  1. 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。
  2. A preliminary study on the species composition, ecological characteristics and present distribution of vegetations in mengyang area, the largest part of xishuangbanna nature reserve, shows that there are 7 vegetation types, 15 formations, 24 community types in this area. the vegetation map was made by using gis software ( arc / info ), and the area and distribution pattern of each community was obtained. the subtropical monsoon evergreen broad leaved forest occupies the largest part, with an area of 41. 26 % of the whole, and the tropical rain forest occupies less than 10 % of the whole area. according to the topography, altitude, climate characters and present distribution of the vegetation, and based on the landscape type map, an original vegetation map under natural conditions was obtained, which could provid a theory for the vegetation restoration, especially for the tropical rain forest and its habitat, and for the development of the nature reserve

    對西雙版納勐養自然保護區植被的類型進行了劃分,包括人工和自然群落,共有7個大類、 15個群系、 24個群落類型分佈.對每個類型的主要組成種類、生態特徵和分佈現狀進行了初步研究.利用地理信息系統軟體制取植被圖並獲得了各種植被類型的分佈面積和分佈格局特徵,這一地區亞熱帶季風常綠闊葉林的分佈面積和所佔比例最大,達總面積的41 . 26 % ;而熱帶雨林面積不超過總面積的10 % .依據地形、海拔、氣候和現狀植被分佈的規律,在獲得景觀類型圖的基礎上,得到了可以反映這一地區在完全自然條件下植被可能分佈的狀況的還原植被圖,為保護區的發展和植被的恢復提供了理論依據。
  3. ( 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。
