The relative frequency of land use pattern is caculated according to the belt ransect.The variation of land use pattern is studied with the metheds of the species association of plant ecology and the β_w di-vesity index,The result suggests that there is a regular change from the nearsuburb to the middlesub-urb,for instance’the relative frequency presented of the cultivated land forest land and rural settle-ments gradually increases.

The relative frequency of land use pattern is caculated according to the belt ransect.The variation of land use pattern is studied with the metheds of the species association of plant ecology and the β_w di-vesity index,The result suggests that there is a regular change from the nearsuburb to the middlesub-urb,for instance’the relative frequency presented of the cultivated land forest land and rural settle-ments gradually increases. The decline in cultivated land and forest land and the rise of land-using in towns factorise have resulted in a series environmental problems in recent 30 years.There exist associat-ed or excluded relations among the different land use petterns,The divei.sitiss of land use are most abun-dant in middle-suburb and decrease from middle-suburb to near of far-suburb,There is an increasing tendency of diversity in recent 30 years.

根据样带样方计算土地利用类型出现的相对频率,用植物生态学的物种关联和β_w多样性指数研究万县市郊区土地利用格局的变化。结果表明,近郊至远中郊呈现规律性变化,如耕地、林地、村庄出现的相对频率由小变大;近30年来耕地和林地减少,城镇工矿用地增加,并带来一些环境问题;各种土地利用类型之间存在着联系或排斥的复杂关系;土地利用多样性以中郊最大,向近郊和远中郊变小,并且近30年来都向多样性增大的趋势变化。

The temporal variation of China's grain production development is studied comprehensively and systematically in this paper. First, the research method about temporal variation of China's grain production development is discussed. After analyzing the common method such as “stage method” and “step method”, the author proposed a new opinion and a method named as “gradual variation method”, and worked out a new formula to calculate “comprehensive variation ratio”. Second, taking the statistic data of historical...

The temporal variation of China's grain production development is studied comprehensively and systematically in this paper. First, the research method about temporal variation of China's grain production development is discussed. After analyzing the common method such as “stage method” and “step method”, the author proposed a new opinion and a method named as “gradual variation method”, and worked out a new formula to calculate “comprehensive variation ratio”. Second, taking the statistic data of historical national annual total grain production (from 1949 to 1995) as source data, the author analyzed the temporal variation characteristics of China's total grain production development by using the author's research method. Three temporal variation characteristics of China's total grain production are as follows: (1) The increase tendency of China's total grain production is very obvious; (2) The average increase ratio of China's total grain production is nearly 3%; (3) The trend of China's total grain production increase ratio is reducing. Third, the temporal variation mechanism of China's total grain production is researched by using relative analyses method and gray interrelation analyses method. The analyses result is that the first direct driving force of China's total grain production development is grain crop yield, and the second is grain crop sown area. Finally, the tendency of China's grain production development is studied and predicted by comprehensive dynamic prediction method and equal dimensional GM(1,1) dynamic prediction method. Three prediction schemes are obtained by each prediction method, and the final prediction result is that China's total grain production will be more than 500 million ton by the year 2000.

文章对我国粮食生产发展的时序变化进行了全面系统的研究。剖析了“阶段论”、“台阶论”等粮食生产发展研究的常用方法,提出和论述了“渐变论”的观点和方法,建立了“综合增产率”计算模型。然后,应用“渐变论”对1949年~1995年中国粮食总产量进行了定量研究,从粮食总产变化趋势和变化驱动力两方面,深入地分析了粮食总产的时序特征。最后,应用两种方法对粮食总产进行了动态预测,预测2000年我国粮食总产可突破50000×104t。

The increasing tendency of the floating rural labor force is followed by the steady advance in the process of the rapid development of socialist market economy and industrialism.Though the phenomenon of floating rural labor force came into being in the19th century of China's modern society,and has never ceased since the founding of the PRC,the wave of the floating rural labor force in the newperiod is totally different fromthe ones in any former period.Such differences can mainly be found in the following...

The increasing tendency of the floating rural labor force is followed by the steady advance in the process of the rapid development of socialist market economy and industrialism.Though the phenomenon of floating rural labor force came into being in the19th century of China's modern society,and has never ceased since the founding of the PRC,the wave of the floating rural labor force in the newperiod is totally different fromthe ones in any former period.Such differences can mainly be found in the following three respects:the difference of the main occurring causes,the difference of the presenting characteristics of the times as well as the difference of the functions of the farmers'self development and improvement.

伴随社会主义市场经济迅速发展和工业化进程的稳步推进 ,农村劳动力流动也呈现出加快的趋势。尽管农村劳动力流动在中国进入近代社会的十九世纪就已经产生 ,并且新中国成立后也未停止过 ,但是 ,新时期涌现出来的农村劳动力流动潮却与以往任何时期不同。这种不同主要表现在三个方面 :产生的主要原因不同 ;呈现的时代特征不同 ;对农民自身发展和完善的作用不同。这种流动带给农业和农村的影响是极其深刻的 ,产生的意义是十分深远的。
