如何利用有限的样本数据来获得更为准确的土壤属性空间分布信息是土壤学研究的热点问题之一。利用福建省龙海市采集的1 133个耕地土壤样品,设计了结合地貌类型、土壤类型和土地利用类型等信息的5种克里格插值模型,研究县级尺度上土壤有机碳空间预测优化插值模型及其与样点密度的关系。结果表明:设计的5种插值模型预测精度均高于普通克里格法,但不同样点密度对插值结果影响较大。按0.5km×0.5km及以上的格网密度进行样点布设,采用土地利用现状类型结合土壤类型信息的普通克里格法(KDLTR)插值结果误差较小;按2km×2km的格网密度布设调查样点时,采用土壤类型信息的普通克里格法(KTR)插值结果误差较小;当格网大于4km×4km时,由于样点数少,各种模型的结果相差不大,可直接采用普通克里格法(KYJZ)进行插值。

设计不同氮、磷供应量和不同施肥深度，对小麦／大豆间套农田土壤水分时空分布进行了研究。试验得出：间套农田土壤含水量由于受灌溉的调节表现出明显的时间变异性和分布非均衡性，但不同土层土壤含水量也表现出明显的层次性，即从上到下土壤含水量变异系数呈幂函数递减趋势。两种作物共生期间，小麦处于竞争优势位，其行间水分消耗较多，而小麦收获以后，大豆行间土壤含水量下降更甚，间套作农田土壤含水量不同时段表现出的这种水平变化特征，有利于ＷＵＥ的提高。供磷使０～６０ｃｍ土层土壤含水量下降了３．８％～１２．６％，又使表层土壤含水量提高了５．８％～１０４．９％，肥料深施和合理的Ｎ、Ｐ配施可促进间套作物地上冠生长，增加地面覆盖度，减轻棵间蒸发，提高土壤表层含水量。同时，促根效应也使深层水分不断补充到上层，促进根系、养分、水分的三位一体，达到三元协调、水肥耦合的效果。

Turboprop engine has the advantages of high efficiency and high thrust, but it has not been widely used in the civil field because of the noise excited by the low speed propellers. Propeller synchrophasing control is an active noise control method without increasing the weight of the airframe, which can attenuate the noise level in the cabin by controlling the relative phase among multiple propellers. It is generally accepted that altitude and airspeed have a great influence on the noise reduction effect of propeller synchrophasing, but there is no theoretical research about how these two factors affect the noise level. Therefore, flight experiment is considered to be a credible way. However, flight experiments of propeller synchrophasing control in turboprop aircraft have been accomplished in few countries due to enormous cost and inconvenience. An experimental platform of synchrophasing control based on a two-propeller small unmanned air vehicle(UAV) is proposed which can carry out the flight experiment research in a low-cost way. The phase angle sensor, the FOC-based scheme of motor driving, the all-slave synchrophasing control and the coordination between speed and phase difference control are presented in the UAV platform to meet its synchrophasing control precision requirement, experimental results prove that all of them can significantly enhance the performance of synchrophasing control. Noise characteristics of propellers are studied in the flight experiments, the noise predicted by the noise model is highly consistent with the actual measured noise, which verifies that the noise characteristics of small UAV accord with propeller signature theory. Based on the noise model, propeller synchrophasing has a steady effect to minimizing noise in the UAV platform. These show that the UAV platform is a feasible solution for propeller synchrophasing research.
