    许学强, 黄丹娜

    本文对近二十年来珠江三角洲地区农村城ft化进程及城镇职能变化和空问分布特征等方面进行了系统的总结和论证。
    Since 1978,rural urbanization has been accelerated owing to the rapid development of commodity agriculture,industrialization and tertiary industry in the Zhujiang River Delta.The population in towns increased naturally before now is mainly increasing mechanically.The towns have been turned from traditional central places into those with various functions,particularly industrial ones. In the Zhujiang River Delta,the density of population and the level of economic changes are high in the core regions,and low in the peripheries; and town population increases slowly in the core regions and fast in the peripheries.In the core regions more industrial towns emerge.The gap has been reduced greatly.The reform of the space construction of the region′s economy the improvement of transportation,the adjustment of the standard of town setting have promoted the space distribution of the towns in the Zhujiang River Delta from being centralized to balanced.

    本文利用45个高空台站及100余地而台站的资料,对华北地区盛夏的强季风(1973年)和弱季风年(19勺年)进行了对比分析.本文对强、弱季风年分别计算了湿静力能量、高低空流场、风的垂直结构、水汽含量及输送、水汽收支及水分循环等项目,从而得知该两年中各要素场明显差异的主要原因.
    This paper,using the high altitude data from 45 stations and the surface data from 100 stations,makes a comparison between strong monsoon year(1973)and weak monsoon year(1972)in North China,and calculates wet static energy,vertical structure of wind of high-and low-level flow fields,the contents and transport of water vapour,the income and export of water an vapour,and water cycle,etc.in strong and weak monsoon years respectively. The following conclusions have been drawn: 1.There was a distinct occluded high energy tongue in the strong monsoon year and a low energy tongue in the weak monsoon year. 2.In the strong monsoon year,western Pacific subtropical high was strong, a wet and warm south air-flow from it met with the drier westerlies nearby 41°N and there were two water vapour transport air-flows.In the weak monsoon year,subtropical high was weak,a wet and warm south air-flow met with westerlies nearby 35°N and there was only one water vapour transport air-flow. 3.The water vapour content of the whole layer in North China in midsummer was 20—40mm and water vapour content was distributed along northeastsouthwest in the strong monsoon year and along latitude in the weak monsoon year. 4.There was a net income of about 95×108m3/month in the strong monsoon year and a deficiency of about 345×108m3/month in the weak monsoon year. 5.Rainfall in North China in midsummer relies mainly on external water vapour supply in both strong and weak monsoon years.

    环境地貌是现代地貌学中一个新兴的部门.本文系统论述了长春市环境地貌的主要特征、区域结构及其与城区建设和发展的关系。
    Taking Changchun City as an example,this paper approaches some aspects of urban environmental geomorphology researches in the plain region of the semi-humid temperate zone.The features of the landforms and the regional textures are analysed with the terrain slope map,the topographic complex degree map and the urban geomorphic regional map.Meanwhile,the urban surface materials and their properties on engineering are studied.It′s concluded that disastrous geomorphological processes are seldom found except tne overflow of the Yitong River.After discussing the relations of geomorphy of Changchun City and the urban historical development,the layout of building areas,road construction,water supply and sewerage network and afforestation,the paper poins out that developing afforestation is the important measure to improve the environment in the city propers,suburbs and their contiguous areas.

    本文研究了松花江氮转化规律。发现低水温条件下(特别是冰封期)氨氮的实测浓度变化不符合目前广泛采用的一级动力学模式,氮扭的实测浓度主要受有机氮生成氨氮的速度和氨氮衰减速度两方面制约。应用化学动力学"连续反应"理论建立了松花江氨氮水质模型。在此基础上计算了松花江氨氮污染环境容量.
    On the basis of studying the transformation principle of nitrogen in the middle-stream of the Songhua River the authors found that the change of real measured concentration of ammonianitrogen did not conform to the graded dynamic model adopted extensively under low water temperature(especially in freezing phase).The real concentration of ammonianitrogen is mainly affected by the speed of transforming organonitrogen into ammonianitrogen and the speed attenuation of ammonianitrogen.And the authors advance that the water quality of model of the Songhua River should be set up with the theory of chemical dynamic successive reaction and estimate the environmental capacity of ammonianitrogen pollution in the Songhua River.

    The average value of mineralization degree of water in river system of Dongting Lake is 160 mg/L(the highest is 260mg/L,the lowest is less than 50mg/L).The mineralization degree in rivers of this system presents a decreasing trend from the northwest and southwest of the system and hills north to the Nanling Mountain,to the northeast outlet of Dongting Lake,due to the differences in climate and hydrology,as well as the differences in association of geology,geomorphology and soil.The ion flow in rivers and lakes of this system has an obvious seasonal change. The river system is a strong chemical denudation region.The main factors to influence chemical denudation are precipitation,runoff and soluble and non-soluble substances,and geomorphology and vegetation as well.

    闽江河口区晚更新世以来的气候变迁
    王珏
    地理科学. 1989, 9 (3): 289-290.   DOI: 10.13249/j.cnki.sgs.1989.03.289
    摘要   PDF (157KB)
    闽江河口区晚更新世以来,长期处于构造下沉过程之中,受海平面升降的影响,经历了距今65000年左左的琅歧海侵、距今3—4万年左右的福州海侵和全新世长乐海侵。沉积了数十米厚的晚第四纪地层,含有丰富的孢粉。由于该区地处中亚热带和南亚热带间的过渡地带,气候变迁造成的古植被演化在孢粉组合中表现较为明显。本文收集了闽江河口区十多个钻孔的系统孢粉资料,对照地层划分和14C 测年成果,对该区晚更新世和全新世两个阶段的气候变迁进行综合分析。
