| 摘 要： | 通过模型的建立、抽样技术的研究表明，山杨根腐病是一种根病，以感病株数为病害的数量指标，用扩散型指数法和回归模型分析法研究其空间格局，山杨根腐病的空间格局是一个相对静态的均匀分布空间格局，随着时间的变化空间格局也将发生变化。

| Abstract: | Root rot of moutain poplar was studied with establishing model and sampling technique.The results showed that,root rot is a kind of root disease,the quantitative index is disease plant numbers.The space distribution was studied with the method of diffusion and regression analysis,it's a uniform distribution of relative statics,the space distribution will change with the time changing. |
