Contemporary artificial rainfall is artificial rainfall basically is principle of basis nature rainfall, launch activator from the ground through the plane is spread or using tall artillery piece, rocket, wait like silver iodide, dry ice, liquid nitrogen, drop cloud layer temperature thereby, form supersaturation lunt; to perhaps condense to the boardcast sowing in the cloud layer that contains supersaturation lunt nucleus, increase the ice crystal amount in the cloud, increase the amount of drip-drop and diameter then, raise cloud precipitation change rate, achieve the goal that raises precipitation of bureau ground nature thereby.

二、现代的人工降雨人工降雨主要是依据自然降雨原理，通过飞机播撒或利用高炮、火箭从地面上发射催化剂，如碘化银、干冰、液氮等，从而降低云层温度，形成过饱和水汽；或者向含有过饱和水汽的云层中撒播凝聚核，增加云中的冰晶数量，进而增加雨滴的数量和直径，提高云降水的转化率，从而达到增加局地自然降水的目的。

The relationship between rainfall intensity and interception by canopy is also very osculation. The rainfall intensity diminishes with the increase of rainfall and interception by canopy.

林冠截留与降水强度的关系也非常密切：降雨雨强越小，林冠截留量越大，林冠截留率越高。

Using a neural network algorithm to establish a typhoon rainfall model and to seek the nonlinear relations between the relevant parameters and rainfall intensity is a rational approach. The rainfall data used in this study include rain gauge data and radar data, and is able to reflect the spatial distribution of the precipitation pattern.

雷达具有空间侦测能力，利用地面雨量计的雨量资料与雷达回波的资料，可以将空间中的降雨分布趋势表示出来；本研究当中所决定的台风降雨因子是根据过去相关研究文献所整理出来，而这些台风降雨因子是否能完全模拟台风降雨的机制，尚待观察。

The frist step is selecting any gage that building in the river basin as rainfall center, and adding the nearest rain gauge step by step to calculate the point and areal rainfall for different size of area. Using different gage that in the river basin as rainfall center can get the result of different case.

研究中，先以某个雨量站当成点降雨中心，并逐次纳入邻近雨量站，即可分别得到不同面积下之点降雨及区域面积降雨，依序置换不同雨量站为中心进行相同之分析，即可得到所有可能组合案例之分析结果，利用Gamma分布可进一步推求不同重现期距之点降雨及区域面积雨量，即可建立研究区域之ARF。

Plant can effectively enhance its rainfall retention capacity and improve efficient utilization of rainfall resource through changing rainfall distribution characteristics.

植物能通过改变降雨的分配性能，有效提高其对降水的涵蓄能力和对降水资源的有效利用。

The rainstorm process is a complex and stochastic multi-dimensional process.A correlation exists between the maximal annual period-storm and the rainfall duration,with overlooking many factors,the parameterwill not be a constant.Since 1980s,heavy rain and flood of small basins can be calculated by auto-recording rainfall observation system,and 20-year's self-recording rainfall data can improve the calculation accuraey.

暴雨过程是一个复杂的多维随机过程，年最大时段暴雨xt，p与暴雨历时t的暴雨公式属于经验相关关系，忽略了不少影响因素，因此，公式中参数n值不会是稳定不变的。20世纪80年代以后，随着自记雨量观测应用，到目前已经有20多年的资料系列，小流域暴雨设计的计算就可以直接利用时段实测降水资料系列进行计算，设计洪水时，可根据实测雨量时段资料，计算该设计流域的n值，可提高计算精度。

According to the result of artificial rainfall, the character and factors affectedby soil, rainfall, chemicals, slope length, slope gradient and field mangment practices, for rainfall, runoff,infiltration, soil erosion and soil chemicals, such as NO_3~-, NH_4~+, PO_4~(3-), K~+ and Br~-, are investigated. Thedeterminate methods, influence factors and practical application of the mixing zone depth are also researched.The results can enrich the dynamics of soil, water and nutrient transport, evaluate the soil water and fertilizerefficiency, and theoretically benefit the research of agricultural NSP on loess hill slope. 1. According to the surface transport experiments of soil chemicals under the non-satuation soil and watererosion condiction, for adsorbed PO_4~(3-) and K~+, the time of sheet erosion and rill erosion initiation is coincidentthat of chemicals content in surface runoff climbs, and then their abundant export by surface runoff is urged.
