    摘要   PDF (534KB)
    水资源短缺对区域经济发展的影响,一是对区域经济发展总量的影响,二是对区域经济结构的影响,三是对区域经济空间布局的影响.解决水资源短缺,必须从两方面入手:一是调整产业结构,降低需水量;二是调整空间布局减少缺水点的需水量.
    Water resources shortage has become an important object of regional research because it shows serious consequence,e,g.it restricts the economic development in many countries and regions in the world.The shortage of water resources,in the light of supply,is classified into supplying shortage,economic shortage and absolute shortage,and in the light of demand,into baseline shortage,productive shortage and environmental shortage.The effects of the productive shortage of water resources on the regional economic development include the following three aspcts: 1)the effect on the total output target of regional economic growth; 2)the effect on the regional economic structure; 3)the effect on the location and spatial structure of regional economy. At a given target of economic growth,the effect of water resources shortage on economic growth is the functions of economic structure,technological progress,the extent of water saving and the extent of water resources shortage.

    摘要   PDF (532KB)
    将系统思想和综合自然地理观点引入地貌区划研究.提出:①山东省地貌区域单位的等级结构,揭示了山东省地貌区域单位相互联系的等级次序;②过渡性单位的概念;③合理利用山东省地貌区域结构的几点认识.
    1.This article puts forward an ordering frame of the geomorphological units in Shandong Province and discusses the hierarchical interrelation of the frames. 2.A concept of transitional geomorphological unit has been suggested.Recognition of this type of unit in geomorphological regionalization has important theoretical and practical significance. 3.Based on the structtural analysis of geomorphological regions in Shandong,the author stated his views about problems of rational application of the regional structure of landforms in Shandong. This paper is a preliminary study which introduces the systematic view and the idea of synthetic physical geography into the geomorphological regionalization.This approach can be taken as a transitional way through which definite explanation for geomorphological regionalization can be made.This approach is also useful for the rational exploitation of natural resources and for management and harnessing of the national territory.

    地理科学. 1993, 13 (1): 34-40,95.   DOI: 10.13249/j.cnki.sgs.1993.01.34
    摘要   PDF (451KB)
    以长江主要支流之一——清江下游的高坝洲水利枢纽工程为例,探讨了宽谷区岩溶发育及其水动力特征.指出由于地形缓、高差小,因而地表岩溶相对发育;在近岸区存在着"潜流型管道系统",具有纵向导水性强,比降小,排泄点出露高程低等特点,因而是库、坝区防渗的重要部位之一.
    Some characteristics of kast development amd the corresponding dynamic properties of groundwater in a wide valley are studied.It is pointed out that the karst on the surface was quite developed and the relative unobstruted depth of karst developing was small because of the special topographic condition.It is also pointed oot that the karstic piping systems which usually contain the unconfined flow exist in the area close to the river,and along the system have big transmission capacity,small gradient,etc.Therefore,they would be the important domains in which the anti-leakage steps need to be taken.Finally,the formation of the double or more than double goundwater levels,which may occur in the process of drilling,is analyzed and its significance is discussed briefly.

    摘要   PDF (515KB)
    在三江平原沼泽区建设“稻-苇-鱼”复合生态系统的实验研究表明,它具有提高水资源利用率,调节河川径流,改善气候,净化环境,改良土壤,防止沼泽退化,保护濒危动、植物资源等多种生态功能,并进一步提高了生产力和土地治理率.
    In this paper the ecological benefits of complex ecosystem of rice-reed-fish in the mire region of the Sanjiang Plain are presented according to firsthand observations in the field in four years and chemical analysis data of soil,water and product of the system. This system utilizes water resource comprehensively and cyclically and raises its utilization rate.It is able to regulate the runoff of river and maintain the regional water balance,so,it has become an ecological defence for farmland around the complex ecosystem.It makes the air relative humidity rise,similar to mire function so that it prevents regional environment from drying.Some field management measures,ploughing amd irrigatiom in spring,improve thermal regime of soil and appear a positive effect for soil temperature in the reedland.This system also owns ecological function in conserving regional ecological environment and raising its quality.It has ability to clear up many kinds of organic and inorganic pollutant from water and soil.The soil fertility of this system has been increased in comparison with original mire.This system provides a ideal habitat of propagation,foraging,nidation and fattening for wild precious mire animals,both the quantity and composition of mire animal have increased obviously after exploiting mire in this way.The system plays an important role in conserving rare mire animals and maintaining ecological balance of mire region.This exploitative model improves the productive force as compared with mire and raises the land-control rate in this area.We believe that exploiting mire in the way of growing rice and reed and fishing is one of the ideal models for wide distributional region of mire.It creates a new path for our country to develop mire.

