Tenth. A series of mathematical model of genetic mechanism of common population have been established,they are mathematical description of genetic mechanism of common population, so the population that the population genetics researching have extended from panmixia population, inbreeding population,selfing population to common population. It will start the new research territory of population genetics and promote its development.

本文建立了普通群体遗传机制的一系列数学模型，这是对普通群体遗传机制的数学描述，它使群体遗传学所研究的群体由随机交配群体、近亲交配群体、自交群体扩展到普通群体。

The results showed that Liquidamba formosana, Quercus acutissima, and Quercus fabri populations had the dominant positions in the forest community of Purple Mountain Area of Nanjing. During the growth process, the mortality of L. formosana, Q. acutissima, and Q. fabri were higher in low age. After entering into the middle-age stage, the upper space was occupied by oak and L. formosana population all died. The mortality of Q. acutissima and Q. fabri populations were increased with the increasing of diameter class. L. formosana population in the Purple Mountain Area of Nanjing belonged to be the typical growing population and Q. acutissima population was a decreasing population. Q. fabri population belonged to be the growing population on the whole, but the diameter class in middle parts was incomplete and the population was difficult to be renewed. Among the studied quadrate, only one dominant population showed an aggregated distribution and other dominant species showed the random distribution. Either, all the dominant species in all the quadrates presented random distribution.

结果表明，枫香种群、麻栎种群和白栎种群在南京紫金山地区森林群落中占有优势地位；枫香种群、麻栎种群和白栎种群在其生长过程中，在低龄时期，死亡率都较高，进入中龄期后，由于上层空间都被栎木占据，枫香种群全部死亡，而麻栎种群和白栎种群的死亡率则随着径级的增大而增大；南京紫金山地区枫香种群属于典型的增长型种群，麻栎种群属于衰退型种群，白栎种群总体上属于增长型群落，但中间径级不完整，种群更新较为困难；在所研究的每一个样方中，一般只有一个优势物种呈聚集分布，而其他优势物种呈随机分布，或样方中所有优势物种都呈随机分布。

From late 1970s,Chinese technological staff began to do deep research on the issue of population control and achieved a lot of researching results at three levels: population database , technology and soft ware of population analysis, the informational system of population management, the surporting system of population strategy and population forecast and software are at practical research level; the system control theory of nonlinear population distribution parameter in this article is of basic research.

从七十年代末，我国科学技术工作者开始对我国人口控制问题进行了深入的研究，分别从三个层面取得了许多研究成果：人口数据库、人口分析技术和软件、人口管理信息系统、人口决策支持系统、人口预测和软件等，属于应用研究层面；人口系统论和人口控制论等属于应用基础研究层面；而本文的非线性人口分布参数系统控制理论，则属于基础研究。
