This paper proposes the indexes for the climatic division and suitability of tobacco growth in yunnan according to the regional climatic characteristics : heat resource as primary index while precipitation and sunshine duration as secondary indexes
摘要根據雲南烤煙氣候特點，提出了判別雲南烤煙氣候類型及其適宜性的指標：熱量為一級指標，降水和光照為二級指標。 -
The geographical point of soil phosphorus equilibrium refers to some quantitative characters of soil phosphorus system when its cycle becomes steady relatively in certain geographical, biological and climatic backgrounds. its index and seeking method are determined differently in different studies
土壤磷素地理平衡點指在特定的地理生物氣候背景下，土壤磷素系統循環達到相對穩定平衡時的量化指標的數量水平，它的指標選取和求取方法應根據研究目的需要來確定。 -
The high change of preci - pitation made spatio - temporal change of climatic productive potentialities bigger than that of photosynthesis and photo - temperature. the trend of water decreasing from south to north, from east to west in hebei, beijing, tianjin and shandong, from south to north in shanxi, shaanxi and henan made every index has the same trend almostly
降水年際變異較大，區域差異明顯，使得氣候生產力的時空變化大於光合和光溫生產力的時空變化，在中東部，水分由南向北、由東向西減少，中西部由南向北減少，使得各項指標的變化均有與此基本相應的變化趨勢。 -
Climatic mean map, it is further confirmed that it s a good approach to retrieve the equatorial zonal circulation by using the ir indicate ascending branch and wv indicate descending branch channels. the definition of the index of zonal circulation with the olr and fwv are presented and the 17 years mean annual and seasonal equatorial circulation are drawn. the climatic characteristics of the equatorial zonal circulation are analyzed in detail. consequently the fore results of the other observation are corrected
通過波耳茲曼公式換算得到的6 . 7m水汽輻射通量密度，以便於與olr比較與ncep再分析的500hpa的年氣候平均圖進行比較，分析其異同，進一步證明了用衛星觀測的紅外，水汽雙通道olr表示上升運動， fwv表示下沉運動去反演緯向垂直環流是一個極好的途徑。 -
The probability distributions of climatic elements are discussed. based on the characters of them, a multimode model is introduced and verified through the nonlinear fitting. the climate features of quasi - biennial oscillation of the stratospheric zonal wind over equator, the enso index, the surface pressure at reykjavik 21 90w 64 13n and swedish temperature, and the northern hemisphere tree ring all show that the multimode are universal in the climatic system
對氣候要素的概率分佈進行了討論，根據這些概率分佈的特點提出了多模態模型，並用非線性擬合的方法進行了驗證。對赤道平流層緯向風enso指數esi序列冰島reykjavik 21 . 90w ， 64 . 13n氣壓和瑞典溫度北半球樹木年輪等數據的分析表明：氣候系統中多模態現象具有普遍性。 -
The main conclusions include : 1 ) water use level and water use efficiency in the yellow river region have been much improved than before, but are still in a lower level ; 2 ) water use level and water use efficiency are quite different in the different sub - regions of the yellow river region ; 3 ) agricultural water use index is high in this region, the main reasons lie both on the special climatic conditions, and the underlying surface situation, and on the extensive cultivation in this region
結果表明：黃河區用水水平和用水效率較以往有較大提高，但仍然還比較低；流域內用水水平和用水效率不平衡；農業用水指標偏高，既與其特殊的氣候條件和下墊面因素有關，也與該區較為普遍的粗放灌溉方式有關。
