Taking jiuyuan as a sample region , this part gives a brief account of natural condition and situation of social economy 選擇包頭市九原區(qū)作為研究樣區(qū),確立具體研究內(nèi)容和目的,概述了九原區(qū)自然條件和社會經(jīng)濟狀況。
It is different from concentric mosaics as follows . the sampling region of border panoramas can be arbitrary convex region , such as rectangle , square , triangle , circle or any other shape . and its sampling manner is sampling cylindrical panorama at border of the region point by point 它與同心拼圖( concentricmosaics )的不同之處在于,采樣區(qū)域可以是任意的凸區(qū)域,比如矩形、三角形、圓或者其它隨意的形狀,采樣方式是在區(qū)域的邊界上逐點采樣柱面全景圖。
Taking jiuyuan , baotou as the sample region , the administrative unit , county and town , as the statistic objects , the paper analyzes the driving factors of change of land - use from the time and space dynamic change of use of land resources . then , the paper establishes a forecast modal of change of jiuyuan ' s land - use , which can provide the regional land organization with the decision basis of planning and management of land - use and sustainable use of regional land resources 在地理信息系統(tǒng)技術(shù)的支持下,以鄉(xiāng)、鎮(zhèn)(蘇木)級行政單元為統(tǒng)計單元,從土地利用時空動態(tài)變?nèi)胧郑瑧?yīng)用數(shù)理統(tǒng)計方法分析土地利用變化驅(qū)動因素,并建立預(yù)測模型,最后指出九原區(qū)土地可持續(xù)利用的對策及措施,為區(qū)域各級部門進行土地利用規(guī)劃與管理以及土地持續(xù)利用提供決策依據(jù)。
In the second part ( including chapter 4 ) , this paper applies gray level coocurrence matrix and image texture feature quantities to evaluate eliminate effect through computing the same sampling region selected . the results show that the three methods can eliminate solar eclipse impact on the satellite vis imagery so that the topography , cloud system texture and ocean current are distinct and differentiable and it is good for analyzing the clouds and weather systems on the cloud image . comparing the three methods , the improved geometry - model method is the most effective 研究結(jié)果表明:原幾何模型法、改進的幾何模型法和數(shù)學(xué)函數(shù)模型法基本都能消除日食對云圖的影響,經(jīng)過訂正處理后,各種特征紋理變細(xì),結(jié)構(gòu)變清晰,信息增加,有利于云圖上云和天氣系統(tǒng)的識別和分析;三種方法的比較認(rèn)為,改進的幾何模型法訂正效果最好,原幾何模型法的效果較差,數(shù)學(xué)函數(shù)模型法更加快速、簡便,但其涉及的主觀因素較多。
In this paper , taking the loess plateau of china as a sample region , all the factors which are related to the soil and water loss are analyzed ; the assessment indices ( model parameters ) are defined ; and the data with different origins are integrated using gis ; finally , the soil loss model for this region is set up 本文以黃土高原地區(qū)為例,結(jié)合影響水土流失的各個因子,分析了該區(qū)的自然特徵,確定了進行區(qū)域水土流失評價的各項指標(biāo)(模型參數(shù)) ,并運用gis ,集成了多種來源、多種比尺和多種類型的數(shù)據(jù),建立了該區(qū)的水土流失宏觀定量評價模型。
