    Rainfall formulas for the design of industrial and urban areas express the relationship between intensity, time and frequency of intense rainfalls. Formulation of these relationships requires the statistical analysis of self-recording rainfall data. For the industrial and urban areas in China, the value of n in the formula i= is found to be within 0 .45 to 0. 65, the time of duration being selected in the limits of 5 to 120 minutes. Curves of equal values of q20, n and C in the formula q= are plotted for various districts of China. As the formula is at present much used in the storm drain design of Chinese cities, it is hoped that these curves may be helpful for the designers. Due to the fact that the self-recording data of intense rainfalls of many cities in China are rather short in duration, and many cities do not yet possess self-recording data, the use of annual rainfall for calculating the design rainfall of storm drains as proposed by and Prof. has attracted the interest of a great many Chinese engineers. After analyzing the records of different Chinese cities, the writers obtain the formula q20= 0 .055HdB0.75, and comparing with the results obtained from statistical analysis of self-recording data, the deviation of this formula is found to be in general within 10-20% for the cities the records of which having been analysed. As many cities in China possess the records of daily and hourly rain fail data, the writers propose methods to use these records in the design formulas of storm drains. Comparison of these results with the results from statistical analysis of self-recording data are given by plotting them on log-log paper.

    After soil survey of the whole region,it is found that the soils of the North China Great Plain consist of four great soil groups including drab soil,light meadow soil,glei swamp soil and saline soil.The term“calcareous alluvial soils” formerly used hardly interprets any mean of soil formation and productive cha- racteristics. The drab soils formerly named as“Shangtung brown soils”are generally located on the alluvial fan and the foot of mountains.Owing to the higher relief,excess drainage and deeper ground water(below 4—6 meters),saliniza- tion is not found.The drab soil is neutral to slightly alkaline in reaction. The chemical data show no evidence of chemical decomposition of clay,but the disintegration of soil particles-clay formation is quite obvious.Along the foot of Taihang range,the drab soils are covered with new calcareous material and bring out the process of recalcification shown by the presence of pseudo- mycelins in the Soil profiles. Light meadow soils are generally distributed in the alluvial plain with higher ground water table laying at 2—3 meters.Owing to the frequency of the fluc- tuation of the ground water in the soil profile,oxidation and reduction are alternately carried out and lots of rusts and mottlings are found in the soil profile of these soils.Under intensive cultivation,the surface soil of light meadow soil is usually loose and mellow and contains lower content of organic matter. The glei swamp soils are formed by the lakeside and in the depressed lowlands where ground water table is quite shallow and sometimes close up to the sur- face.In the depressed lands contacted with mountain foot,longer duration of water-lodging produces strongly gleyed swamp soil with higher content of humus. In the depressed portion of alluvial plain,the temporary water-lodging gives weakly gleyed swamp soil with low content of humus,whilst the strongly gleyed soils are found in the depressed land along seacoast. Salinization of soils is influenced by the ground water and relief.Saline soils are usually distributed in the lowland with higher ground water table and higher mineral content of the water.Irrigation without drainage system will rise ground water table and causes the process of secondary salinization. Saline soils of North China plain may be divided into two subtypes:(1) Saline soil of alluvial plain and(2)Saline soils along the seacoast.The former belongs to the chloride-sulfate saline soils in which the ground water table is about 1.5—2.0 meters and the mineral content of the ground water is about 1—3 grams/liter.In the coastal region,the chloride saline soils are usually found with high ground water table at 1.0—1.5 meter and also high mineral content more than 10 grams/liter.The transitional belt between these two soils above-mentioned is sulfate-chloride saline soils where the ground water table is around 1.5 meter and the mineral content of ground water is 5—10 grams/liter. These four genetic soil types are closely related each other and also alternate between themselves.It is very interesting to study the transitional types among these four soil groups. Between drab soils and light meadow soils,the transitional soil types as meadow drab soils and drab meadow soils are formed under different transitional circumstances.The meadow drab soil is distributed at the bottom of alluvial fan with higher ground water table(1.5—3 meters),while the drab meadow soil is formed on the old riverbed in the alluvial plain with comparatively uplifting relief where the ground water table becomes deeper(3—3.5 meters). Many transitional soil types are also developed between the light meadow soils and glei swamp soils.The worse water lodging condition enforces the meadow soil transfering to glei swamp soil,whilst promotion of water condi- tion by diking drainage cannel or local silting up of lowlands causes the trans- formation of glei swamp soil in to light meadow soil or even to the drab soil. Salinization of soil is always accompanied with the formation of light meadow soil.Rising the ground water table and increasing the mineral content of ground water will induce or enforce the process of sainization of soils.On the other side,desalinization of soils can be carried out when the ground water table becomes lower.When the seatide is shut by dikes and the drainage condition is improved,the saline soil in the coastal region will be transfered to the light meadow soils.

