During the course of the research, the criterions of the interpolation effect are mean error ( me ), mean absolute error ( mae ), root mean squared interpolation error ( rmse ) and the difference of mean square deviation between the measured and the estimated surface air temperature. the conclusions are as follows : ( 1 ) by contrasting the gaussian weighted model associated with the error modification with the gaussian weighted model, the error modification is proved to considerably ameliorate the precision of spatial interpolation ; ( 2 ) on the base of the gaussian weighted model, taking altitudinal effect into account can reflect the trend in which temperature changes according to the topographic altitude and may ameliorate the precision of spatial interpolation correspondingly and apparently, which indicates that topographical effect on the preciseness of spatial interpolation can not be disregarded in terms of the region with complicated topography ; ( 3 ) the map of daily surface air temperature distribution, using the modified gaussian weighted model a and b, can accurately reflect the temperature - changing - with - topographical - altitude trend. among them, the better is the model a, whose me is below 0. 03 ?
在此過程中，採用平均誤差（ me ） ，平均絕對誤差（ mae ） ，插值平均誤差平方的平方根（ rootmeansquaredinterpolationerror ，簡稱rmsie ） ，插值前後測站要素值的均方差（ meansquaredeviation ，簡稱msd ）差值作為判定插值效果的標準，得出如下結論：通過高斯權重法與結合逐步訂正的高斯權重法的對比，說明結合逐步訂正方案的高斯權重法可大大提高地面日氣溫的插值精度；在高斯權重法中加入海拔影響項可以反映出溫度隨地形高度的變化趨勢，同時也能較大地提高地面日氣溫的空間插值精度，說明在地形復雜的區域，地形影響在插值精度中是不可忽略的；對于高斯權重法的兩種改進方案得到的地面日氣溫分布圖都能很好地反映出表面大氣氣溫隨地形高度的變化趨勢。 -
Wutai is a rukai tribe stronghold. the name comes from the rukai language and means small village. very appropriately, the chinese characters used to write " wutai " mean fog terrace, as, being up at an altitude of 900 meters, every afternoon a fog settles in
霧臺是魯凱話，原意為小部落，因為地處海拔九百公尺的山區，每到午後便開始起霧，譯為霧臺倒也貼切，這里是魯凱族的大本營。 -
( c ) land natural productivity increase from 7843 kg / ( hm2 - a ) to 17335 kg / ( hm2 - a ) relate to altitude closely, and the mean rate of enhancing yield is 23. 53 percent in this region with annual enhancing - rate of 0. 64 percent in last 15 years. ( d ) there are many facters that have been influe ncing soil effective coefficient that ' s soil organic matter, total nitrogen, effective phosphine and soil texture in turn. in a word, attenuation cause of land productivity is the result of water and soil. ( e ) the forestland potential productivity change from 3986 kg / hm2 to 15034 kg / hm2, but it has a high distinction between southern aera and north area in yaan city. ( f ) the grassland potential productivity increase from 4085 kg / ( hm2 - a ) to 16973 kg / ( hm2 - a ), but it has a high classification of potential productivity, ( g ) ditribution map was formed of potential land productivity. ( h ) it could be act as decision support for agriculture development, national land planning and ecotop constructive, etc
5 、土地自然生產潛力水平的主要土壤限制因素為有機質、全氮，其次為速效磷和土壤質地；區域潛在生產力差異的制約因素，主要為土壤，次為水分，水、土兩項衰減合計為45 . 99 ，石棉、漢源兩縣水、土衰減達到60左右。 6 、林地潛力在3986 15034kg / hm ~ 2之間，高等級林地比重小，以大相嶺為界，北部的各縣林地生產力水平高，南部的兩縣林地生產力水平較低。 7 、天然草地生產潛力水平高，潛力在16973 4085kg / （ hm ~ 2 ? a ）之間，以高產的一、二、三級草地為主，且近10年來該比例變化不大。 -
The low re k - model in software phoenics3. 3 were applied to simulating indoor air temperature field in this two kinds of heating room contrastively. it shown that temperature gradient at human altitude in floor heating room is lower 3 ~ 4 c than radiator heating room, temperature adjacent out wall and out window near by radiator is higher 6 ~ 7 c than mean indoor temperature, temperature different of room top with mean indoor temperature in top floor radiator heating room is higher 1 ~ 2 c and thickness is 0. 3 ~ 0. 5m thicker than floor heating room
