降水

The water quality of rainfall, through-fall, stem-flow, litter through and runoff in Pinus koraiensis plantations of the eastern mountainous regions of Heilongjiang Province were studied. Water quality indexes, pH, DO, TURB, TDS, K, Na, Ca, Mg, Cu, Zn, Mn and Fe were also analyzed.

对黑龙江省东部山地红松人工林生态系统的大气降水、穿透水、树千径流、枯透水和地表径流中的pH值、溶解氧、浊度、总溶解固体、K、Na、Ca、Mg、Cu、Zn、Mn和Fe等水质指标进行了检测。

Induced precursory anomalies have 7 main features,i.e.diversity of types,the nonlinearity correlating with the change of rain and groudwater,the periodicity and seasonal feature of occurrence,hierarchical feature of variation,tussocky feature in temporal distribution,broad area in...

诱发前兆异常具有 7个主要的特征，即种类的多样性、与降水及地下水变化关系的非线性、发生的周期性和季节性、变化的层次性、时间分布的成丛性、空间分布的大区域性以及多种手段异常变化的时空关联性等。

From the analysis's quantitative indices of infrared wavelength split window TBB about typhonic rainfall were found.

TBB 与降水量的对应关系、TBB与各量级降水量的累积频率分布等进行处理与分析，得出台风降水的红外分裂窗TBB定量估计指标。

It shows that the Taiwan topography influence on the movement and the central air pressure is salience. The topography force influence on the typhonic central intensity and unsymmertrical structure is very evident. The Taiwan topography is the primary reason for the low pressure in the windward mountain and high pressure in the leeward mountain. The topography is the primary reason for the peripheral precipitation reinfor4ce of the typhoon.

试验结果表明：台湾岛地形对台风&泰利&的移动路径和中心气压的影响不显著；地形的强迫作用对台风涡度场的中心强度和非对称结构有明显的影响；台湾岛地形是形成迎风坡诱生低压和背风坡诱生高压的主要因子；地形是台风外围降水加强的主要原因。

The first grade is characterized by unchange after rain in discharge, pH, EC and T.

雨季pH在降水后出现暂时的降低，电导率和水温出现暂时的升高。

The evapotranspiration was 403mm when water use efficiency was highest. 7.During middling rainfall years, the irrigation was 190mm in entire growing period of wint

禹城地区冬小麦在中等降水年份军全生育期适宜的灌水量为 19m 左右，灌三水，宜重点保证返青拔节和孕穗灌浆期间的水分需求。

The soil water regionalization of Hebei Province should be based on the soil zonality, harmonize with the agricultural regionalization and keep the administration districts in integrity.

无论是灌溉水，还是天然降水，都要转化为土壤水后才能被作物根系吸收，它是农业和生态环境中各种作物和植被赖以生存的基础[1]。

By using muti-variable mean generation f uncti on of the predictand and its predictor, the mean generation function is orthogon alized by means of the Gram-Schmidt s method.

用预报量与多变量预报因子的均值生成函数，通过 Gram- Schmidt正交化使均值生成函数彼此正交，同时利用双评分准则确定入选预报模型的均生函数个数，最后建立山西省季节降水的预报模型。

Therefore, doing research of the nutrient balance in the loessplateau has its practical signification. Using the long-term rotation and fertilization experiment that disposed in dry land on theloess plateau, the paper has studied nutrients in rainfall import to farmland ecosystem andAmmonia volatilization losses and nutrients disbursal of crop, also estimated the balance ofnutrients in farmland soil.

本文利用设在黄土高原旱地上的长期轮作与施肥试验，主要研究了黄土高原农田生态系统养分的降水带入、作物地上部分的氨挥发损失和作物的养分支出，并进行了 N、P、K 养分平衡评价。
