Urban Ecological space is an important part of urban complex system，and is an important space carrier to maintain urban ecological environment functions and provide ecological products，an important place for urban residents to enjoy a better life，and a reasonable and orderly ecological space is an important guarantee for the healthy and sustainable development of cities. In recently years，with the increasing investment in ecological civilization construction by municipal governments in Henan Province，the ecological space of cities in the province is characterized by continuous increase in area and continuous optimization of spatial structure. However，compared with developed cities at home and abroad and citizens’ yearning for a better life，Henan’s urban ecological space still has some problems，such as insufficient quantity，uneven distribution and heavy use load，for which it is necessary to further increase the effective supply of urban ecological space and guarantee its system stability and type diversity.
