( 2 ) when 37ghz and 94ghz radars detect clouds, the difference between the atmosphere and cloud attenuation and the large variety of radar reflectivity conduce the intension of the radar backscatter signals change. ( 3 ) for the thin cloud layer and low water content of cloud, 37 - ghz radar backscatter signals are not as good as 94 - ghz radar, that is to say that the 94ghz radar has better capability in thin clouds detection
本工作得出如下結論: ( 1 )大氣氣體的微波吸收在測雲波段產生明顯的衰減,其中水汽衰減效應變化很大;即將上天的空間94ghz測雲雷達必須有水汽衰減訂正方案; ( 2 ) 37ghz和94ghz雷達測雲,由於大氣和雲衰減不同和雷達反射率的很大差異,導致雷達回波信號強弱不同; ( 3 )對雲層較薄、含水量較少的雲,在不計雷達參數的情況下, 37ghz雷達回波信號不如94ghz測雲雷達,也就是說94ghz對薄雲有更強的探測能力;對雲層較厚、含水量大的雲,由於強衰減的作用, 94ghz雷達回波信號小於37ghz雷達; ( 4 )從大氣衰減的不利因素方面考慮,空間94ghz雷達測高層薄雲的效果最好;測低層薄雲時需要考慮氣體衰減訂正;因濃厚雲的強衰減作用,探測其中下部的能力大大減弱,不僅要進行衰減訂正,而且要藉助其他信息來反演整個雲層的含水量垂直分佈; ( 5 )為了獲得從極薄到極濃厚雲的垂直分佈探測能力,未來測雲雷達系統最好採用雙波長甚至三波長(如94 、 37和13ghz ) 。On the loess plateau, water is the main limiting factors for vegetation growth. root distribution characters have special ecological meaning as it reflected the utilizations of trees to the environments. even - aged stands of robinia pseudoacacia on slope lands facing south and north were selected as sampling plots for root distribution investigation. investigatiing results showed that indicated that on all sites, root biomass decreased with depth, and the distribution depth of fine root was deeper than that of coarser root. the results of variance analysis indicated that there were great differences in root biomass among different diameter classes, and coarser root was the main sources of variance, and the root biomass, especially fine root ( < 3mm ) biomass on northern exposition sites was bigger than that on southern exposition sites. analysis of the vertical root distribution parameters, root extinction coefficient, indicated that the value of on northern exposition was more than 0. 982, while the value of on southern exposition was less than 0. 982, which indicated that the vertical root distribution depth of robinia pseudoacacia on southern exposition was deeper than that on southern exposition. and the distribution depth of fine roots ( < 1mm ) was deeper than that of thicker roots ( < 3mm ), which was in favor of the uptake of water and nutrients from deeper layers, helped the trees to adapt the arid environment, and promoted the growth of the upper parts of the tree
在中國西北黃土高原地區,水分是樹木生長發育的主要限制因子.根系分佈特徵由於反映了樹木對環境條件的利用程度而具有更加特殊的生態意義.本研究選擇陽坡和陰坡不同立地上年齡一致的刺槐林調查了根系分佈特徵.根系垂直分佈特徵的調查結果表明,在所有立地上,根系生物量隨著深度的增加而降低,其中細根的分佈深度大於粗根的分佈深度.方差分析結果表明:不同立地上不同徑級根系的分佈特徵也有明顯的差別,粗根是差異存在的主要原因,陰坡立地上的根系生物量,特別是細根生物量大於陽坡立地上的.對根系消弱系數的分析結果表明,陰坡立地上的根系消弱系數大於0 . 982 ,而陽坡立地上的根系消弱系數小於0 . 982 ,說明陰坡立地上刺槐根系的生物量在深層土壤中的分佈相對量更大一些.其中細根的根系消弱系數大於粗根的,這種根系分佈特徵有利於根系對深層土壤水分養分的吸收利用,進而促進樹木地上部分的生長發育.圖3表3參15Abstract : on the loess plateau, water is the main limiting factors for vegetation growth. root distribution characters have special ecological meaning as it reflected the utilizations of trees to the environments. even - aged stands of robinia pseudoacacia on slope lands facing south and north were selected as sampling plots for root distribution investigation. investigatiing results showed that indicated that on all sites, root biomass decreased with depth, and the distribution depth of fine root was deeper than that of coarser root. the results of variance analysis indicated that there were great differences in root biomass among different diameter classes, and coarser root was the main sources of variance, and the root biomass, especially fine root ( < 3mm ) biomass on northern exposition sites was bigger than that on southern exposition sites. analysis of the vertical root distribution parameters, root extinction coefficient, indicated that the value of on northern exposition was more than 0. 982, while the value of on southern exposition was less than 0. 982, which indicated that the vertical root distribution depth of robinia pseudoacacia on southern exposition was deeper than that on southern exposition. and the distribution depth of fine roots ( < 1mm ) was deeper than that of thicker roots ( < 3mm ), which was in favor of the uptake of water and nutrients from deeper layers, helped the trees to adapt the arid environment, and promoted the growth of the upper parts of the tree
