| 摘 要： | Niche theory is one of the most important ecological theories. It is widely applied to analyzing such phenomena as competition among, and evolution of, urban ecosystem functional modules. This paper describes a study concerning＇different functional modules of Kaifeng city urban ecosystem. Niche theory and techniques were used to analyze the changes of these functional modules in the period 1994-2003. The results showed that, in the period 1994-2003： （1） Niche value of the atmospheric environment and urban virescence modules increased, while niche value of the water environment and sound environment modules decreased; （2） niche value of the tertiary industry module increased, niche value of the secondary industry module decreased, while niche value of the primary industry module showed little change; and （3） niche value of the infrastructure, resource distribution, and production ＆ social security modules increased, while niche value of the population module decreased. This study may contribute to macroscopic planning of urban functional modules, economic development, and environmental protection.

| Abstract: | Niche theory is one of the most important ecological theories. It is widely applied to analyzing such phenomena as competition
among, and evolution of, urban ecosystem functional modules. This paper describes a study concerning different functional
modules of Kaifeng city urban ecosystem. Niche theory and techniques were used to analyze the changes of these functional
modules in the period 1994–2003. The results showed that, in the period 1994–2003: (1) Niche value of the atmospheric environment
and urban virescence modules increased, while niche value of the water environment and sound environment modules decreased;
(2) niche value of the tertiary industry module increased, niche value of the secondary industry module decreased, while niche
value of the primary industry module showed little change; and (3) niche value of the infrastructure, resource distribution,
and production & social security modules increased, while niche value of the population module decreased. This study may contribute
to macroscopic planning of urban functional modules, economic development, and environmental protection.
