Ecological environment factors affecting its growth and development and the spatial distribution characteristics of plant autoeciousness of Hemiberlesia pitysophila were comprehensively analyzed by combining Maxent ecological niche models with geographical information system technique in this paper.

In this study,the species abundance patterns of tree,shrub and herb layers in a oak(Quercus liaotungensis) forest in Dongling Mountain,Beijing,China,were studied respectively with five niche models,including broken stick model(BSM),niche preemption model(NPM),overlapping niche model(ONM),random assortment model(RAM) and dominance preemption model(DPM).

This paper examed the output of four niche models: niche preemption model, broken stick model, overlapping niche model, logarithmic series distribution, in application to three kind of communities of artificial vegetation in Antaibao open mine.

Regarding of the similarity between regional industry clusters and biologic species,and referencing the niche theory of biology,this paper analyzes the characters and rule of regional industry clusters,and provides the niche model of industry clusters,then a case study was done to two industry clusters,which produces similar products.

The ecological niche models (ENMs) can be employed to predict the potential distribution of an invasive species in the invaded area based on the niche requirement of the species in its origin areas, given that its niche conserved when invaded in anothe.

Predicting potential ecological distribution of Bactrocera dorsalis in China using GARP ecological niche modeling;

According to niche theory,the change of Kunming(1996 ~ 2004)land-use type area were analyzed,and interactive intensity of different land use types in Kunming from 1999 to 2006 also were calculated,through land use economic niche model.
