Under the background of digital DEM of maor mountain area, and through the program of Avenue in Arcview, the result of potential ravine highly inosculates with the real ravine. With the comparison of potential ravine and real ravine, it can reflect the developing tendency of ravine in this area. Through positioning with GPS and investigation in this area, we can divide the potential ravine of this area into three forms, that is parallel ravine area steep ripe ravine area and evenness swamp area. It can provide scientific reference for forest management and tree planting, and it is a new theory to prevent soil and water loss, and carry through the ravine controlling by people.

在数字化生成的帽儿山地区DEM基础上，通过二次开发生成的潜在沟系，具有与现实沟系高度的吻合性，并通过与现实沟系的比较，能客观的反映出该地区沟系发生、发展的趋势，借助于GPS的定位及实际踏查研究，可将帽儿山地区的潜在沟系划分为平行沟系区、陡坡显沟区和平坦沼泽区三种类型，可为合理的森林经营和植树造林提供科学的借鉴，并为防止水土流失，进行沟系治理提供了新的理论依据。

In this paper, each of single data stream that is included in data streams has same attributes set as other,the unit of single data stream is tuple,and same attributes set is included in each of these tuples.Reservoir algorithm is used to sample from these single data stream respectively,then some multiple snapshot windows are constructed,the relationship between these single data stream and multiple snapshot windows is bijective mapping,the relationship between attributes that are included in tuple and snapshot windows that are included in relative multiple snapshot windows is bijective mapping,and the relationship between basic windows that belong to same snapshot window and the attribute values that come from different single data stream is bijective mapping as well,that is,these attribute values come from same attribute that is comprised by different single data stream.

针对以元组为单位流入的具有相同属性集的多支单数据流组成的多数据流，提出了分别对每支单数据流进行蓄水池抽样，构造一一对应于各单数据流的若干个多快照窗口，即两者之间是双射关系，可以将多快照窗口串行置于主存中，将元组包含的属性与多快照窗口中的各个快照窗口一一对应，且使得同一快照窗口中的各基本窗口与取自其对应的单数据流的属性值样本一一对应，然后对这些相互独立的样本进行方差分析。
