Based on field investigation and historical data analyzing, the characteristics and causes of flood disasters of Qinba Mountain area were discussed in this paper. Take the harnessed Watershed and unharnessed Watershed as comparative study objects, through analzing the two typical watershed land using and rainfall-runoff dynamic data, combinating the in-situ soil infiltration field testing, a rainfall-runoff model of small watershed which was appropriate to Qinba Mountain areas was built based on improving the SCS model. And then the influence of soil and water conservation measures on the flood processes was analysed.

本文通过野外调查与历史调查资料，阐述了秦巴山地区洪水灾害的特点及成因，以治理流域与未治理流域为对比研究对象，通过对两条典型流域的土地利用状况分析，结合土壤入渗原位测试，充分利用降雨、径流动态观测资料，以SCS模型模拟降雨径流为重点，建立适合于秦巴山地区小流域的降雨径流计算模型，分析水土保持措施对于洪水的作用过程。

At Shannon airport the amount of rainfall was 67 per cent above normal, in Claremorris it was 33 per cent above normal and at Valentia Observatory rainfall was 20 per cent above normal.

Shannon机场比正常水平高出67％，Claremorris高出33％，Valentia观测站的降雨量高出20％。

The stages in which no flood occurred in high valley flat were of normal rainfall or less rainfall.

在这16个洪水阶段之间没有洪水发生的阶段是降水量正常或偏少的阶段。

Even if average year rainfall is about 2515 mm in Taiwan, the usage of surface water resources is limited due to the cliffy terrain and weak geological structure, steep slope and short stream length, unequal rainfall distribution on space and time.

台湾地区平均年降雨量约2515mm，在空间与时间上分布极为不均，加上地势陡峻，河川流短，地质薄弱，冲蚀严重，可利用的地表水资源相当匮乏，必须依靠水库拦蓄水源，使水资源能有效利用。

Rainfalls can " deposit " the co2 in air , making it to take part in the process of karst , to dissolve and corrade carbonate rock . co2 concentration in soil become lower after heavy rainfall and become higher after general rainfall .( 8 ) the value of chemical characteristic of soil water in the high elevation area is lower than that in the low elevation area

降雨可以对coz产生影响，&沉淀&大气中的co ：，使其参与到岩溶作用中，溶蚀碳酸盐岩；降雨对土壤空气中coz的影响与雨强、雨量有关，降雨量、雨强较大时，土壤空气中的c02产生受到抑制，降雨量和雨强较小时，土壤空气中的coz浓度升高。

Starting with the elevation of underground water resources and a safe level of mining through variable system theory, this paper analyzes the conditions of underground water resources based on the well-studied determination method of determining the two hydrographical coefficients: rainfall infiltration replenishment rate and irrigation replenishment rate. Then considering irrigation, rainfall, drainage and other related factors, a mathematical model is set up for the calculation of underground water storage,exploitation on water regulation. After analyzing the adaptability of molepipe drainage, an underground water table regulation is given out.

论文从灌区的地下水资源及其可开采量评价分析方面入手，在对两个主要的水文地质参数即降雨入渗补给系数、灌溉入渗补给系数确定方法研究的基础上，对灌区的地下水资源状况进行分析，依据灌区的灌溉、降雨、排水条件及各种现状因素，建立了地下水资源量计算的数学模型，西安理工大学工程硕士专业学位论文计算得到青铜峡灌区地下水的最大补给量和可开采量；另外对在开发利用地下水资源过程中的地下水位的调控进行了初步的探讨，在银北灌区开展对暗管排水调控地下水位的试验研究。

Based on the experimental data from Guilin Irrigation Experiment Station in Guangxi Autonomous Region,the relation of rainfall utilization and surface runoff in paddy fields under different rainfall frequency and different irrigation regimes is studied;i.e.combining shallow water depth with wetting and drying,intermitted submerged irrigation and traditional flooding irrigation.

以广西桂林试验中心站多年实测降雨资料为依据，研究不同降雨频率下稻田降雨利用率及水稻不同生育阶段的径流关系，以期为减少农业面污染的水肥管理提供理论依据和实践指导。1材料与方法桂林试验站多年来采用传统灌溉、间歇灌溉和&薄、浅、湿、晒&灌溉方式进行早稻和晚稻田间试验。

By using of NCAR/NCEP reanalysis daily average data from 1950 to 2002 and daily rainfall of 355 stations in east China from 1957 to 2000 , whole layer vapor transportation fluxes of all globe are calculated , climatic characters of East-Asia pentadactyl vapor transportation in summer are analysed , differences of pentadactyl vapor transportation in strong vapor transportation years and short ones , and relations of vapor transportation in East-Asia and rainfall in east China.
