    Regularities of wind-erosion of different land-use types in Yongding River sandy land, Beijing
          
    The threshold wind velocity of a number of variables was studied in four different land-use types: farm land, forestland, wild grassland and a flood plain in the Yongding River sandy land in Beijing.
          
    The following conclusions were drawn: 1) The order of decreasing threshold of wind speed for sand displacement and surface roughness were forestland, wild grassland, farm land, sparse wild grassland and flood plain.
          
    At a height of 0-20 cm, the height increased while the sediment discharge percent of sand flux decreased; there were significant differences in the sand flow formation under different land-use types.

    There are usually various calamities,such as:flood,water-logging, drought,soil solinity,etc.,in the agricultural production of Hebei Plain. To make them under control,we have and take combined measures of various kinds.While,among these,the developmant as well as the utili- zation of the ground water in the shallow subterraneous layer must be taken as the essential one,by which the efforts of different measures might be accommodated.Since the development of shallow layer ground wa- ter would make possible the irrigation of land;lower the level of ground water;keep the soil from further salinizing;and,besides,increase in- fihration and percolation rate of precipitation and surface water as well. Thence,the multiple benefits of preventing local district from being water-logged,meliorating soil of alkaline and saline and raising the rate of use of water resources would be achieved.

    河北平原农业生产上存在着洪、涝、旱和土壤盐渍化等多种自然灾害。治理这些灾害,必须采取综合措施。其中应当以浅层地下水的开发利用为中心,谐调各项措施的作用。因为,开采浅层地下水,不光解决灌溉问题,还可使潜水位降低,抑制土壤返盐,增强降雨和地表水的入渗能力,兼收防治涝、碱和提高水资源利用率的效果。

    本文以社会生产力的发展和地理学这门学科内的矛盾运动为依据,结合在本世纪末我国经济发展的总目标,对地理学发展的趋势进行了研究。认为在第一阶段(1980—1990年),地理学主要应为调整我国工农业结构与布局服务.同时,还要认真研究如何改善我国各重点地区的生产条件和协调人地关系问题.在第二阶段(1990—2000年),地理学应为振兴我国经济服务,认真总结自然——经济综合体的成功经验,深入探索人地相互作用的规律,开展地理预测预报工作.此外,还指出生态地理学,也应受到我国地理学界的高度重视.

    The South-to-north water transfer is a magnificent project in China, which brings excess water from the Yangtze River in the south to the arid areas of North and Northwest China. The proposed East Transfer Route would pass through and supply water to the Huang-Huai-Hai plain,The liuang-Huai-Hai plain is a weakly or easily salinized region . Owing to the influence of the pacific monsoon, this region has always been suffered from disasters of drought, flooding, salinization and alkalization throughout the history. Under this specific natural condition and human activity , sail salt-water movement is significantly characterized by seasonal changes. Soil is in the process of modern salinization,only varying in degrees of salt accumulation with location and times. Therefore, in the design and implement of the South-to-north Water Transfer, attention should be paid to the control of soil salinization .Alter the water is transferrer, the irrigation area in the Huang-Huai-Hai plain will be enlarged. There will be a beneficial effect on improving water condition of this region, leaching soil salt and promoting agricultural production. At the same time, the present salt-water balance of the region will be changed. The districts with poor natural drainage and without artifical drainge system might be confronted with secondary soil salinization.If the four lakes in the south of the Huang-He are used as regulation reservoirs in the South-to north Water Transfer project, then the elevation of the original storage level of the lakes will have a definite effect on the drainage of the main channels in the west of the four lakes and on soil salinization.From a long-term point of view, it is necesary to dig deep trough or to deepen the bottom of the lakes to meet the requirment of storage capacity and storage level of the lakes. In addition, the channel of drainage flooding and controlling seepage should be excavated along the west side of the four lakes, to reduce and control groundwater level of the region along the lakes, at the same time, pumping drainage station should be established at the outlet of the main drainage channel, to settle drainage outlet and increase capacity of drainage flooding.The conveyance of water for a long period of time in the main canals, especially in the stretches where the level of transported water is higher than the land surface, would lead to the formation of high-water-table zones on both sides of the canals, owing to a large amount of seepage of canals. The groundwater runoff in the left side of the main canals would impede in varying degrees and block the drainage of underground runoff and might lead to a general increase of the level of groundwater and aggravate soil salinization along the canal. Both an adequate engineering drainage system of controlling or intercepting seepage and an agricultural technique should be considered. At the same time, a scientific management system for the supply of transferred water should be worked out. So long as more attention is paid and appropriate and reasonable measures of water management, agricultural and engineering system are adopted, soil salinization could be prevented or controlled.

    本文简要分析了南水北调东线输水工程实施后可能引起黄淮海平原土壤次生盐渍化的原因,并提出了相应的防止措施。
