By using random and aggregated distribution-abundance models,this paper studied the relationships between species abundance and distribution patterns of broad-leaved Korean pine(Pinus koraiensis)mixed forest in Changbai Mountains of China under different spatial scales.

The results showed that the scenic spots in the Wuyishan scenery district are aggregated distribution.

Animal population spatial distribution maybe classified as the uniform distribution,the random distribution,the aggregated distribution(negative binomial distribution, Neyman distribution, Poisson-binomial distribution) for the different features of animal species,population,habitat and so on.

The results showed that the spatial patterns of this species conformed to Neyman distribution(aggregation distribution).

Tai Shan were determined by means of several indexes of aggregation and regression methods ,The results showed that over-wintering eggs on leaves are belonging to aggregation distribution which was resulted in by egg-laying characteristic of Oligonychus perditus adult or affected by environmental factors.

The spatial distribution was aggregation distribution.

In this paper we defined distributed uncertain Max(Min) and Top-k queries,and designed distributed aggregation algorithms based on several filtering strategies.

Aiming at different developing instances of our country s knowledge-intensive producer service at present and considering the influence to centralization mode which comes from industrial characteristic and city orientation,this paper analyzes and illuminates three kinds of typical knowledge-intensive producer service s territorial centralization modes and these characteristics.
