人口增长（动物繁殖）模型，确定种群的固有增长率和稳定分布，建立稳定收获模型。 (it is about a model of population increasing)

如何用Matlab画图 以西东方向为横轴，以南北方向为纵轴。（选适当的点为原点）将国土最西到最东边界在x轴上的区间划取足够多的分点xi，在每个分点处可测出南北边界点的对应坐标y1 ，y2，(How to use Matlab drawing XiDong direction in the north and south direction for the horizontal axis, for the vertical axis. (choose appropriate point for starting point the west to the east land border on the x axis of interval strokes on the locations take enough in every cent point place xi, can detect the north-south border points corresponding coordinates, y2 y1, )