    从分析各种类型的光谱特征、生态特征入手,对三江平原地区的沼泽进行研究.通过遥感信息的光学和计算机处理与分析,确定了沼泽类型的分布范围和面积.为我国大范围沼泽调查开辟了一条新的途征.
    The Sanjjiang Plain is one of the biggest marsh areas and the most concentric distribution area of marsh in our country.The area of marsh makes up 10.3% of the total region.Based on the principle that marsh types can be distinguished on the Landsat image we make marsh plant community as a basis dividing marsh types.There are 6 marsh types:Carex lasiocarpa marsh,Carex pseudoca raica marsh,Phragmites communis Deyeuxia angustifolia marsh,and Glyceria sp-Carex sp marsh,Carex sp marsh and Carex marsh with taro in the whole region. After analysing spectral curve characteristics of marsh waterbody,marsh soil, marsh plant and difference among them and non-marsh waterbody,soil,plant we think that spectral curves of marsh plant represent spectral curve characteristics of marsh to a great extent.The marsh plant grows on water and soil of marsh.Various types of marsh plant reflect different environmental conditions,different soil and water sources and marsh waterbody existence form.The extractive experiments of Carex lasiocarpa marsh, Carex pseudocuraica,peat and its quality were done with the method of optical image processing.Applying Landsat information of multitemporal images,through optical enhancement,enhancement of digital images based on band,image classification processing and false colour composite technology image of various marsh types have been extracted satisfactorily.The marsh types,the range of distribution and the area of various marsh types were determined by field investigation and verification.Thereby,it is obvious that remote sensing is an effective method in marsh survey of vast extent into which human being go difficultly.

    刘琪璟, 王战, 王少先
    地理科学. 1993, 13 (1): 57-61,96.   DOI: 10.13249/j.cnki.sgs.1993.01.57
    摘要   PDF (354KB)
    距今1580±70年(公元408±70年)长白山火山爆发,植被遭严重破坏.火山锥体上部的偃松群落因历次火山爆发而消失.近期火山爆发前,高山、亚高山上部植被与现代相似,只是林线由原来海拔2200m 左右下降到现在的2000m.今后林线将继续回升.
    A lot of tree residues(wood fossil)were found under the pumice layer in alpine and subalpine vegetation in the Changbai Mountain.The residues of Betula ermanii and Pinus pumila distributed from 2050 m to 2160 m in the south slope.Based on 14C dating, the residues were covered by a volcanic eruption happened 1580?70 years(408?70 AD)ago.Pinus Pumila communities disappeared after volcanic eruptions.From 1200 m to 1300 m asl in the east slope,the tree residues are dominated by Larix olgensis,as well as Picea jezoensis var.komarovii,Abies nephrolepis and Betula platyphylla etc.The palaeovegetation is similar to the current.In 2150 m asl of the east slope where the current vegetation is tundra,the only species of residues found under the pumice is Larix olgensis.Because of volcanic eruptions,the timberline lowered from original 2200 m to current 2000m asl.The forest from 2000 m to 2200 m asl was replaced by tundra after the events.The timberline is getting higher,but very slow.In the bare land of volcanic rock, vegetation succession model is.lichenes-moss-vascular plant communities,and the pumice bare land is occupied directly by vascular plants.

    地理科学. 1993, 13 (1): 62-68,96.   DOI: 10.13249/j.cnki.sgs.1993.01.62
    摘要   PDF (483KB)
    大气 CO2增加导致的全球气候变化在空间上存在着显著的差异.采用不同方法得出温度和水分变化的地域差异是基本一致的,由此,对不同地区农业生产可能造成的影响也是不同的.因此世界各国对 CO2这一全球性环境问题企图达成协调一致的行动纲领可能是困难的.
    More and more attentions have been paid to the global warming caused by CO2 concentration in atmosphere.It may be considerably important for geographers to investigate the responses of every region in the world to the global temperature rising.The regional differences of temperature increase and rainfall change relating to the CO2-induced global warming have been reviewed,and the implications of the regional differences in climatic change,both for ecosystems and the agriculture over each continent, have been discussed. The temperature increase will probably be more obvious in the high latitude zones than that in the low latitude zones,and the rise of summer temperature in the eastern U-nited States will be larger than that in the eastern China.It has been confirmed that the central North America will become drier in a warmer earth,while North Africa,most parts of India and the eastern China will be quite possible to experience more humid climate on the background of the future global warming. Some regions on the earth will suffer from the global climatic change,others will benefit from it.The author,therefore,considers it possibly difficult for all the countries of the world to reach an agreement on the action to deal with the CO2 problems in the coming years.
