This article describes on the problems of web break,paper face spots during the production of kraft paperboard because of the use of OCC and chemical additives such as modified starch when antiseptic agent is not added.

The result showed that secondary forest fragmented had significant effects on breeding parameters,mainly by patch size,patch shape,patch isolation.

Patch boundary shape and patch size distribution in 9 year restoration succession was studied scale transition points were determined using fractal method.

Then we can figure out the violent degree of changes of the plant spot area and fix the relevant relation of the priority protection order by the Analytic Approach of the Level.

Because the lack of studies on impacts of spatial distribution characteristics of certain patch on ecology process were lack,therefore,this paper sampled and studied the variety of spatial distribution pattern of the mobile dune patches with the grads in the typical regions of Horqin Sandy land with the application of 3S technique.

The fractal dimensions of pasture patches is higher than cropland patches,this indicatc grazing proccss has morn dramatically impact than agricultural action.

The diet selection is influenced by water resource, characteristics of the studied region and soil, and the plant species and the quality of patches, and the characteristics of the animal physiology and the animal communities.
