| 8. | Heat fluxes estimated from radiative temperature by this model is more accurate than other regular corrective methods . two - layer model has been proposed for many years but was difficult to apply in remote sensing because component temperature were unavailable in traditional thermal sensors . a new airborne multi - angular thermal sensor system and retrieved soil and canopy temperatures were used to solve two - layer model , and the simulated heat fluxes show much better accuracy than the results from one - layer model especially above dry surfaces
双层模型虽然提出很多年了，但在应用中一直存在信息不足，求解困难的问题，本文用最新多角度热红外遥感数据? ? ? amtis系统反演的组分温度，首次实现了双层模型在遥感中的应用，结果表明，在输入参数精度相近的情况下，双层模型模拟的通量误差远小于单层模型，尤其在土壤干旱，表面温度较高的地表，双层模型的理论优势在计算中表现得更加突出。 |

干热河谷的土壤特征表现为土层浅薄、土壤结构差、土壤石质粗骨性强或表土紧实、土壤干旱等。虽然土壤有机质含量低、有效养分也较缺乏，但是土壤水分性质是植被生长恢复的关键制约因素。 |
| 10. | The result of experimentation on coupling effect of water and fertilizers on spring corn in the three gorges reservoir area indicate that water stresslead the effect low of highness and lai , and the most effect is made in shooting stage ; it has a significant positive correlation between the yield of corn and biomass , and hasn ' t none significant positive correlation between the yield of corn and the weight of roots ; the coupling effect of water and n is significant , but the coupling effect of water and k is not significant , the maximum yield of corn condition fitting - water and medium n , corn absorbs n has a threshold value during the growth , and using superfluous n is able to prick up soil drought and crop drought ; water is the leading factor which effects the yield of corn , next is n and k
摘要三峡库区春玉米盆栽水肥耦合试验研究结果表明，水分胁迫导致玉米株高和叶面积指数降低，以拔节期受到影响最大；玉米产量与生物量呈显著正相关关系，产量与根重无显著正相关关系；水氮耦合效应显著，适宜水分和中氮处理下玉米的产量最高，玉米生长发育对氮肥的吸收存在一定的阈值，过多施用氮肥会加剧土壤干旱和作物干旱，水和钾耦合效应对玉米产量影响不显著；水分是影响玉米产量的主导因素，其次是氮效应和钾效应。 |
