gis )解決問題的方法和模式基本上都是以數學方法為基礎建立的,所能解決的有關地理問題也主要是那些能夠用數學方法描述和解釋的具有確定性解的問題,在解決空間規劃決策中有很大的不足。With reference to calculation methods of solar radiation within domestic and abroad literature and with the help of our country ' s dem ( with its resolution is 1 km x 1 km ), we build a new model for potential solar radiation calculation combining with pci geomatica ' s platform. in the calculation, hypothesis is that insofar one clear day in more than one year as the biggest value of solar radiation of one day in many years is defined as potential value of daily global solar radiation, we also consider the infection of the slope, aspect and its geometry relations affect on solar radiation. we calculate potential solar radiation which maybe useful for research the distribution of solar energy and build large - scale grid database of our country ' s solar radiation
