This paper selected the middle part of taihang mountain as study area. the species diversity, interspecific association and correlation, and niche breadth and niche overlap were studied. the community types, community structure, ecological relationships between species diversity and community types, environmental variables were analyzed in details
本文以太行山中段植被為研究對象，從植物群落的物種多樣性、種間關系及群落優勢種的生態位寬度和生態位重疊三個方面深入探討和研究了該地區群落類型、結構、生態及分佈格局，群落多樣性與群落類型、生境、群落結構之間的關系，以及主要優勢種的種間關系。 -
The paper holds that the degree of competition between enterprises is proportional to their niche overlap in an enterprise ecosystem where the environmental resources are limited
在一個環境資源有限的企業生態系統中，企業之間的競爭程度與其生態位重疊的程度成比例關系。 -
The results indicated that the greater the niche breadth of a species was, the stronger the ability of adaptation to environment and using resources was. the greater the niche overlap value for some species - pairs, the more similar the environmental requirements and resource use. the species with wide niche breadth may have high overlap value with species with narrow niche breadth, and low on the contrary
結果表明，種群生態位寬度越大，對環境的適應能力越強，對資源的利用能力也越強；生態位重疊越大，種群間的生態相似性越大，利用資源的相似性程度越高；生態位寬的種群對生態位窄的種群可能有較高的重疊值，反之則較低；生態位寬度最大的種群不一定為群落的建群種。
