The dynamic mechanism of the optim; control of regional human-earth system is to simulate the optimal distance between "man circle" an "earth circle". The spatial structure of the optimal control includes core area, occurrence area, sustair ing area and function area.

The method for the point sets selection of point Hough transform and the scan direction for image of searching the point sets were improved by using the geometrical characteristic of the concentric circles:The center of the concentric circles was obtained in the accumulative array firstly,radius was obtained by the mean of distance between the circle center and every edge points afterwards,both the circle center and the edge of the concentric circles were detected accordingly.

利用同心圆的几何特点对点Hough变换边缘点的点组选取方法和搜索点组的图像扫描方向进行了改进：首先由累加阵列确定同心圆的圆心，然后由圆心到各个有效边缘点距离的均值求出半径，从而检测出同心圆的圆心与边缘。

"You may create lots of splashes in your life, but the waves that come from those splashes will disturb the peace of all your fellow creatures," he said. Remember that you are responsible for what you put in your circle and that circle will also touch many other circles.

他说："在生命的水面上，你也许能激起许多波纹，而你所激起的波纹也会打破别人的平静，"要谨记，对你所激起的波纹中所包含的东西负责，因为这些东西会接触、影响到别人的波纹。

"You may create lots of splashes in your life, but the waves that come from those splashes will disturb the peace of all your fellow creatures," he said,"Remember that you are responsible for what you put in your circle and that circle will also touch many other circles."

The basic principle is based on spherical astronomy and elementary geometry of the trajectory mapping method based on the observation of a celestial body zenith distance, then the ship is located in order to sing the next point as the center of this satellite zenith distance of the ship's position as the radius of the circle, observing the same two objects, or objects at different times of the two observations, we can get two ship's position round, then the ship must have been a point of intersection of two ship's position on the circle.

其基本原理是建立在球面天文学和初等几何中的轨迹作图法基础上的，观测一个天体的天顶距，则航船就位于以星下点为圆心，此星天顶距为半径的船位圆上，观测两个天体或者不同时间同一天体的两个观测值，就可以得到两个船位圆，则航船一定在两个船位圆的一个交点上。
