In recent years many works have been published concerning the problem of optimal plant-ing density of crops and much attention has been paid to the density at which maximumyield is.attained.Since this density is not always the most profitable one,what is neededin practice is the yield-density curve and not only a single point on it.In this paper at-tempts have been made to establish the quantitative expression of this curve,together witha brief discussion of several formulae proposed by other workers.The first method of approach is to establish the relation of mean head weight (w) to thenumber of culms per unit area (y).It may conform to one of the following equations,as thecase may be:u=a'-b'y (1-2)andw=α+b(1/y)+c(1/y)~2 (1-3)where a',b',a,b,and care constants.From these equations we obtain the correspondingequations for yield-density relation,and those for optimal density,Y_(opt).Thus,from (1-2)we haveW=a'y-b'y~2 (1-4)andu_(opt)=α'/(2b') (1-5)and from (1-3) we haveW=ay+b+cy~(-1) (1-6)andY_(?)=(c/a)~(1/2) (1-7)These equations may be expressed in terms of density x by substituting the following equa-tion into them:y=α+βx (1-1)The second method of approach is to consider the effect of density on total dry weight(W_b) and on a conversion factor K_E,which is the ratio W/W_b,W being the total grain yield.W_b was found to be a logarithmic function of density,and may be expressed asW_b=W_(bo)+Klnx (2-1)where W_(bo)and K are constants.From the fact that head weight w is a linear function of tiller weightW=b((W_(b-α)) (2-3)where a and b are constants,usually both positive,the conversion factor K_E was found tobe a function of mean culm weight,W_b K_E=b-(ab)/W (2-4)The value of K_E tends to decrease as density increases and thereby W_b decreases.The relation between yield and density has been thus obtained:W=YW=bW_b+aby (2-5)Then,substituting (1-1) and (2-1),we haveW=b(W_(bo)+Klnx)-ab(α+βx) (2-7)and the optimal density is (2-8)x_(opt).=1/(βακ)All these equations are valid only in certain density range,though the range is wide enoughfor practical purposes.

Taiwan is one of the festoon islands bordering the western Pacific which is the high seismicity re-gion in China as well as in the whole globol.As to the earthquake,the important thing is at prevention,as is just the same to other natural hazards. The developing productive forces and the disaster reduction and prevention is two aspects of eco-nomic construction,they are supplement each other and not a single one can be omitted.So that,inthis paper,the problem of mitigating earthquake hazards is discussed with consideration of the currentpopulation density and economic development of Taiwan.The author wish that the proper authoritiesof Taiwan may pay attention to this problem.

众所周知,台湾是西太平洋弧形列岛中的一环,是我国也是全球地震的高发地带。对于地震,同其它自然灾害一样,应重在预防。增加生产和减灾防灾是社会经济建设问题的两个方面,二者相辅相成,缺一不可.因此,本文结合台湾现今的人口密度、经济发展等情况,讨论了台湾的减轻地震灾害问题,希望能引起台湾方面的重视。

In this paper, the time and space characteristics of large earthquakes and serious hazard earthquake (dead more than 10) in the world during 1990 - 1995 are studied. We emphasize on the correlation of hazard earthquake , seismicity, humanistic geography , economic geograph original time and other factors . We conclude that the injured or dead is not only depending on the seismic activity , but also local population density , local economic developing level and original time.

研究了1990~1995年间全球大地震活动及重大灾害地震(死亡人数n≥10)的时空强分布特征,着重讨论了灾害地震与地震活动水平、人文地理、经济地理和发震时间等各种因素的密切关系.指出人员伤亡不仅与地震活动性有关,而且强烈地依赖于地区人口密度、经济发展水平及发震时间.
