| 摘 要： | 非点源污染负荷的离散型分布不利于深入研究非点源污染与社会、环境等因素的关系,因此非常必要对其进行空间连续分布处理,但在对离散变量连续化过程中应注意尺度和信息增减等问题.以非点源污染中人畜产污为例,通过构建空间连续分布模型模拟计算人畜产污的数量及其分布.从验证的结果来看,这种非点源污染空间连续分布处理方法不但是必要的,也是可行的.

| Abstract: | The dispersed type distribution of the nonpoint source pollution load is very unfavorable to the study of the relation of the nonpoint source pollution and the other social and environmental factors, therefore it very necessity to carry out the continuous space distribution handling. However, it is very important to notice the problems such as measure and information increase and decrease in the successive dispersed variable. This paper takes the pollution of the population and the livestock for example. The spatial continuous distributed model is established to calculate and simulate the quantity and the distribution of that pollution loads. And we finally verify from the result that this kind of nonpoint source pollution spatial continuously distribution processing technique is not only necessity, but also feasible. |