    经过一年多的大规模调查,证实了华北平原的土壤都具有不同的类型和不等程度的发育,其中包括很多土类、亚类和变种,过去简称华北平原土壤为“石灰性冲积土”,是很难反映情况和说明问题的。华北平原的主要成土过程有褐土过程、浅色草甸土过程、沼泽过程和盐土过程。褐土多发育于山麓及冲积扇形地上,地势较高,排水良好,地下水埋藏较深,约在4—6米以下。在降水淋洗之下,可溶盐类皆被淋失,不发生盐演化现象,土壤只及于粘化作用,pH 值多属中性至微碱性。太行山麓的褐土因受石灰性沉积物的覆盖,发生次生碳酸盐化作用,土壤剖面中有假菌丝体存在。浅色草甸土多分布于冲积平原,其形成过程受地下水的影响极显著。地下水埋藏深度约2—3米,也可达4—5米。由于地下水升降频繁,氧化还原作用交替进行,土壤中呈现显明的锈纹斑,但无假菌丝体。土壤疏松多孔而有结构性,因土壤中有机质较少、土色浅淡而多受人为耕作的影响,故称耕种浅色草甸土。洼地及湖淀附近,地下水埋藏较浅或地表积水,土壤发生沼泽化过程。山麓交接洼地,积水时期长久,潜育作用及腐殖质积累均较显著。平原中洼地比较平坦,积水时间亦较短,腐殖质积累和潜育作用都较轻微。海滨洼地中,潜育作用较为剧烈,但有机质的积累则不一致,水浅处的有机质积累较多。因地形及地下水的情况不同,土壤盐渍程度各地不一。盐渍土多发生于山前交接洼地、碟形洼地边缘,以及槽状洼地和地上河流的两侧。有些灌区由于缺乏合理的灌排系统和灌溉制度,土壤发生了次生盐演化现象。华北平原盐渍土可分为内陆及海滨两种:内陆盐渍土多属氯化物硫酸盐土,地下水埋藏深度约1.5—2.0米,地下水矿化度约1—3克/升;海滨盐土区多属氧化物盐土,地下水埋藏深度约1.0—1.5米,地下水矿化度大于10克/升;过渡地带(即海滨盐土与内陆盐土的过渡地带)的盐渍土多属硫酸盐氯化物盐土,地下水埋藏深度约1.5米左右,地下水矿化度5—10克/升。华北平原中的四个主要成土过程是互相联系,而且有过渡阶段的。褐土和浅色草甸土的形成条件,主要在于排水情况和地下水位的不同。所以这两种土壤分布毗鄰而有互相过渡的发展情况。扇形地中下部,地面排水尚好而地下水埋藏较浅(1.5—3米),褐土区中可发育浅色草甸褐土。在泛盐平原中地势相对高起的黄河故道或靠近冲积扇地区,地下水埋藏较深(3.5—5米),可发育褐土化浅色草甸土。泛溘平原中的洼地积水愈久,沼浑化过程愈强,可由沼泽化浅色草甸土过渡至浅色草甸沼泽土或沼泽土。但经人工挖沟排水或洼地淤平以后,土壤可由沼泽土转向浅色草甸过程或褐土过程发展。浅色草甸土中如地下水埋藏浅而矿化度高,则土壤可向盐土方向发展。海滨盐土如不再受海潮影响和改善排水情况,则土壤也可由盐土向浅色草甸土发展。

    Fruit trees in the Baoting vicinity, Hopeh province are seriously affected by chlorosis due to iron deficiency. This is confirmed by the high pH-value and low exchangable iron con-tent of the soil. The pH-value of the soil is about 8.1 to 8.2. The soil in Baoting is rich in carbonate. 20 cm. below the surface is a 35 cm. "black horizon", it contains no exchangable iron and the reduced iron content is considerably low.
