Based on the method , a tracking window method is adopted to track the target , and locate the position of target centroid by adjusting the window self - adaption 本算法采用动态窗口法,利用目标颜色的概率分布特征,锁定目标的颜色分布区域的质心,达到快速准确的跟踪效果。

In modern times , man - made destruction and irrational use make the shrubbery area reduced sharply and lead to insect and rats disaster and fire and aggravate the decline of shrubbery 近、现代以来，人为的破坏和不合理利用使灌木林面积在其自然分布区域内迅速减少，并导致病虫鼠害和火灾的严重发生危害，加剧了灌木林的衰退。
We can draw another conclusion that the increasing of air pollution , smog and aerosol that result in reduce of photosynthetic active radiation would have no obvious influences on the photosynthetic accumulation a 植物分布区域的大小及其是否获得最终竞争优势受coz浓度、温度、辐射强度、降水等环境条件综合作用影响，决非一种因素所能决定。
( 2 ) the construction land increased greatly with fragment degree decreasing , the farmland decreased a lot with fragment degree increasing , and water , grassland increased , orchard and non - used land increased a lot ( 2 )建设用地面积增加和耕地减小幅度较高，建设用地的斑块破碎度略有减小，分布区域集中；而耕地破碎度增加，形状趋于复杂。

The author considered that ploughing deeper and corn residues might form " flat type " boundary soil ( depth = 30cm ) . this kind of profile morphological characteristics could evidently increase the com yields and prevent the erosion of soil 在三角坐标图中，不同形状界面构造土壤的三相组成分布区域是特征性的，因此，我们认为土壤三相组成特征可以作为评价土壤肥力退化的依据。
