In connection with experiments on the control of the rice stem borer, aseries of observations were conducted in 1949 to 1952 in Canton to determinethe form of the distribution of the moth, the egg-mass and the larval popula-tions of this species. It was found that the moth and egg-mass populations inrice seed-beds are in essential agreement with the random distribution of thePoisson series. The larval population in spring-crop fields apparently conformsto the contagious and the negative binomial distributions. The larval population during hibernation period appears to be neither of the random distribution norof the contagious type but agrees with the negative binomial distribution. The population distribution of the injured stems, characterized by the ap-pearance of "dead-hearts" and "white ears" was also studied. The "dead-hearts"popolation in autumn-crop fields conforms with the contagious and the negativebinomial distribution. The distribution of the "white ears" is not at random. It iseither in essential agreement with the contagious or with the negative binomialdistribution, depending on the size of the sampling unit. Based on the form of population distribution the questions of sampling tech-nique, the design of field experiments, the transformation of data for statisticalanalysis, as well as the habits and control of insects have been discussed inrelation to the rice stem borer. Since the populations of larvae and "whiteears" differ significantly from the random distribution, a new technique forsampling has been proposed. It is hoped that this may be useful in the investi-gations on the relative effectiveness of control operations and for census purposes.

According to the some year data of line transect census monthly in the various habitats of Taiyuan Basin, this paper has comprehensively analysed the variable regularity of bird's phase; the structural characters of bird's community composition in summer and winter in the various habitats; the variable regularity of quantity of different ecological group birds distributing in the various habitats; and the habitat factors which bring about the change and the difference. It point out the narrow habitat birds (the hydrocole avifauna, the nemoral avifauna and the hilly avifauna) that they are main ecological type birds affecting the structural characters. And they are closely connected with seasonal climatic condition and habitat fitness (including water condition, vegetation series and composition) .

本文根据历年在太原盆地各个生境逐月鸟类路线统计的资料,综合分析了一年内的鸟相变化规律;各生境夏季、冬季鸟类群落组成的结构特征;不同生态类群的鸟类在季节分布和生境分布的数量变异规律,以及引起这些变化和差异的生境因素。指出狭生境分布的水域鸟类、林栖鸟类以及丘陵鸟类是影响各生境鸟类群落结构特征的主要鸟类。而这与季节气候条件和生境的适合度(包括水域条件、植被的层次和组合丰度)有密切的关系。

This paper applies system identification technique to the population system of China and proposes an economical and effective method of estimating Chinese population model parameters. Based on very limited and incomplete statistical data available for the past 25 years, including two censuses, we have deduced the estimation and forecast data of the population model parameters of China. The validity of these data is sufficiently verified by the population prediction for the past 25 years the yearly forecast accuracy of the total population being within 1%. As the available statistical data here are too limited for the purpose of directly estimating those parameters we propose the use of an analytical expression for the age-specific survivals and a special identification method corresponding to it, this not only makes the identification possible, but also provides an useful empirical formula for demography.

本文应用系统辨识技术于人口系统,提出了辨识我国人口模型参数的一种经济而有效的方法;同时根据过去25年非常有限的统计(包括普查)数据,获得了我国全国人口模型参数的辨识和予测结果.其有效性通过过去25年人口预测得到了验证,其中每年总人口的预测精度基本上在1%以内.由于统计数据十分有限以至于不可能直接估计模型参数.本文提出了按龄留存率的一种解析表达式及与之相应的独特的辨识技术,不仅使辨识成为可能,而且为人口估算提供了一种有用的经验公式.
